There are numerous resources available for automatically checking the functionality of proxies. Online checkers are among the easiest to use, offering significant time savings. The verification process can be particularly time-consuming when installing and operating specialized software and programs, especially when a large number of proxies need to be checked. But this guide will explain the function of a proxy checker, detail how the mechanism operates, and cover the key features you should look for to select an efficient tool for your needs.

What Is a Proxy Checker?

A proxy checker is a tool designed to verify the validity and performance of proxy servers, along with determining additional characteristics. Its primary function is to ensure that the proxies being used are operational and capable of delivering the needed functionality.

Validating the effectiveness of a proxy is crucial when preparing to use proxies and web resources, as non-functional proxy servers can significantly impede work or even prevent the completion of tasks. Employing a proxy checker enhances the safety and efficiency of user interactions with online resources and helps in selecting the most appropriate servers for specific needs.

Why Testing Proxies Matters

You’ll learn how testing proxies impacts your workflow and online security.

Proxy speed and latency directly affect your browsing, scraping, or automation tasks. Slow proxies can cause delays and timeouts, disrupting your work and frustrating users. High latency means each request takes longer, reducing efficiency.
Consistent reliability is essential. You want proxies that don’t fail mid-session and keep your connection stable. Sticky proxies or session persistence features ensure your IP stays the same across requests, preventing reauthentication or interruptions.

Anonymity levels matter because they determine how easily websites can detect you’re using a proxy.

Transparent proxies reveal your real IP, which risks exposure and blocks.
Anonymous proxies hide your IP but identify as proxy users, which may still trigger restrictions.
Elite proxies mask both your IP and proxy status, providing the highest privacy. For example, using an elite proxy helps avoid CAPTCHAs and bans on sensitive tasks like ad verification or data gathering.

Using blocked or banned proxies hurts your business continuity. When websites detect and block your IP, your services stall. You lose time and money and potentially damage your brand’s reputation. For instance, an e-commerce scraper failing due to proxy bans can miss pricing updates, impacting competitiveness.
Failing to test proxies can cause serious issues like data leaks, IP blacklisting, and wasted resources. Imagine running a campaign using a proxy that leaks your real IP – your data is exposed, and your IP is flagged for abuse. This wastes computational and financial resources on retries and workarounds.

Practical Checklist

Here’s a practical checklist to avoid these risks:

Test proxy speed and latency regularly.
Verify the anonymity level matches your task.
Monitor proxies for bans or blocks.
Use proxies with session persistence where needed.
Watch for IP leaks and address them immediately.
Replace proxies flagged for abuse or blacklisting.

Real cases show companies losing access to services due to proxy failures, leading to lost revenue and damaged operations. Using a reliable proxy checker online or a SOCKS proxy checker helps you identify these issues early and maintain a smooth workflow.

Key Criteria for Evaluating Proxies with a Proxy Checker

You’ll learn how to evaluate proxies systematically for best performance.

Core Validation Steps

Start by checking if the proxy actually works.
Use an IP proxy checker to confirm it masks your real IP and delivers responses successfully.
Check multiple verification endpoints to avoid false positives.
Measure connection speed and response time. Key metrics include ping, time to connect, and download speed. Good proxies often have a ping under 100 ms and maintain high throughput.

Practical Benchmarks:

Ping: less than 100 ms.
Connection time: under 500 ms.
Download speed: as close to your max bandwidth as possible.

Proxy Characteristics

Anonymity level matters a lot. Know the difference between transparent (reveals IP), anonymous (hides IP but reveals proxy), and elite proxies (hides both IP and proxy use). Websites detect proxies by checking headers and IP characteristics. Use elite proxies for sensitive tasks requiring high privacy.
Geolocation accuracy confirms the proxy IP matches the advertised region. Use geolocation API checks with tools like MaxMind or IP2Location. Be aware of IP spoofing risks and verify more than once to avoid errors.
Check success rates on target websites. Your proxy should get HTTP 200 OK responses, not blocks (HTTP 403), rate limits (HTTP 429), or excessive CAPTCHAs. Also, handle redirects properly to avoid errors.
IP reputation matters to avoid blocked or blacklisted proxies. Use multiple tools to check if an IP has a history of abuse, spam, or bots. A comprehensive reputation check lowers the risk of disruptions.
Protocols supported are another point. Different tasks may need HTTP, HTTPS, or SOCKS5 proxies. SOCKS5 often handles UDP and TCP, offering more flexibility. Consider if you need residential or datacenter proxies since they differ in trust and speed.
Additional criteria include bandwidth limits, how many concurrent connections the proxy allows, and supported authentication types like basic, digest, or NTLM.

Evaluation Checklist

Here’s a practical list for evaluating proxies:

Confirm working status via multiple endpoints.
Measure speed: ping, connection, download.
Identify anonymity level (transparent, anonymous, elite).
Verify geolocation with APIs.
Test success rate on target sites (HTTP 200 vs. blocks).
Check IP reputation across multiple sources.
Verify protocol support (HTTP, HTTPS, SOCKS5).
Assess bandwidth and concurrent connections.
Check authentication methods available.

Features of Using a Proxy Checker

An online proxy checker enables users to analyze and verify a list of proxy servers based on various criteria such as availability, location, degree of anonymity, and protocol type. It provides detailed reports about each proxy, helping users assess which ones best meet their specific requirements.

Key Parameters and Operating Principles of a Proxy Checker

The operating principle of an online proxy checker involves sending requests through each proxy from a user-uploaded list of IP addresses and analyzing the responses received. This process helps verify the functionality and suitability of the proxy servers. Here are the key aspects that the checker evaluates:

Availability: the checker tests whether the proxy server is available for connections. If the server is unavailable or takes too long to respond, it is marked as down.
Anonymity: this involves analyzing how well the proxy maintains user anonymity. The checker assesses whether the proxy can effectively hide the user's real IP address and whether its use can be detected by web servers.
Speed: the checker measures the time it takes to transfer data through the proxy to assess its speed. This is crucial for applications where delay impacts user experience.
Protocol type: the checker verifies the types of protocols supported by the proxy server, such as HTTP, HTTPS, SOCKS4, or SOCKS5.

Additionally, some proxy checkers can detect incorrect proxy performance, including slow response times, frequent errors, or suspicious headers. These issues might indicate potential problems with the proxy server that could compromise privacy and lead to the leakage of users' personal data. This comprehensive analysis helps users select the most reliable and efficient proxies for their needs.

The Importance of Checking Proxy Validity

The validity of a proxy is crucial for maintaining network security and ensuring the effective online activity of users. Here are the key aspects in which proxy validation plays a vital role:

Privacy protection: valid proxies help conceal the user's real IP address, safeguarding their privacy online by shielding personal data from potential tracking.
Increased security: invalid or compromised proxies can be exploited by attackers to intercept data. By regularly checking proxies, users can identify and discontinue the use of such proxies, thereby mitigating potential security threats.
Performance optimization: using stable and reliable proxy servers can enhance connection performance, which is particularly significant for bandwidth-intensive tasks such as video streaming or online gaming.
Bypassing blocks: some web services and websites may block access via proxies. Through effective proxy checking, users can select proxies that maintain anonymity, preventing web resources from detecting their use.

Over time, the characteristics of proxy servers can change. A proxy that was once functional and offered anonymity might become accessible or transparent, leading to potential risks such as data leaks, traffic interception, and account blocking. Regularly checking proxies ensures that users continue to employ reliable and secure proxies, safeguarding their online activities.

IP Databases and Reputation Checkers

You’ll learn why checking IP reputation is vital to avoid risky proxies. Proxy IPs with a history of abuse or spam can cause blocks, bans, or poor performance.

Key Tools and Interpretation

Start by querying popular reputation tools.

AbuseIPDB reports abuse and spam activity, offering APIs for batch checking and integration with your systems.
IP2Location combines geolocation with proxy detection and also supports bulk processing, enabling you to verify location claims and proxy status efficiently.
Spamhaus provides blacklists focused on email and bot activity, useful for filtering IPs used in spam campaigns.

Interpreting results requires care. Some IPs may show false positives or negatives. Cross-reference multiple sources to get a clearer picture. For example, an IP flagged in one database but clean in others may warrant deeper investigation before discarding.
Automate reputation checks. Set up scheduled scans and alerts for changes in IP reputation. This proactive approach prevents you from unknowingly using bad proxies. Consistent checks also help maintain business continuity by replacing flagged or banned IPs early.

Here’s a straightforward list to manage reputation checks effectively:

Use multiple databases (AbuseIPDB, IP2Location, Spamhaus).
Perform batch queries for efficiency.
Cross-reference results to reduce false alarms.
Automate regular reputation scans and set alerts.
Remove or quarantine suspicious IPs immediately.

You can integrate these checks into your proxy checker online or SOCKS proxy checker workflow to maintain a clean, trustworthy proxy pool that keeps your operations smooth and safe.

In Conclusion

Using an automated online proxy checker will assist users in verifying the validity of their proxy servers and analyzing them based on various criteria. This ensures efficient setup and secure interaction with web resources, as using reliable proxies encrypts your traffic and protects personal data from potential leaks.

A User-Agent is a string that identifies the user, including details about their device, browser, and operating system. It forms part of the HTTP request sent by a web browser or application to the destination server. This string is automatically included in the request header and supplies the end server with necessary information about the user’s software and device. This enables the server to optimize content delivery or adapt the interface of the web application to suit the user's environment.

The User-Agent plays a crucial role in the digital fingerprint that users leave when they interact online. It is essential in web browsers and applications to provide a seamless user experience.

What data is included in a User-Agent?

To accurately process a user's request, the server requires specific information, which includes:

Browser type and version;
Browser engine;
Device operating system and its version;
Processor architecture;
Device type;
Screen resolution;
Browser or system language settings.

Additionally, browsers may include extra metadata in the User-Agent, such as indications of installed browser extensions.

Let's analyze an example of a User-Agent string and break down its components:

$\"1.png\"$

“Mozilla/5.0” - this part of the string is historical, and included in nearly all browsers. Originally from the Mozilla project that developed Netscape Navigator, it now signifies HTTP protocol compatibility.
“(Windows NT 10.0; Win64; x64)” - this segment indicates that the user's device is running a 64-bit version of Windows 10.
“AppleWebKit/537.36 (KHTML, like Gecko)” - this represents the browser's rendering engine (AppleWebKit) and version (537.36), along with compatibility notes suggesting it behaves like Gecko.
“Chrome/88.0.4324.182” - specifies that the browser making the request is Google Chrome and provides the version number.
“Safari/537.36” - commonly included in various browsers' User-Agents, this part informs the server of additional compatibility requirements for Safari.
“Accept-Language: en-US,en;q=0.9,ru;q=0.8” - indicates the user’s language preferences. “en-US,en;q=0.9” means English is highly preferred.

It's important to note that not all User-Agents will include this exact set of information. The specifics depend on the browser or application's configuration. Moreover, based on what information the User-Agent contains and how it's utilized, there are different types of User-Agents tailored to various needs and privacy levels.

Types of User-Agents

The User-Agent data discussed earlier is employed by web browsers to help servers identify them upon receiving an HTTP request. This allows the server to optimize content display according to the specific browser and device capabilities. Additionally, there are several other types of User-Agents, each tailored for different uses and purposes in the digital environment.

Mobile User-Agents

Mobile User-Agents typically include the name, version, and build of the operating system, along with details about the device and browser being used. These User-Agents are transmitted by mobile devices in requests sent to servers to ensure that the content is adapted to fit the device’s specific limitations and capabilities. For example, a common User-Agent for an Apple mobile device might read as follows:

$\"2.png\"$

This indicates that the device is an iPhone running iOS 15.1, based on Mac OS X, using Safari browser version 15.1.

Additionally, mobile applications such as Instagram or Twitter have their User-Agents, which are sent to servers so that content can be optimized for the specific device and version of the application. For example:

$\"3.png\"$

This line reveals the application name and version, the device model, the operating system version, and language settings. The “Scale/2.00” part indicates that the content is being scaled for display at twice its normal size, adapting it for high-resolution screens.

Bot User-Agents

Various bots, such as web crawlers, have their unique identification strings known as User-Agents. When a server receives a request with a bot's User-Agent, it recognizes that the request is coming from a crawler rather than a regular user. This recognition allows the server to respond appropriately, such as by blocking or limiting the crawler's actions to prevent undue load or scraping that could impact server performance or data privacy. A typical User-Agent for a crawler might look like this:

$\"4.png\"$

This line contains information indicating that the request is from “Bingbot”, the web crawler for Microsoft's Bing search engine, and its version “2.0”. Additionally, it includes a URL where more information about the crawler can be found.

Gaming console User-Agents

User-Agents play a crucial role in identifying devices such as game consoles, allowing web servers to tailor content specifically to their capabilities and interfaces. When a gaming console accesses an online game store, the User-Agent helps the server determine compatible formats, screen resolutions, and other characteristics of the console, enabling it to serve the most appropriate content.

An example of a User-Agent for a game console might look like this:

$\"5.png\"$

From the User-Agent string, we can deduce that the request originated from a game console, specifically the PlayStation 5 made by Sony. The User-Agent also provides details about the console's firmware version, listed as “FirmwareVersion/3.0.1”, and classifies its environment as “Home”. Additionally, “Network/IPv4” signifies that the device connects using the IPv4 network protocol.

User-Agents for web applications and services

This User-Agent is essential for identifying and managing interactions with applications on the server side. Streaming services such as Netflix, Twitch, and YouTube Music utilize web applications that rely on User-Agent data to tailor content delivery and functionality. For instance, a server might use the User-Agent to decide whether to grant access to certain resources or to enable specific features only for the latest versions of the application.

A typical User-Agent string for such an interaction might look like this:

$\"6.png\"$

From this example, it is clear that the request was made from a device running Windows 10, using Chrome browser version 98.0.4758.102. Additionally, the version of the YouTube Music app being used is 4.39.51.

Beyond streaming services, User-Agents are also transmitted to servers by a variety of other web services, devices, and applications, such as search engines, e-books, online checkers, and development environments.

How to find out your User-Agent

Users can discover their User-Agent by using online checkers, such as the “My IP address” tool available on our website. Simply visit the page to view the most current data.

$\"7.png\"$

Another method that works with any browser when using the Google search engine is to type “my user agent” into the search bar. The system will then display the result in the first window.

$\"8en.png\"$

You can also check the User-Agent directly through your browser's settings, as each browser includes specific functionality for this purpose.

How to identify User-Agent in Mozilla Firefox, Google Chrome, Microsoft Edge, Opera, and Safari

In any of these browsers, you can access the necessary data through the developer tools by following these steps:

Press the “F12” key or use the shortcut “Ctrl+Shift+I”. For Safari users, the shortcut is “Cmd+Option+C”.
Once the developer tools window is open, navigate to the console tab. Type the command “navigator.userAgent” into the input field at the bottom, and press Enter. The browser will then display your User-Agent string in the console.\n
$\"9en.png\"$
\n

In the Mozilla Firefox browser, you can also find your User-Agent by following these steps:

Open your browser and click on the icon with three horizontal stripes located in the main window. From the drop-down list, choose “Firefox Help”. In the subsequent menu, select “Troubleshooting Information”.\n
$\"10en.png\"$
\n
On the Troubleshooting Information page, you'll find various details about the application, including the User-Agent.\n

Google developed reCAPTCHA as a CAPTCHA system that attempts to tell if a web request is coming from a human being or a bot. It utilizes far more sophisticated algorithms than simple CAPTCHA verification forms for the analysis of user interactions. Before we dive into how to bypass reCAPTCHA, we need to make it clear what it is and how it works.

Difference Between CAPTCHA and reCAPTCHA

Yes, indeed, traditional CAPTCHAs focus exclusively on text challenges that require users to identify jumbled letters. Conversely, reCAPTCHA offers a more sophisticated solution on the modern relaying authentication framework by integrating image-based CAPTCHAs that utilize real-world visuals.

Here's how a standard CAPTCHA might look:

$\"1.png\"$

Typical reCAPTCHA example:

$\"2.png\"$

Check the box and tick. In some cases, confirmation pop-up windows appear. Such windows might look as follows after site access has been granted.

$\"3.png\"$

reCAPTCHA is designed to prevent automated software from abusing web resources and thus is considered a security feature for websites. Below are some of the ways that reCAPTCHA technology is integrated into web development:

at the registration and login pages in order to block automated sign-up and log-in actions;
at the password recovery pages to block unauthorized password resets;
in feedback and comment sections of pages to block spam form submissions;
in payment and ordering forms so that transactions are secured from robots;
and in APIs, like payment systems, in order to protect against automated inquiries.

reCAPTCHA is important in the World Wide Web, as it aids in the elimination of spam as well as automated activities like bulk feedback or comment submissions and fake account creation. It also helps prevent bot hacking attempts that compromise one's accounts, thereby protecting sensitive information. Important note. You cannot disable CAPTCHA at all but you can effectively bypass it. This article will focus on how to bypass reCAPTCHA and explore this technology further.

How reCAPTCHA Works

So, one can ask: why does Google keep asking if I'm a robot? A unique technique is employed by reCAPTCHA to check for any suspicious activities on a website. Such as how you interact with it by measuring the rate at which you fill in the form fields, mouse movements, time spent on a certain webpage, among many others. It also performs request rate statistical analysis as well as traffic analyses such as the IP of computers accessing the site.

Here’s a breakdown of how reCAPTCHA operates step-by-step:

Once the system detects behavior that fits the description of active user impersonators, reCAPTCHA is set in motion. Users then face the task of “I am not a robot” as a checkbox, which they need to tick.
It assesses the behavior of those who click the checkbox by analyzing the motion of the mouse and other actions like typing, so-called keystroke dynamics.
Next, it subsequently examines the browser and operating system to verify if it is a legitimate interface or an automation tool.
If the preliminary checks yield ambiguous results, reCAPTCHA v2 may put forth an extra hurdle like object recognition in photographs. Nonetheless, image-related tests are eliminated in reCAPTCHA v3.
After you solve the CAPTCHA, you are free to navigate the site. If the task is not completed correctly, the system may allow one to attempt the task again or change the challenge. Blocks are very rare, only occurring where there are extreme security risks or clear attempts to breach the protective measures in place.

reCAPTCHA has integrated algorithms based on machine learning to analyze responses to challenges and perform other statistical comparison analyses relative to the ongoing session, including juxtaposing it with previous sessions.

Reasons for reCAPTCHA Appearance

From analyzing the principles in the functioning of reCAPTCHA alongside the techniques employed in tracing dubious activities on a given site, a number of frequent triggers can be determined. These are fingerprints of a user with identifiable suspicious behavior, an abnormally high count of requests that, from a behavioral perspective, do not seem human, and observed active aggression towards the site. Understanding how it works can help you bypass reCAPTCHA.

Suspicious Browser Fingerprint

A fingerprint is termed as a collection of identification features of a specific browser and the device hosting it. It encompasses the following parameters:

HTTP headers;
screen resolution;
fonts installed on the device;
WebGL or Flash technologies;
IP address.

Upon each request, various types of HTTP headers are sent to the end server and are checked against security systems. Some of these headers include:

User-Agent – gives details about the software or device generating the request;
Referrer – captures the previous webpage that a user visited before transitioning
Set-cookie – cookie captures information about the current session together with preferences and their authorization status;
Accept-language – indicates the preferred languages set by the user.

In the case where bots are used for automating actions on a particular site, the information captured in these headers tends to be incorrect, absent or poorly formatted, making the fingerprint highly suspicious.

Moreover, the security system of the site also studies the person’s geographical location on the basis of the IP assigned to them. In case this area does not correlate with a certain Internet provider or does not match the locations logged in earlier sessions, the site won't let you bypass reCAPTCHA. This technological solution also has the ability to detect IP addresses affiliated with other VPN services and possesses its own “blacklist” of some ranges of IPs. The presence of a CAPTCHA, as you will see, is fundamentally designed to deny access through anonymizers and protect from unauthorized access.

Website Traffic Abuse

Traffic abuse comprises a variety of fraudulent attempts aimed at manipulating website statistics and disrupting the operation of the website. A couple of examples will illustrate traffic abuse:

using specialized proprietary software designed to create fake visits to a webpage;
changing the incoming HTTP request parameters to fabricate the origin of traffic;
using software designed to artificially increase the number of clicks on ads for a specific advertisement;
dropping links to the website through spam comments or on social media or on forums;
redirecting planned traffic to a site from another online resource back to the online resource.

These activities are often done as a means to exploit a resource for self-interest. For example, by rerouting traffic, offenders can surreptitiously capture data, which can later be used for malicious intents, thus maliciously impacting the website’s standing. Furthermore, the use of clickbots can deceptively increase the advertising revenue, either expending the website owner’s finances or unjustly profiting from false clicks.

reCAPTCHA solving mitigates such exploitation in an attempt to limit bot activity. This technology helps curb certain abuses of traffic and makes it harder to carry out automated assaults since bots or scripts invariably fail to identify and complete CAPTCHA tasks. It must be stressed that traffic abuse cannot solely rest on the shoulders of reCAPTCHA – other measures must be in conjunction with analyzing interaction data or deploying behavior-based intrusion detection systems to bolster defenses.

The High Number of Requests

A website can initiate a variety of actions that could severely stress its resources by creating an excessive number of requests or asynchronous tasks. These activities include:

Brute force attacks. These are attempts at gaining access through the guessing of passwords, PINs, or encryption keys. This is a consequence of attempting more than one combination of password through a software program designed specifically to cycle through a range of combinations and select a password until one works
Excessive file downloads. Repeated attempts to download numerous web pages or large files simultaneously can stress the server, causing the web resource to crash and creating significantly slower access to its pages.
Spamming. This involves the flooding of emails, automated comments, feedback forms, and other content with the intention of distributing them en masse. This creates a huge spike in traffic to the server.
Web scraping. This is the automated collecting of data from pages of a particular website through the use of various programs and scripts. Through web scraping, copyright issues, breach of terms of use, and excessive pressure on the servers can arise.

In these situations, to bypass reCAPTCHA, you need to limit the number of requests. By providing tasks that are hard for machines to circumvent, reCAPTCHA prevents further automated attempts, which decreases the number of requests and lessens the burden on the server.

How to Avoid CAPTCHA and ReCAPTCHA

reCAPTCHA technology has its own distinctive features, which provide multiple avenues of bypassing it, one of which is adjusting one’s digital fingerprint. Moreover, there are automated CAPTCHA-solving services that can be embedded into software to complete CAPTCHAs without human intervention. So, how to bypass CAPTCHA verification effectively? The most efficient strategies involve combining several approaches, technological and otherwise, to reduce detection and maintain unobstructed access to targeted web resources.

Google Account Authentication

While using Google services such as Google Search, Google Scholar, or even YouTube, logging into a Google account provides simple methods of how to bypass reCAPTCHA. Google, for instance, implements a bot mitigation system using account data that a client has and the history of their interactions with the system. This technique is likely to work with other remote access services that accept Google credentials, as it relies on the user’s assumed trust associated with its services.

$\"4.png\"$

Yet another attempt to gain access to a web service will trigger reCAPTCHA as a security verification regardless of the user's authenticated state if there is a high volume of traffic submitted or any other unusual patterns present in the data. This guarantee is necessary to verify accuracy and to help strengthen the trust in a web resource.

Using CAPTCHA-solving Services

There are two main ways on how to avoid CAPTCHA. It can be approached from various angles, both manually and automatically. One of the automated approaches is using software that interfaces with one's software, APIs for automating CAPTCHA solutions, and even plugins.

Unlike CAPTCHA services that range from entirely automatic to semi-manual, where AI is used with human verification checking, every service that equips the solving of automated CAPTCHAs comes with its own set of challenges. Undoubtedly the most known service dedicated to automated CAPTCHA bypassing is reCAPTCHA.

2CAPTCHA

$\"5.png\"$

This service operates on the principle of manually solving and can address all current CAPTCHAs from Google, recognizing them on any website. The bypass reCAPTCHA function is facilitated through integration with the service's API.

In the 2CAPTCHA service, payment is based on the number of puzzles solved, with a rate of €1.00 per 1,000 recognized CAPTCHAs. According to the developers of the service, the average time to bypass a standard one is about 6 seconds.

DeathbyCAPTCHA

$\"6.png\"$

DeathbyCAPTCHA can be integrated into web applications or software using an API. This service operates on a hybrid model combining OCR technology and manual human input for CAPTCHA solving. The developer states that the service achieves a solution accuracy of 90 percent and responds in an average time of 8 to 10 seconds. Additionally, there is a guarantee feature; when activated, a CAPTCHA task will be sent to three different workers to ensure the results are correct.

To remove reCAPTCHA, the current pricing of $2.89 per 1,000 correctly solved CAPTCHAs is considered high. It is, however, important to note that users are not charged for tasks that cannot be bypassed.

AZCAPTCHA

$\"7.png\"$

This service is based on artificial intelligence systems. AZCAPTCHA has more than 90% effectiveness solving reCAPTCHA. It has multiple plans, some of which offer unlimited CAPTCHA solving for a specific timeframe as part of the package. It also provides services for $1 per 1000 solved Google CAPTCHAs.

Moreover, AZCAPTCHA has extensions for Chrome and Firefox, which enable you to automate CAPTCHA solving while browsing the internet.

Since Google account login does not guarantee CAPTCHA skips on all sites, and a CAPTCHA-solving service only removes the CAPTCHA after backend systems detect it’s a solved pattern, employing anti-detect browsers and proxy servers could serve as better solutions to bypass reCAPTCHA.

Using Anti-Detect Browsers

Another way to skip CAPTCHA is to use anti-detect solutions. They are specifically designed to prevent tracking of a real user's data online. They are popular in SEO optimization, SMM marketing, e-commerce, and other fields where account creation and management from one workplace are crucial in multitasking.

These tools have advanced functionality designed to automate CAPTCHA interactions while minimizing the possibility of an account being flagged or banned:

Changing the fingerprint. One can modify HTTP headers, devices, and even screen sizes while operating in anti-detection software, which allows changing their digital fingerprint.
Integration with third-party CAPTCHA-solving services. Anti-detect browsers have an API-supported interface that allows integrating external services for automated CAPTCHA solving.
Emulating user behavior. Such browsers provide functionality for automated hand movements and typing simulation, allowing users to appear more natural as they perform automated interactions.
Proxy Integration. Managing a defined set of proxies, distributed with preset rules, can minimize CAPTCHA requests and blocks.

There are five widespread anti-detection solutions that have thoughtful features for customization of one's digital footprint, as well as effective bypass reCAPTCHA strategies.

Dolphin Anty

$\"8.png\"$

The browser features specialized tools for team collaboration, enabling the creation of numerous profiles with unique digital fingerprints for each. Additionally, it supports scripting directly within the interface to automate repetitive tasks, significantly reducing the need for routine manual input.

Dolphin Anty provides access to an extensive database of real fingerprints, greatly minimizing the likelihood of encountering CAPTCHAs. This feature helps prevent the linking of profiles that are created and managed within the same workspace, enhancing the effectiveness and security of operations conducted through the browser.

Multilogin

$\"9.png\"$

This anti-detect solution, along with other advantages, comes with a set of multilogin features aimed at achieving greater privacy and efficiency. One of the many features is a speedy generation of disposable profiles, which are defined as browser profiles that are deleted once and only when Multilogin is closed. These are useful for conducting excessive short-term activities.

Furthermore, it also boasts the ability to automatically turn off dangerous extensions that might leak the real personal data. For example, when a proxy is set, Multilogin automatically retrieves its parameters and sets corresponding values like the languages, the time zone, geolocation, and several others. Moreover, Multilogin has a “CookieRobot” that will go through pages and gather cookies, simplifying the process for the client.

These characteristics allow substantiating a digital fingerprint that can change the interaction with the system and help bypass reCAPTCHA, thus ensuring better and more secure browsing sessions.

GoLogin

$\"10.png\"$

GoLogin has a multitude of distinguishing characteristics, including a web variant that permits you to launch profiles on a cloud server and edit them, as well as an Android mobile application.

The browser includes the “Warpcore” function, which is particularly advantageous for collaboration. With this function, users can operate profiles on different versions of the Orbita and its corresponding engine versions. Warpcore guarantees uniformity across the browser core and mitigates issues where team members utilize different versions of GoLogin and Orbita. This uniformity helps prevent account detection, bypass reCAPTCHA, and prevent blocking of accounts. These features make Warpcore invaluable for sustaining seamless and secure team operations.

AdsPower

$\"11.png\"$

To bypass reCAPTCHA as much as possible, AdsPower provides some helpful features that assist in creating a more realistic fingerprint:

automatic cookie collection by website visitation is done by “Cookie Robot”;
bookmarks can be imported from Google Chrome into bookmarks within every profile or into all of them at once;
while pasting text into the fields, the browser simulates the user performing the actions.

These features help in achieving more effective individual profile settings on the anti-detection browser, which assists greatly in bypassing CAPTCHAs, because, as we mentioned already, you cannot turn off CAPTCHA fully.

Incogniton

$\"12.png\"$

Designed for both a team and an individual, Incogniton comes with two pre-installed browsers: Sun Browser, which runs on Chromium, and Flower Browser, which runs on the Firefox engine. The browser includes a “Cookie Collector” tool that accepts limitless customization of cookie fingerprints.

A standout one is the integrated OCR feature. This allows users to capture images of text and edit the text, showing the advanced functionality and usefulness of the browser.

As with all anti-detect browsers, various capabilities come with varying tariff plans. Let’s look at these deeper through a comparative table.

Using Proxy Servers

A proxy server can help bypass reCAPTCHA by hiding the real IP when sending a request. This is particularly important for data scraping purposes or purchasing items from e-commerce websites. For these purposes, specialized software known as scrapers and sneaker bots is employed. While these programs operate, they make numerous requests to the end servers, which triggers reCAPTCHAs as a protective mechanism.

With proxy support within such software, one can bypass reCAPTCHA or at least minimize CAPTCHA's attention. However, it must be noted that qualitatively working proxies must have rotation – changing IP – or a pool of static servers. In this scenario, a proxy will not be overly monitored through one IP and therefore will not be flagged by the website's security system as suspicious. Thus, two main categories of such servers should be outlined: static and dynamic, followed by a detailed discussion.

Static Proxies Usage to Bypass reCAPTCHA

As previously mentioned, they are assigned IPs that do not change unless altered by the user. They can be rotated manually via specialized software such as sneaker bots, anti-detect browsers, and scrapers. This process requires acquiring a block of IP addresses, having them loaded into the software, and setting a time interval for rotation.

This category includes the following:

datacenter IPv4/IPv6;
ISP.

Note: these two are not equally effective for bypassing CAPTCHAs, which is related to their origins.

The data center ones of type IPv4/IPv6 are assigned by various companies that own private data centers. They are only linked to a certain region, as they have no real ISP associations, making them absent from registries of IP addresses on the internet. During verification of such an IP, security systems check its validity along with its supposed provider and host. If these are unreachable, default CAPTCHA solving is required.

Compared to other types, ISPs have the advantage of being less likely to trigger CAPTCHAs since they are located on the ISP’s servers. That said, excessive request sending from a single IP would likely result in CAPTCHAs being triggered, as the volume of activity would not be typical for an ordinary user.

Dynamic Proxies for Bypassing CAPTCHA

Rotating dynamic ones allow users to customize how dynamically assigned IP addresses are changed, such as time-based or per each new URL request. This proxy removes the bottleneck of having to purchase a pool of IP addresses, as buying a single one or a traffic plan provides access to a dynamically rotating pool of IPs.

This category includes two types:

Residential

Residential ones are those assigned to actual users whose devices are connected to the Internet. Because it is possible to establish the true provider, host, and geolocation of the device, these web resource security systems tend to trust residential ones more. The dynamic nature of the proxies also enables them to bypass the request limit set by web resources on a single IP address, thus lowering the chances of triggering CAPTCHAs.

Mobile

Mobile ones utilize devices with SIM cards. In general, it helps bypass reCAPTCHA due to the way mobile networks operate:

One makes a request for the Internet using a mobile device.
The request gets to the NAT device of the mobile operator’s network.
The NAT device changes the source IP address and port numbers of the request to a public IP and port numbers bound to the mobile operator's network.
The NAT device sends the request to the internet at large using a public IP and port addressable by the general public.
When some data is sent back from the server, the NAT device in the mobile operator’s local network shall receive the response and, with port info, enable them to reroute the response to the mobile subscriber that actually requested it.

NAT means Network Address Translation. It refers to a feature in mobile networks where a private computer network IP in a public domain is transformed or changed to a valid and accepted computer networking IP. NAT helps in the management of mobile broadband. It allows numerous devices employing the mobile network to make phone calls, to share a single mobile IP address, and to still make use of the private IP address system. This will increase the available IPv4 addresses, which indirectly prolongs their availability.

Because of this operational principle, large amounts of requests coming from a singular mobile IP address are treated as normal activity and are not flagged as suspicious by web security systems.

Therefore, mobile proxies come out as the most potent means for bypassing reCAPTCHA, especially for automated actions or for resources that are heavily guarded. They are best used in conjunction with anti-detect browsers, sneakerbots, and parsers since they do not require additional services for solving CAPTCHAs.

7 Practical Methods to Bypass Recaptcha

You’ll learn how to bypass reCAPTCHA using proven techniques that reduce triggering CAPTCHA challenges. Follow these practical steps closely.

Avoid Hidden Traps

CAPTCHA systems use honeypots – hidden traps to catch bots. These often appear as invisible form fields or fake page elements that bots mistakenly interact with. Never interact with hidden DOM elements. Instead, scan pages to identify these traps before scraping. Always respect robots.txt and website terms of service. Avoid using proxy IPs flagged for suspicious activity, and don’t scrape from public Wi-Fi networks that are prone to blacklists. Tools integrated with Proxy-Seller’s services can help you detect honeypots.

Use Real Headers

Setting realistic HTTP headers helps mimic genuine users. Fake headers like “python-requests/x.x” or “HeadlessChrome” immediately raise red flags. Avoid headers that are missing key fields such as Accept-Language or Connection. Use browser devtools to inspect headers from popular browsers. Save these header templates and cycle through them. Libraries like fake_useragent can assist with this in Python. This simple step is essential for a successful Google reCAPTCHA bypass.

Rotate Headers

To dodge fingerprinting, rotate key headers like User-Agent, Sec-Ch-Ua-Platform, Referer, Accept-Language, and Cookies. Yet, keep headers consistent within a session to avoid mismatch detection. Tools like Puppeteer-extra-plugin-stealth, Selenium with custom header injection, or Python’s requests session objects allow smooth header rotation. Rotating headers makes bot detection much harder, improving your chances of bypassing reCAPTCHA v3.

Use Rotating Proxies

IP rotation is critical. You can use sticky sessions (same IP for multiple requests) or rotate proxies after every request/batch. Free proxies are unreliable. Premium residential proxies perform better – offering geo-targeting and clean IP reputations. Proxy-Seller provides over 20 million rotating residential IPs worldwide with geo-targeting. Their proxies support sticky sessions and request- and time-based rotation and offer SOCKS5 and HTTP(S) options. Proxy-Seller’s IP pools clear CAPTCHA triggers caused by static or datacenter IPs to ensure smoother scraping. Limit your requests per IP and concurrency to avoid rate limits.

Implement Headless Browsers

Use headless browsers like Selenium, Puppeteer, or Playwright to run JavaScript-heavy pages and simulate user actions. These tools help bypass CAPTCHA types relying on JS challenges by simulating mouse movements, clicks, scrolling, typing delays, and network conditions. However, basic headless mode reveals automation via navigator.webdriver. Use stealth plugins such as Selenium Stealth or Puppeteer Stealth to hide these signs. Running realistic browser interactions allows effective Google reCAPTCHA bypass in dynamic environments.

Disable Automation Indicators

Bots expose themselves via flags like navigator.webdriver or altered JavaScript APIs. Use plugins or custom scripts to hide or spoof these indicators. This includes faking browser plugins, languages, user media, WebGL, and canvas fingerprints. You can employ the Chrome DevTools Protocol (CDP) to overwrite these properties. This step is vital to bypass reCAPTCHA v3 without raising alarms.

Make Your Scraper Look Like a Real User

Mimic human behavior by adding random mouse movements, scrolling at variable speeds, clicking with delays, and typing naturally. Randomize action sequences and intervals to avoid predictable patterns. Use exponential backoff when hitting CAPTCHAs or error responses. Running headless browsers to execute JS challenges further helps. Libraries like pyautogui or Robot Framework assist with input automation. Continuously log and analyze your behavior to keep improving your reCAPTCHA bypass success.

Repeatedly failing CAPTCHA without a fallback causes blocked access.	Combine avoidance methods with on-demand solving only as a last resort.

By avoiding these pitfalls and applying the steps above, you’ll master how to bypass reCAPTCHA and lower CAPTCHA encounter rates effectively.

Conclusion

If you want to bypass reCAPTCHA for the purpose of multi-accounting or scraping the web in an automated fashion, it often necessitates employing multiple techniques. The most sensible way of doing so is utilizing an anti-detect browser paired with dynamic proxies. This configuration makes it possible to spoof the entire digital fingerprint and emulate numerous users interacting with a web resource to bypass detection patterns associated with reCAPTCHA.

Proxy servers can be categorized by many factors: their purpose, how they are used, their level of anonymity, and more. One of the key distinctions is based on where the intermediate server sits in the network path. From this perspective, we differentiate between forward and reverse types.

Understanding how these two models differ is critical for companies that rely on network technologies in commercial products and infrastructure. The choice of solution directly affects web service performance, data protection, and the resilience of the overall architecture to external threats. This article explains what a reverse proxy is, which tasks it solves, and how it differs from a forward proxy.

How reverse proxies work

A reverse proxy is a component of network infrastructure whose primary role is to accept incoming requests, process them according to predefined logic, and safely route them to the target servers. It offloads the infrastructure and adds an extra control and protection layer at the network perimeter.

A typical reverse proxy workflow looks like this:

A user initiates a request, for example by opening a web page.
The request is sent to the reverse proxy.
The intermediate server forwards the request to the origin server that hosts the required data.
The origin server returns a response to the reverse proxy, which then relays it to the user.

In this model, the reverse proxy sits between the client (for example, a browser or an application) and the origin server, and hides the real IP address of the latter.

Use cases of reverse proxies

Considering the location of reverse proxies, they can be effectively used in several scenarios:

Distributing incoming requests across multiple servers in a cluster to balance the load, for example with NGINX or HAProxy.
Caching static content (images, style sheets, scripts) to reduce response time, as in solutions such as Varnish Cache.
Improving web application performance through data compression, reducing the number of HTTP requests, and performing pre-processing of responses — an approach used in NGINX and Varnish, where compression and caching speed up page loading and reduce load on the origin server.
Protecting the origin from DDoS attacks by filtering suspicious traffic, analyzing request frequency, and automatically blocking malicious activity.
Masking the IP address of the origin server to add a further protection layer, as in services like Akamai and Fastly, which hide the internal network infrastructure.
Redirecting part of the traffic to healthy backup servers to maintain fault tolerance during failures or maintenance.

From these traditional functions, it's clear that a reverse proxy plays a critical role in ensuring the stable operation of the end server and in safeguarding it from various threats.

What are forward proxies and what are they used for

Reverse and forward proxies serve different roles based on their location and functions. To understand the difference, let's examine how forward proxies operate:

The user sets up a proxy on their device or within their software, and, for example, opens a page in the browser.
When accessing a web resource, the request is sent not from the user’s real IP address but from the address of the intermediate server.
The final server receives the request from the proxy rather than directly from the user.
The intermediate server returns the response to the client.

In this case, the solution sits between the user and the web resource, relaying requests and responses between them.

It's important to recognize that forward proxies vary in their levels of anonymity, which classifies them into transparent and anonymous proxies. Transparent proxies do not conceal the user’s original IP address nor the fact that a proxy is being used, and they are typically employed for routing requests.

Anonymous proxies, on the other hand, completely mask the user’s IP address and obscure the use of a proxy. They are particularly useful for several purposes:

Testing regional availability and localization by emulating traffic from target regions to verify UI behavior, payment systems, and local services.
Using them together with antidetect browsers to isolate environments and distribute IP addresses when managing multiple accounts on social networks, marketplaces, and online platforms.
Automating actions in online services with distributed requests that simulate natural user activity for data collection, monitoring, and process management without overloading systems or triggering platform safeguards.
Protecting user traffic from interception and other malicious activities.

Forward proxies can be hosted in various locations such as data centers, ISP servers, or mobile devices, each providing different levels of accessibility and security.

Differences between reverse proxies and forward proxies

The table below summarizes the key differences between reverse and forward solutions:

\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n

Characteristic	Reverse proxies (server side)	Forward proxies (client side)
Location	On the server side, in front of origin servers	On the client side – configured on user devices or at the organization’s network edge
Traffic direction	Handle incoming requests to the server	Handle outgoing traffic from the client
Traffic management	Filtering, load balancing, protection, caching	Masking, filtering, caching
IP rotation	Possible but not mandatory	Commonly supported
Configuration process	Deployed and maintained by system administrators or DevOps engineers at the infrastructure level	Configured by end users through software settings or via corporate network policies
Primary use cases	Protecting infrastructure from DDoS attacks, optimizing server performance, caching content (for example, Cloudflare, NGINX)	Web scraping and parsing, managing accounts on social networks, automating business processes, testing content by region, SERM and SERP monitoring

The difference between these two types lies not only in how they process requests but also in their purpose. Forward proxies focus on outgoing traffic: they mask user IP addresses, support IP rotation, and provide controlled access to resources. Reverse solutions, on the other hand, manage and filter incoming traffic, protecting and optimizing the operation of origin servers.

FAQ

Can forward and reverse proxies be used together?

Yes. Large infrastructures often combine both: reverse proxies protect servers and balance incoming traffic, while forward proxies handle outgoing data in a controlled and distributed way.

Which is more expensive — forward or reverse proxies?

Reverse proxies are usually more expensive because they require server resources, infrastructure configuration, and ongoing maintenance by DevOps or system engineers. Forward proxies are often cheaper, as they are provided as ready-made services and do not require deployment on the client side.

Can proxies be combined with WAF (Web Application Firewall) systems?

Yes. Reverse proxies are frequently integrated with WAF solutions to block malicious requests and SQL injections at the perimeter before they reach the application. Forward proxies can also be used together with WAF or IDS/IPS systems to analyze outgoing traffic, control user requests, and prevent data leaks from a corporate network.

All devices acting as proxy servers are integrated into a single network. To facilitate efficient interaction among these devices, they are segmented into distinct groups known as proxy server subnets. Each subnet consists of a common range of IP addresses, and importantly, all subnets are isolated from one another. This segmentation is crucial for traffic control, performance optimization, and simplifying network management for administrators. Given this architecture, we will next explore the fundamentals and principles of subnets, as well as their impact on the functionality of proxy servers.

Public and private subnets

Based on how subnets are utilized on the Internet, there are two primary types: public and private. The choice between them depends on the user's objectives.

Public subnets are open for communication with all other networks on the Internet. These subnets typically host web servers, mail servers, cloud services, and other resources that require external access.

Private subnets, on the other hand, are either not accessible from the Internet or have limited accessibility based on their configuration. They are commonly employed within corporate networks to control access and enhance security for data exchanges between devices on the network. Private subnets are designed to connect specific computers, ensuring data confidentiality and eliminating exposure to \"neighbors\" within the subnet.

The setup of a private subnet often involves cloud services such as Microsoft Azure or Google Cloud Platform (GCP), alongside various network hardware like routers, firewalls, and network management devices.

It's crucial to recognize that the type of subnet also plays a significant role when using proxy servers. Typically, purchasing a proxy server provides the user with an IP address from a public network, allowing unrestricted access to various web resources. Conversely, proxy servers operating from private subnets may have restricted Internet communication, which is why they are specifically configured within corporate networks for particular tasks.

Defining the subnet mask of a proxy server

To gain a deeper understanding of subnets, it is essential to learn about the concept of a proxy server subnet mask. An IP address is divided into two parts: the network address, which is common to all devices on that network, and the host address, which identifies a specific device within that network. The subnet mask is a parameter that specifies which part of the IP address represents the network and which part represents the host. This distinction is crucial for devices to determine the correct recipient of data within the network.

The subnet mask is typically expressed in dot-decimal notation, which consists of four blocks of numbers separated by dots, such as 255.255.255.0. When this mask is applied to an IP address, the numbers preceding the zeros in the mask define the subnet, and the zeros designate the host portion. Thus, for IP addresses within the same subnet, the first three blocks of numbers will remain constant, and only the last block will vary, distinguishing one host from another. An example of how this subnet structure looks can be seen in the diagram below:

$\"1EN.png\"$

How to identify a subnet

Understanding what a subnet mask is and its purpose simplifies the process of identifying a subnet. To do this, you need to know your IP address and your subnet mask. Let's explore how you can retrieve this information across different operating systems.

Identifying a subnet in Windows OS

On Windows, you can obtain your IP address and subnet mask by following these steps:

Open the command line by pressing the key combination “Win + R”. In the dialog box that appears, type “cmd” and press “Enter”.\n
$\"2EN.png\"$
\n
Once the command line window opens, type the command “ipconfig” and press “Enter”.\n
$\"3EN.png\"$
\n
The output will display your network information. Look for the “IPv4 Address” to find your IP address and the subsequent line will show your subnet mask.\n
$\"4EN.png\"$
\n

In the example provided in the screenshot, the subnet is identified as 192.168.0. The number in the last block is what differentiates individual devices on the network, representing the specific computer’s address within that subnet.

How to determine the subnet of an IP address in MacOS

To check the subnet mask on an Apple device through the system settings, follow these steps:

Click on the Apple logo located at the top of the desktop and choose “System Settings” from the dropdown menu.\n
$\"5EN.png\"$
\n
Navigate to the “Network” section and select your active network connection. The window that opens will display your current IP address and subnet mask.\n
$\"6EN.png\"$
\n

For example, if the subnet mask shown in the screenshot is the standard 255.255.255.0, then the subnet number would be 192.168.1.

How to find the subnet mask on Linux

In the Linux operating system, you can determine the subnet mask and IP address using the terminal by following these steps:

Open a terminal window using the search bar.\n
$\"7.png\"$
\n
Type the command “ifconfig” into the command line and press “Enter”.\n
$\"8.png\"$
\n
The output will display various pieces of network information, including the IP address. From this, you can identify the subnet. In this case, the subnet for the IP address might be identified as 192.168.15, based on the provided details.\n
$\"9.png\"$
\n

It's important to understand that this method only checks the subnet mask of the native IP address of the user's computer. You cannot calculate a subnet mask from an IP address using online checkers, nor can you initially obtain a proxy with a known subnet mask. Therefore, users should verify this information with their proxy provider or consider the first three blocks of numbers in the IP address list when purchasing a proxy. If they match, then all addresses belong to the same subnet, which could potentially influence the operation of the proxy server.

The impact of the subnet on proxy servers

Grouping IP addresses into the same subnet can lead to both advantageous and detrimental outcomes. Here are the benefits of organizing IP addresses into subnets:

Establishing a subnet simplifies the implementation of various security measures that safeguard IP addresses from external threats;
Subnetting enables the optimization of routing and traffic management, enhancing the performance of a specific proxy server and the availability of its resources;
Subnets make the management and administration of IP addresses easier, allowing for swift maintenance when needed;
Utilizing separate subnets can isolate issues, reducing the impact of failures on other network segments.

There are additional ways in which subnets impact proxies, particularly related to user activities on IP addresses within the same subnet and how web security systems respond.

When a security system detects suspicious activities, such as spamming or excessive request sending from an IP address, it may impose restrictions or blocks on that specific IP or potentially the entire subnet. The possible adverse outcomes for users of proxy servers in such scenarios include:

Individual IP addresses may be blocked from accessing certain web services and resources;
The entire subnet may be blacklisted, preventing all associated IP addresses from accessing network resources;
The reputation of the entire subnet may be diminished, negatively affecting all the IP addresses linked to it.

Additionally, regional restrictions may be applied to subnets. If a subnet is associated with a specific geographical location, this can restrict access to certain resources for the IP addresses within that subnet, which adversely affects the ability to bypass blocks and filters.

Problems may also emerge from the activities of an individual user or other users sharing the same subnet. Generally, web resources are cautious about implementing drastic measures such as blocking, to avoid negatively impacting users who have not engaged in any prohibited actions. However, certain types of sites, such as bookmakers, might impose blocks more frequently. This is because clients of these services often use a pool of IP addresses from the same subnet to engage in activities that contravene the site's policies.

How to avoid negative impacts of subnets on proxy

The concerns raised above prompt users to question how they can maintain their isolation and anonymity when using an IP address from a common subnet. There are various methods to prevent specific IP addresses from being associated with activities on a subnet, and the choice of method will depend on the type of proxy needed. Here are the four main types of proxy servers:

Server IPv4 and IPv6 proxies - these are IP addresses located in data centers.
ISP proxy - these are IP addresses situated on the servers of Internet service providers;
Mobile proxies - these are located on mobile devices and owned by mobile operators;
Residential proxies - these are located on the computers of real users.

Next, we will explore the primary strategies to shield your IP addresses from the effects associated with the subnet, focusing on the different types of proxies available.

Choose proxy servers from different subnets

When purchasing several datacenter or ISP proxy servers, a user may end up with IP addresses from the same subnet, as these IPs are static and part of a specific network infrastructure. Consequently, if a web resource decides to block the entire subnet, all of the user's IP addresses could become inoperable. To avoid this, it is crucial to effectively utilize proxy subnets by selecting IP addresses from different subnets. This approach is particularly important when purchasing a pool of IP addresses and can be implemented in the following ways:

Request IP addresses from different subnets individually. Contact the customer service of your chosen proxy provider and specifically request IPs from various subnets;
Purchase from large proxy providers. Bigger providers often have extensive pools of IP addresses and are likely to issue IPs from different subnets;
Opt for proxies from large and popular locations. These areas tend to offer a wider variety of subnets compared to smaller countries.

Using IP addresses from different subnets is advantageous for activities such as web scraping, multi-accounting, and e-commerce operations. In these cases, ISP proxies are generally more favorable than IPv4 and IPv6 proxies, as they are associated with internet providers and are less frequently blocked by web resources. However, for short-term tasks where cost is a concern, data center proxies might be a suitable choice since they are the most economical option.

Select exclusively private proxy server subnets

For certain applications, employing private subnets is an appropriate option. These are configured using dedicated hardware and a subnet mask, which specifies the maximum number of computers that can connect. Private subnets are particularly relevant for corporations and enterprises of various sizes, enabling secure data exchanges within specific departments, offices, or branches.

Integrating proxy servers in this scenario allows organizations to enhance control over employee access to web resources and to manage traffic more effectively. However, locating a proxy server that operates within a private subnet can be challenging. One solution is to establish your proxy server, provided there is access to a private subnet.

Moreover, compared to the use of public proxy servers, this method is more complex and generally suitable for organizations that possess the necessary financial resources for implementation. For individual users with personal proxy needs, this approach might not be feasible. For such users, exploring other proxy solutions would be more beneficial.

Use residential or mobile proxy types

When selecting residential or mobile proxies, the specific subnet they belong to is generally irrelevant due to the dynamic nature of these IP addresses. Both types of IP addresses change periodically, which can be configured based on user preferences.

When opting for residential proxies, users can specify several parameters to tailor the service to their needs, including:

Country;
City;
Internet Service Provider.

Based on these choices, the proxy provider will issue a pool of IP addresses from computers that are actively distributing traffic at the time of the user's request. The pricing model for residential proxies is typically based on the amount of traffic used rather than the number of IP addresses, as these proxies are associated with real users' connections that regularly rotate IP addresses. This frequent change in IP addresses means they are rarely blocked, making the specific subnet of lesser importance.

For mobile proxies, the selection process allows users to choose:

Mobile network operator;
Communication standard (e.g., 3G, 4G, 5G);
Country.

Upon purchasing a mobile proxy, users establish the principles and timing for IP address changes. They are then assigned an IP address from the mobile operator's pool, which rotates according to the predefined settings. Due to the unique architecture of mobile networks, mobile IP addresses are seldom blocked, negating the need for users to concern themselves with the subnets these IPs belong to. This flexibility makes mobile proxies particularly useful for users requiring reliable and uninterrupted access to the internet without the typical constraints associated with fixed IP addresses.

These types of proxy servers are highly favored by users seeking to circumvent blockages and restrictions associated with proxy server subnets, making them an ideal choice for various applications, including:

Web scraping - employing bots for automated data collection from websites;
Multi-accounting - creating multiple accounts on social networks and other web services to manage several profiles simultaneously;
E-commerce - utilizing bots for automated purchasing and account registrations on marketplace platforms.

In conclusion, it's important to recognize that subnets are a key factor influencing the functionality and reliability of proxy servers, particularly affecting IPv4 and IPv6 data center proxies. The tendency of web resources to block an entire subnet in response to suspicious or malicious activity from even a single IP address within that subnet is a significant vulnerability. In contrast, mobile and residential proxies are generally accorded a higher level of trust by web resource security systems due to their dynamic nature and different operational principles. Consequently, for critical applications, users are advised to focus not just on subnets but on the type of proxy they are selecting. Making informed choices based on the specific goals of their activities can greatly enhance the effectiveness of the proxy server.

Proxy server technology enables users to conceal their real IP addresses, bypass regional blocks, and circumvent access restrictions to various resources. Effective anonymity and privacy are typically achieved through the use of anonymous proxies that robustly conceal users' actual data. One crucial aspect of proxy anonymity is the level of data encryption, which helps classify proxies into transparent and anonymous types.

A transparent proxy is a type of server that does not hide the user’s real IP address or the fact of its use. It is commonly utilized by developers for testing websites or for redirecting requests. However, transparent proxies do not provide internet anonymity.

An anonymous or elite proxy, on the other hand, is a server that conceals both the user’s real IP address and the use of an intermediary server. These proxies are often rented from providers and are exclusively used by one user throughout the rental period.

When the rental period expires, the IP address is transferred to another buyer. This transition might occur immediately or after a “freeze” period intended to lift any restrictions or blocks incurred by the previous user's actions. However, IP addresses do not become entirely “clean” after such a period. Clean proxies refer to IP addresses that have never been used before, ensuring they are not blocked due to suspicious activities by previous users. The buyer of a clean IP address becomes its first owner. Next, let's explore whether clean proxies truly exist and what alternatives to anonymous proxies are available.

Are there “clean” IPv4 proxies?

Currently, all IPv4 proxies available for purchase have been previously utilized. There have been no “clean” IPv4 proxies since 2015, which is when ARIN, the American organization responsible for distributing IPv4 addresses, declared that their free pools of IP addresses were exhausted. This scarcity of unused IP addresses is due to the limitations inherent in their format.

IPv4 proxies use a 32-bit address format, represented by four numbers ranging from 0 to 255, separated by periods. An example of such an IP address is 192.168.176.180. This format allows for the creation of 4,294,967,296 unique IP addresses. However, not all of these are available for use as proxies because they serve other essential functions, such as:

Private networks;
Multicast transmissions;
Identification and management of network devices.

Consequently, the actual number of addresses that can be assigned for proxy use is significantly lower than the total possible, making it impossible to find an unused proxy in this format.

Features of “clean” IPv6 proxies

IPv6 is a newer version of the Internet protocol developed to address the shortage of unique IP addresses available under IPv4. The defining characteristic of IPv6 proxies is their 128-bit address format, which includes alphanumeric values separated by colons. Clean IPv6 IP addresses are continually emerging due to the expansive address space provided by this format. Technically, every time a new local network is created or a new device connects to the Internet, it could be assigned a previously unused IP address.

An example of an IPv6 address is: 2001:0db8:85a3:0000:0000:8a2e:0370:7334.

While IPv6 enables the availability of clean proxies, its adoption comes with challenges, primarily due to limited compatibility with many existing web resources. Utilizing an IPv6 proxy is most beneficial when accessing major platforms and web services like Google, Facebook, YouTube, LinkedIn, Amazon Web Services, and Netflix, which have better support for the newer protocol.

As more organizations continue to adopt IPv6 to scale their online services, the list of compatible resources is expanding. However, before investing in an IPv6 proxy, it's crucial to verify that the resource you plan to interact with supports this format.

Alternatives to “clean” proxies

IP addresses can have different affiliations, leading to several types of proxies:

Datacenter proxy: located in private data centers;
ISP: owned by Internet providers and located on their servers;
Mobile: owned by mobile operators and located on mobile devices;
Residential: owned by Internet providers, but located on the PCs of real users.

In theory, each type of proxy can support both IPv4 and IPv6 formats and provide “clean” IP addresses. However, the transition of Internet providers and mobile operators to the new IPv6 format is progressing slowly. As a result, not all providers have sufficient IPv6 addresses to offer as proxies.

Currently, most IPv6 IP addresses available for purchase as proxies are located in data centers. These data center proxies often have a low trust factor, an indicator assessed by web resource security systems. Datacenter IP addresses might be blocked or require captcha solutions, even if they are “clean”, because security systems do not view their origin as reliable. Furthermore, web resources might block them based on their address range, potentially affecting even “clean” proxies if they share a range with other blocked addresses.

Given these challenges, when searching for a reliable proxy server, it is advisable to consider proxies not just for their “clean” status but for their likelihood of not being blocked and their association with real providers, even if they use the IPv4 format. These are typically mobile and residential proxies, which we will explore in more detail below.

Mobile proxies

A mobile proxy operates using a SIM card from a mobile operator and has a dynamic IP address. The architecture of mobile networks involves a limited number of IP addresses available to clients. To use these resources effectively, IP addresses are continuously redistributed among active devices—a process known as rotation. This mechanism ensures that the IP address is dynamic, being assigned to a user as long as they are within the network coverage area. When a mobile device connects to a different network, its IP address changes, and the previous one is reassigned to another user.

Due to this dynamic nature, 4g proxies cannot be “clean”. However, they are typically not subject to blocking because blocking one user could potentially block thousands of other users who might be assigned that IP address in the future. This characteristic ensures that the actions of previous IP holders do not affect subsequent users.

Additional features of mobile proxies include:

Tariff plans that offer unlimited traffic.
Two types of IP address rotation: based on link or specific time periods.
Access to a pool of tens of thousands of addresses from mobile operators in a specific location, within which rotation occurs.

These characteristics make mobile proxies particularly effective for tasks such as automated testing, mass account creation, traffic arbitrage, and activities related to SEO and SMM.

Residential proxies

A residential proxy server utilizes the internet connection of a real user's device, typically tied to a specific physical address, which significantly boosts its trust factor. Users of residential proxies access the internet using the IP address of a home network user, which web security systems recognize as originating from a legitimate provider, hence they typically do not block these IPs. Like mobile proxies, residential proxies are not “clean” since they are already assigned to real people, and they are dynamic. Key features of residential proxies include:

The use of a residential proxy is virtually undetectable because the IP address belongs to an actual user.
They offer extensive geographic coverage due to the nature of their distribution.
They allow for the setup of a proxy pool from a specific region, where rotating residential proxies can change IPs over time.

Residential proxies are particularly valuable for applications requiring high trust levels, such as using automation software like sneaker bots.

It is also important to note that ISP proxies fall under the category of residential proxies. Compared to data center proxies, ISP proxies have a higher trust factor since they are associated with internet providers. However, the likelihood of being blocked or triggering a captcha depends on the user's activities, as these addresses are static.

In conclusion, merely being unused by others does not inherently guarantee the reliability of an IP address. Truly “clean” IP addresses are mostly IPv6, which are often located in data centers and generally have a lower trust factor, leading to potential blocks and restrictions by web security systems. Therefore, a more reliable measure of a proxy's efficacy is its affiliation and operating principle, making residential and mobile proxies robust alternatives for secure and trusted internet activities. If you need reliable pools for these use cases, Proxyseller can be used as a source of mobile or residential options depending on your task

Private proxy serves as a gateway toward restricted resources. When it comes to managing networks, knowing how to test the speed and performance of them is crucial. This comprehensive guide goes into detail through the process of proxy ping measuring which facilitates users to evaluate the speed, stability, and performance of it without offering any sophisticated technical expertise.

How to Ping Through Proxy Servers?

To start off, let’s answer the question: what is proxy ping? It refers to the time it would take for data to travel to the intended server or resource and return back. Normally it is measured in RTC or round-trip time. In terms of speed, it is measured in milliseconds (ms) with lower ms being better.

Such a process can seem complex, but it can be simplified with the right tools and approach. We're gonna show you in detail different methods, one involves setting up the whole system and the second one is for just the browser.

Using Command Line – Step-by-Step Guide

So let’s start with how to ping proxy servers using the command line. This approach allows you to view more sophisticated details about your connections. First and foremost, you need to set up a system-wide setup. For this you can use the Proxifier app, here you can find setup guide.

To launch the command line, simply press the “Win + R” keys simultaneously. This will open a dialogue box. In that box, write down the word ”cmd” and click the “OK” button, alternatively hit the Enter key.\n
$\"1.png\"$
\n
Now type in ”ping [target resource, for example, www.google.com and hit “Enter” immediately after to start the process of ping over proxy.\n
$\"2.png\"$
\n
You'll get results, showing response time in “ms” and lost packets if there are any.\n
$\"3.png\"$
\n

If you notice packet loss from the proxy ping statistics or round-trip is too high, the connection is not ideal and needs upgrading. 110 ms or more is considered a high value and is not suited for gamers, or anyone else who spends a lot of time online.

How to Measure Proxy Ping Time and Latency With Web Tools

You can also check your internet connection speed using an online testing service. First, you need to set up a proxy for the browser or just use the previous method with Proxifier, it can also be used for specific browser setup. In case it doesn’t work for you, it’s recommended to use extensions, there are a lot of them, and they are working pretty the same way. Here you can find TOP of them and choose one.

When this is done, visit the ping checker tool page and type in the domain name or IP address you would like to test. Alternatively, you can opt to “Paste my IP address” and your IP address will be filled in for you.\n
$\"4.png\"$
\n
Choose the option from the list that will perform the ping towards the specified host or IP.\n
$\"5.png\"$
\n
Specify how many packets you wish to deploy.\n
$\"6.png\"$
\n
Press “Ping IP” when you are ready to start the test.\n
$\"7.png\"$
\n
Test results will be shown within one minute. However, depending on the amount of test packets determined, this may be longer or shorter. A detailed evaluation of the test results will be given below.\n
$\"8.png\"$
\n

In order to evaluate the effectiveness of the new connection, check your home IP address and the new IP address. Generally, using them improves response times by decreasing pings because the signal is sent through more dependable networks.

Why Measure Proxy Ping and Speed?

Issues significantly affect user experience, which is why they are best checked for high latency and slow speed at all times. These problems can interfere with browsing, gaming, or even video conferencing which require incredibly low latency. Here is why you need to check ping, proxy speed and a little advice on how to improve it.

Proxy Ping Time and Server Performance

Proxy ping time is a critical metric for assessing the efficiency of a server. To manage and improve it, consider these focused strategies:

Constantly monitor your response times with the aid of testing tools.
Use proxies that have optimized routing to lower latency. You can perform traceroute using web tools.
Having a proxy nearer to the target server will help lower the response time.
Check your local networking hardware to ensure they are set-up to provide fast data transfering.

These suggestions, if implemented, can increase the caching efficiency of your server making it more responsive.

Troubleshooting Proxy Latency and Jitter

In case you experience latency or jitter with a server, the following suggestions should help you improve the quality overall:

Make sure that the connection is set up correctly for what you want to do with it. Some people may need to switch the type being used, such as an HTTP or SOCKS. A different type may perform better depending upon the environment one is working in. HTTP – for browsers mostly, Socks5 – for any kind of software or apps.
Choose the right location. It should be closer to the targeted server so it can be reached quickly. Latency is a function of distance.
Use a reliable provider. Indeed, not all servers are equal in performance. Check provider reviews and test different proxies to determine which has the best performance for your needs.
Limit the load. Try to limit the number of applications and devices using the same server at the same time. Having too many applications can unnecessarily overload it and increase latitude or jitter.
Check for network congestion. Use network monitoring tools to check if the increased latency or jitter is due to network congestion. If congestion is the issue, try accessing the service at different times when the load may be lower.
Contact support. If everything mentioned above has been tried and the problem still persists, reach out to the provider’s support team. They may have helpful information and are likely able to change the server configuration to better meet the connection requirements.

These steps can significantly reduce ping with proxy and jitter, allowing you to connect through your server more effectively and effortlessly.

How the Proxy Type Affects Ping and Speed

The proxy type directly influences latency (ping) and throughput, because each proxy category uses a different network path and infrastructure.

Datacenter IPv4 / IPv6 proxy usually delivers the lowest ping and highest speed. It runs on high-performance servers with direct uplinks, which minimizes latency. This makes it suitable for technical tasks, automation, and bulk operations where trust level is secondary.
ISP proxy offers a good balance between speed and stability. Its ping is typically slightly higher than pure datacenter proxies, but still low and consistent. Since it is routed through real ISPs, they provide predictable performance suitable for long sessions, apps, and APIs.
Residential proxy generally has higher ping and lower average speed. Traffic passes through real household connections, which adds latency and depends on the end user’s network quality. This trade-off is expected in exchange for higher trust and better acceptance by target platforms.
Mobile proxy usually shows the highest ping and the most variable speed. Mobile carrier networks introduce additional routing layers, NAT, and congestion, especially during peak hours. However, this is compensated by a very high trust level and strong resistance to blocks.

Best Tools to Check Proxy Ping and Speed

There are a lot of different web tools nowadays. When it comes to monitoring and diagnosing performance, certain ones stand out.

Kill Ping Proxy Server – Does It Really Help?

For categories of users like gamers, optimizing ping is crucial. One way to achieve this is by using traffic routing services to enhance the gaming connection. Previously, such services were provided by platforms like “Kill Ping Proxy Server”, but it is no longer operational. Overall, a more reliable approach is to comprehensively assess the network's condition yourself. Below is a list of tools to help you with this.

Proxy Analyzer Tools for Better Connectivity

You’ll need powerful analytic tools for proxy effectiveness which are critical to big businesses that own numerous of them. They assist in identifying low latency proxies by monitoring latency.

The IP address ping check tool helps for free to find out in a few moments and clicks the level of access quality to the resource specified by users from the required countries. Capture the time when the attempt to connect is made and the time when a response is received. Check the created channel for stability.
Online IP Trace is a diagnosis tool that has the capability to show the status of all the routers that are intermediate to the end node. Tracing checks for packet loss on the Internet. It can construct the route from a specified server to the final host or IP address and display it. Tracing IP will assist in determining the time that can be said to be delayed in getting from a certain point A to a point B further along a specified route.
Moreover, if you have to conduct a speed test, you can use this tool that also displays how long it took to access a particular web resource in question.

All of the specified above solutions have distinct features that satisfy different requirements ranging from real-time analytics to advanced traffic analysis while addressing the needs of effective network management.

Proxy Ping: Final Thoughts

Tracking your ping of proxy and speed on a regular basis can circumvent potential issues beforehand, ensuring your network runs smoothly. Moreover, adjusting the configuration, location selection, and incorporating sophisticated monitoring and troubleshooting programs aids in maintaining an optimal proxy balance. Regular performance monitoring and modification of the network system is essential in enhancing network efficiency – letting users have fast and seamless online experiences.

Do Not Track (DNT) is a setting found in web browsers and a software tool designed to prevent tracking of users' online activities. When activated, this feature sends requests to websites, informing them of the user's preference regarding tracking for analytics and personalization.

In some cases, it may be necessary to disable this feature. For example, to improve traffic, collect analytics data, or gather data for analytical metrics. If a website follows the “DNT” request, the data it collects may be incomplete or distorted. Below, we'll explore how to disable this feature in the most popular browsers.

How Do Not Track Works

The “Do Not Track” feature works by sending a special HTTP header called “DNT: 1” from your browser to every website you visit. This header signals your preference not to be tracked online. Each time your browser requests a page or resource, it includes the DNT header to tell the website you do not want tracking activities.

Here’s how Do Not Track works and what it asks websites to do:

Sends the HTTP header “DNT: 1” with every request from your browser.
Signals preference to stop tracking via cookies, fingerprinting, behavioral ads, third-party scripts.
Requests websites to stop tracking behaviors, which include storing tracking cookies on your device, using fingerprinting techniques to identify you, behavioral advertising, and running third-party tracking scripts.
These activities collect data about your browsing habits without explicit permission.

However, Do Not Track has a major limitation: it relies on websites voluntarily respecting your preference.

Depends on voluntary compliance; websites may ignore it.
Often disregarded by major platforms and ad networks. Many sites and advertising platforms ignore the DNT signal, continuing to track users regardless.
There is no enforcement or legal requirement to honor Do Not Track. This means the feature alone may not guarantee privacy.

Because of this, you should consider alternative or complementary tools to reduce tracking online.

Use in combination with privacy extensions, browsers, or VPNs for real protection.
These options include installing privacy-focused browser extensions like do not track extension add-ons, using privacy-oriented browsers, or connecting through VPNs that hide your IP address.

Related Privacy Tools and Frameworks

You’ll want to go beyond Do Not Track when managing your privacy. CookieYes is an example of a Consent Management Platform (CMP) designed to handle cookie consent requirements that DNT doesn’t cover. CMPs collect, store, and manage your consent to cookie use, helping websites follow data privacy laws.

Two important laws regarding cookie consent are the GDPR (General Data Protection Regulation) in Europe and California’s CCPA and CPRA. The GDPR requires sites to get active opt-in consent before tracking cookies are placed. CCPA and CPRA give users the right to opt out of the sale or sharing of personal information, including for advertising tracking.

Besides CookieYes, popular CMP providers include:

OneTrust
TrustArc
Usercentrics
Quantcast Choice

These solutions help sites comply with privacy rules while respecting your preferences.

Frameworks for Advertising and Analytics

The Interactive Advertising Bureau’s Transparency and Consent Framework (IAB TCF v2.2) is the standard many websites use to manage consent for personalized ads across multiple vendors. CMPs help websites integrate this framework easily.

Google Consent Mode is another tool that works alongside CMPs. It connects with Google tags and ad scripts, automatically adjusting how ads and analytics behave based on your consent choices.

Enhanced Browser Features

Browsers also offer enhanced privacy features that complement Do Not Track. For example:

Firefox’s Enhanced Tracking Protection blocks many trackers by default.
Google’s Privacy Sandbox initiative aims to reduce third-party tracking.
Brave browser provides built-in shields that stop ads and trackers immediately.

You can test your privacy compliance and consent setup with tools like Cookie Checker by CookieYes or the Google Consent Mode Checker. Legal compliance checkers for GDPR and CCPA help make sure websites meet requirements.

Why Do Not Track Might Not Be Enough

You should know that Do Not Track is voluntary. No law currently forces websites to honor it, so many ignore it completely. Sites and advertisers use many tools to keep tracking, regardless of your DNT setting. These methods are frankly egregious:

first-party and third-party cookies;
fingerprinting your device;
server-side tracking that doesn’t even rely on cookies.

Ad networks and analytics services often do not respect Do Not Track at all. This means simply enabling DNT doesn’t guarantee your browsing data stays private.

Network Masking Solutions

Stronger privacy control comes from using cookie consent management platforms (CMPs) that enforce your choices under privacy laws. Plus, adding privacy-enhancing browser extensions such as uBlock Origin or Privacy Badger blocks trackers on many sites. Using standalone tools like VPNs (for example, NordVPN or ExpressVPN) hides your IP and encrypts your traffic.

Another powerful addition is a service like Proxy-Seller, which offers reliable proxy servers, including residential, ISP, datacenter IPv4/IPv6, and mobile proxies. By routing your internet traffic through these proxies, you mask your real IP address and reduce direct tracking. This adds a technical layer of protection beyond browser settings like Do Not Track.

Proxy-Seller Capabilities:

Supports SOCKS5 and HTTP(S) proxies with high speeds up to 1 Gbps. This helps you safely bypass geo-restrictions and avoid some IP-based tracking.
Their extensive proxy network covers over 220 countries and supports multiple protocols, giving you flexibility and control.
They provide 24/7 support and comply with GDPR and CCPA, meeting the needs of privacy-conscious users seeking better anonymity and security than what Do Not Track alone can offer.

Summary: DNT's Failure and the Real Fix

In summary, here’s why Do Not Track might fall short and what you can do:

DNT compliance is voluntary; many ignore it.
Tracking continues using cookies, fingerprinting, server-side methods.
Ad networks and analytics often bypass DNT signals.
Use CMPs for enforceable consent and legal compliance.
Add privacy extensions like uBlock Origin, Privacy Badger.
Use VPNs (NordVPN, ExpressVPN) or Proxy-Seller proxies to mask IP and reduce tracking.
Proxy-Seller offers high-speed, multi-protocol proxies in 220+ countries with 24/7 support.
Emerging privacy laws push toward mandatory consent, impacting tracking practices.
Relying only on Do Not Track risks giving false confidence in privacy protection.

To Summarize

The “Do Not Track” standard is not legally binding, and websites are not obligated to comply with this request. Despite enabling “Do Not Track”, many websites and advertising networks may choose to disregard these requests and continue collecting user activity information.

By disabling the “Do Not Track” feature in popular browsers, you allow the tracking of information necessary for analytics and the collection of important data for further interaction with websites.

Internet safety is important. We all value our privacy and strive to remain anonymous online, especially when sharing sensitive information such as passwords and banking details. As a result, many of us rely on proxies, VPN services, and secure DNS servers, especially when using public Wi-Fi in places like coffee shops or shopping malls.

However, despite our best efforts, we can still encounter a DNS leak that compromises our privacy. Why does this happen, and what are the risks? How can we protect ourselves and maintain anonymity online? Let's delve into these important questions.

How Does a DNS Leak Work?

When you type a website address, your device asks a DNS server to translate that domain name into the website’s IP address. This process involves sending DNS queries from your device to DNS servers. Normally, when you use a VPN, all your internet traffic, including DNS queries, goes through an encrypted tunnel to the VPN’s private DNS servers. This keeps your requests hidden from your ISP and other outside parties.

A DNS leak happens when DNS queries bypass this secure tunnel and go directly to your ISP’s or other unknown DNS servers. This means your browsing activity is exposed even though you are connected to a VPN. To understand this better, imagine two flows: in a secure connection, DNS queries are encrypted and routed through the VPN’s private servers. During a DNS leak, DNS queries travel outside this encrypted path, exposing your internet requests.

DNS queries may follow a lifecycle that involves both recursive and iterative queries to resolve domain names step by step. Common DNS record types include A (IPv4 addresses), AAAA (IPv6 addresses), and CNAME (aliases), all crucial for turning domain names into IP addresses your browser can understand.

Modern DNS encryption protocols like DNS over HTTPS (DoH) and DNS over TLS (DoT) help prevent DNS leaks by encrypting these queries end-to-end. They add an extra layer of protection by making sure DNS traffic remains private beyond the VPN tunnel.

In summary, a DNS leak breaks the promise of VPN privacy by allowing DNS queries to be sent outside the VPN's secure channel. Running a DNS leak test or check helps you spot if leaks happen and keep your online activity safe.

What Causes DNS Leaks?

You’ll find many causes of DNS leaks, often linked to VPN or system settings errors. Here are the main reasons.

Misconfigured VPN Settings

If your VPN does not route DNS queries to its private DNS servers, leaks occur. Switching networks frequently can disrupt VPN routing, leading to leaks.

How to troubleshoot: Always select VPN providers that use private DNS servers to reduce risks. To check your VPN DNS setup, use commands like nslookup or dig and observe which DNS server answers.

Lack of IPv6 Support

Many VPNs only handle IPv4 traffic, letting IPv6 DNS queries slip through unprotected (read more about the difference between proxy and VPN).

How to troubleshoot: If you don’t need IPv6, disabling it on your device minimizes leaks. Follow these quick steps:

On Windows: Go to Network Settings > Adapter Options > Select your connection > Properties > Uncheck “Internet Protocol Version 6 (TCP/IPv6).” For a more detailed walkthrough, you can also check the full guide on proxy settings on Windows 10.
On macOS: Open Terminal and run networksetup -setv6off <networkservice> replacing <networkservice> with your active interface.
On Linux: Use terminal commands to disable IPv6 temporarily or edit system files for permanent disablement.
On routers: Access settings via web interface and disable IPv6 under network or advanced options.

Teredo Tunneling Protocol

Teredo is Microsoft’s IPv6-over-IPv4 tunneling system. It can bypass VPN tunnels unintentionally.

How to troubleshoot: Disable Teredo on Windows by opening Command Prompt as admin and running netsh interface teredo set state disabled.

Transparent DNS Proxies

Some ISPs intercept your DNS queries and force them through their servers. This may occur due to censorship, filtering, or security reasons.

How to troubleshoot: Detect transparent proxies using tools like DNSLeakTest or by monitoring traffic with Wireshark.

Windows Smart Multi-Homed Name Resolution (SMHNR)

SMHNR sends DNS queries to multiple DNS servers and uses the fastest response, often leaking to ISP DNS servers.

How to troubleshoot: Disable it using Group Policy Editor under Computer Configuration > Administrative Templates > Network > DNS Client or via registry edits.

Also, buggy or outdated VPN software, or OS-specific misconfigurations on Windows, macOS, Linux, iOS, or Android, can cause leaks. Use network diagnostic tools such as tcpdump, Wireshark, nslookup, or dig to audit your DNS traffic regularly.

What is the Danger of a DNS Leak

A DNS (Domain Name System) leak occurs when your device sends DNS requests through servers that differ from the ones you configured. This can happen when using a VPN or proxy, where the traffic bypasses the secure tunnel and goes through the regular ISP channel to the DNS servers assigned by the provider or operating system.

DNS: A Quick Explanation

For those unfamiliar with the topic, a brief explanation: DNS (Domain Name System) is used to convert human-readable domain names like google.com into machine-readable IP addresses such as 192.168.0.1 or text-numeric IPv6 addresses like 2018:0ab6:84a2:0000:0000:7a2b:0271:7435. This conversion allows network equipment to redirect traffic to the correct destination.

You can think of DNS as a telephone directory, but instead of numbers, it contains interpretations of domain names into IP addresses. Every time you enter a website address in your browser's address bar, your device accesses the DNS to find the corresponding IP address.

So Why Unencrypted DNS is a Danger

The issue with DNS (Domain Name System) requests is that they aren't encrypted, even if the website you're visiting uses HTTPS for encryption. This means that your browsing history can be seen by your internet service provider or hackers, especially when connecting to public Wi-Fi. What's more concerning is that your IP address and ports become visible to the website owners you visit, which can be exploited by scammers to intercept your data packets.

Privacy Exposure and Tracking

A DNS leak is a serious privacy risk. It exposes your DNS queries to third parties, including your ISP or hackers. This exposure lets attackers track your browsing habits and build detailed profiles of you.

Facilitating Direct Cyber Attacks

DNS leaks also facilitate attacks such as DNS spoofing and hijacking, which can redirect you to fake websites that spread malware or ransomware or phish for your information. These intercepted queries amplify the risk of social engineering attacks and malvertising.

Performance and Business Risks

Leaks can slow down your internet connection or cause access issues when domain resolution is tampered with. For businesses, DNS leaks aren’t just privacy issues but compliance risks. This can lead to violations of GDPR, HIPAA, or other data protection laws, resulting in fines or reputational damage. DNS leaks can serve as a gateway to costly data breaches.

Proxies and VPNs: The Anonymity Tools

To maintain anonymity online, people use VPNs (Virtual Private Networks) and proxy servers.

Proxy Server

A proxy server acts as an intermediary between your device and the target website. When you use a proxy, your device connects to the proxy server and sends all traffic, including DNS queries, through it instead of directly to the target site. This means that your online activities appear to be coming from the proxy server, keeping your information hidden from the target site. Proxies can also change your IP address. HTTPS and SOCKS5 proxies encrypt the traffic between you and the server, further protecting your data from being intercepted by your ISP or hackers.

Encrypted private proxies offer even higher traffic security. Elite private proxies can reduce latency (ping) by filtering out spam traffic and using caching.

VPN (Virtual Private Network)

A VPN (Virtual Private Network) offers an alternative method for anonymizing your online activity. It establishes a secure, encrypted connection over your existing internet connection. Your data is then routed through this secure tunnel to a remote server, which acts as a firewall. This means that your internet service provider (ISP) cannot see what information is being transmitted through the secure channel, nor can they see your DNS request history (as only one connection is made to the remote server). Importantly, complete anonymity is maintained as your DNS requests are sent to the VPN service's IP address instead of directly to DNS servers.

The Consequences of a Leak

However, it's important to note that using anonymization tools – proxies or VPNs – does not guarantee complete security. One possible issue that can compromise your security is a DNS leak, where your traffic bypasses the secure channel and goes directly, potentially exposing your online activity.

A DNS leak can lead to several issues:

Providers or attackers who access the DNS server can see your browsing history, even if you're using anonymizing tools.
Your unencrypted traffic, including sensitive data like bank card information, logins, and passwords, can be intercepted by hackers when you connect to public Wi-Fi hotspots.

How to Check For DNS Leaks On Your Device

Security frameworks such as NIST SP 800-53 and CIS Controls emphasize protecting DNS traffic as a key step in cybersecurity strategies.

Use an online testing detection service to perform two tests: first without the anonymization tool, and then with the proxy or VPN enabled. Compare the results. If they differ, it indicates that DNS requests are being redirected. For example, use the “DNS leak test” website.

Start by visiting the website and running a scan with the proxy or VPN turned off.\n
$\"1.png\"$
\n
Note the result:\n
$\"2.png\"$
\n
Next, enable the proxy, ensuring that the entire Windows OS is proxified so that traffic is directed through the desired IP.\n
$\"3en.png\"$
\n
Return to the DNS leak test.com website and perform a second check:\n
$\"4.png\"$
\n

Compare the results. If the IP addresses differ, it indicates that there is no leak.

How to Avoid DNS Leaks

DNS leaks are most commonly experienced by users of desktop computers and laptops running the Windows operating system. However, this issue can affect anyone, regardless of their device type or operating system.

Common causes of DNS leaks and how to resolve them:

Incorrect Proxy Server Settings

DNS leaks often occur due to misconfigurations in the proxy or the DNS server used by the proxy. Some proxy clients may use their own DNS settings, bypassing the proxy settings and leading to data leakage. Another common issue is when the proxy doesn't support DNS protocols like UDP, allowing DNS queries to bypass the proxy and be sent directly.

How to fix it? Use protocols supported by proxies and enable appropriate DNS filters to reduce the risk of leaks. If you discover a leak, try manually configuring your network connection or router and installing a reliable DNS server. You can change or set a permanent DNS server address in the router settings under the DHCP section (primary and secondary DNS fields). Additionally, read this useful tutorial if the proxy is detected.

You can also specify DNS in the network connection settings. Here's how to do it on Windows:

Open “Settings” and navigate to the “Network and Internet” menu.
In the “Status” tab, select the “Adapter settings settings” menu.\n
$\"6en.png\"$
\n
Choose the network adapter or virtual connection, right-click on it, and select “Properties”.\n
$\"7en.png\"$
\n
In the list of components, find the line Internet Protocol TCP/IP v4, click on it, and then click on the “Properties” button. In the settings, set the DNS address.\n
$\"8en.png\"$
\n
$\"9en.png\"$
\n

The process for setting up DNS is similar for iOS, Android, Linux, and Mac. You'll need to go to the settings of the network device and edit the DHCP or TCP/IP parameters.

Using Unreliable DNS Servers

Some Internet providers route all user requests through their DNS servers, but often these servers are not secure. Attackers can exploit vulnerabilities and intercept user requests, redirecting them to fake phishing sites. This issue also arises with third-party public DNS services.

To address this problem, use secure DNS servers that support DNSSEC technology, such as OpenDNS, Google Public DNS, or Cloudflare. If you use a VPN, specify the static DNS servers provided by the VPN operator in the Wi-Fi router settings.

Viruses or Use of Unsafe Applications

Viruses and malicious applications can alter the network settings of your device and redirect DNS requests to fake servers. This exposes your online browsing history. The more significant risk is that these fake servers can redirect you to phishing sites that steal your logins, passwords, bank card details, and payment system data. Similar DNS issues can occur on Android and iOS devices.

To prevent this problem, regularly scan your system for viruses and keep your operating system updated. Periodically check for DNS leaks and which servers your computer or smartphone is accessing.

Using a Transparent Proxy

A transparent DNS Proxy involves installing a proxy at the local network level and redirecting all traffic through the proxy server without additional configuration of the network card or installation of a client on user devices. However, using a transparent proxy often leads to DNS leaks. Providers sometimes use this technology to collect information about the websites their customers visit.

When using a transparent proxy, DNS requests are redirected directly through the provider's servers, even if static DNS servers are specified separately, a separate proxy connection is established, or DNS filters are used.

The simplest solution to this problem is to purchase elite proxies with traffic encryption. If a DNS leak occurs due to network settings, change the configuration of your network equipment:

Prohibit connections through port 53 in the firewall rules, which is used with Transparent DNS Proxy technology, and redirect to another port, such as 5353;
Set a static DNS, such as Google's public servers: primary - 8.8.8.8, and secondary - 8.8.4.4.

The Fraud Scoring System is an anti-fraud tool used in the IT industry to evaluate the likelihood of fraudulent or deceptive behavior in various online activities, including financial transactions, e-commerce, and online payments. This system is essential in areas where fraud protection and customer reliability are crucial.

The term “FraudScore” is also commonly used in relation to IP addresses. Many online services claim to assess the “FraudScore” of an IP address, purporting to check for potential fraudulent activities associated with it. This is particularly relevant for users interested in the credibility of an IP address, such as after purchasing a proxy. However, these online checkers are not related to the Fraud Scoring System and generally do not provide accurate or relevant information.

In the following sections, we will explore the concept of an IP address's Fraud Score, discuss its reliability, and guide you on how to evaluate the trustworthiness of your own or a purchased IP address.

Video: What is Fraud Score and Its Impact?

The Meaning and Role of FraudScore on The Internet

The significance of fraudster identification systems is paramount in ensuring online security. However, the value of assessing the fraud risk of IP addresses is debatable and tends to be minimal. This skepticism is due to several factors:

The lack of transparency in how FraudScore checkers analyze and collect IP data, raising concerns about compliance with privacy regulations like GDPR and CCPA.
Inconsistencies in fraud scores across different checkers.
The possibility of false negatives (safe assessment for suspicious IPs) and false positives (high fraud scores for “clean” IPs).

Given these shortcomings, the reliability of such checkers in detecting IP address fraud is questionable. Therefore, relying on public resources for evaluating your own or a purchased IP address is not recommended.

A more effective approach involves assessing other indicators of an IP address, such as its presence on blacklists/spam lists and its anonymity level.

Various IP checkers offer comprehensive analysis, providing information about:

blacklist status, indicating if the IP is linked to spam or malware;
geographic location and details about the registering entity;
connection type, including whether the IP is static or dynamic, and the nature of the network connection (e.g., broadband, mobile).

Ultimately, the purpose of these IP checkers is to enhance online security and safeguard users against potential threats.

How to Check FraudScore IP Addresses

Exploring operational methods for IP checking, we focus on specialized online services. As previously discussed, relying solely on Fraud Score is not reliable. Instead, let's consider other important indicators obtained during IP checks.

To begin, here's how to gather general information about your IP:

Choose an IP checking service, like IPQualityScore, that can verify if the IP is listed on blacklists or deemed unreliable.\n
$\"1en.png\"$
\n
Navigate to the “IP Reputation Check” section on the service’s website.\n
$\"2en.png\"$
\n
Enter the IP address you wish to check. The result will display various details about the IP, such as its location, provider, and whether it's listed on spam lists. Interestingly, while these checks do reveal a Fraud Score and an overall risk level, they often lack specifics on how these figures are calculated or what constitutes a high risk of fraud.\n
$\"3$
\n

For a more comprehensive evaluation, it’s advisable to cross-reference IPs using separate blacklist checkers. This approach ensures a more thorough assessment of the IP's reliability.

Checking an IP Address for Presence in Blacklists

Let's take the DNS Checker service as an example, which analyzes data from over 50 databases. Here's how to use it:

Visit the service's main page, navigate to the “Tools” section, and under “IP-Tools”, select “IP Blacklist Checker”.\n
$\"4en.jpg\"$
\n
Enter the IP address you wish to check. Alternatively, you can click the “Your Own IP” button to have the service automatically detect and check your IP.\n
$\"5en.jpg\"$
\n
Click the “Check in Blacklists” button.\n
$\"6en.jpg\"$
\n
The service will quickly display a list of blacklist databases, indicating whether your IP is listed in each.\n
$\"7en.png\"$
\n

It's important to note that an IP’s presence in one database doesn’t necessarily imply unreliability. However, if the IP appears on multiple blacklists, it's generally advised not to use it.

IP Address Anonymity Check

Checking your IP for anonymity is also crucial, as it reveals how other sites perceive your online identity and whether sensitive user information is visible. Since an IP address can contain data that's not only useful for web service analytics but also vulnerable to attackers, it's important to understand what your IP reveals.

Here's how to conduct an anonymity check using the 2ip checker:

Visit the website and navigate to the “Tests” section.\n
$\"8en.jpg\"$
\n
From the available options, select the “Anonymity check” tool.\n
$\"9en.jpg\"$
\n
The initial page will display basic information about your IP and location as seen by other resources. For a more in-depth analysis, click the “Check” button.\n
$\"10en.png\"$
\n
The service will provide a list of parameters used to analyze your IP, along with a percentage indicating the likelihood of using a VPN or proxy. A lower percentage suggests a higher level of anonymity.\n
$\"11en.png\"$
\n

This check helps assess how “clean” and safe your IP is for use (more about “clean proxies”). However, keep in mind that results from online IP checkers may vary and might not be entirely comprehensive, depending on the service used.

Enhancement of Fraud Scoring with AI and Machine Learning

Traditional rules-based FraudScore systems have apparent limitations. They rely on fixed rules that can be inflexible and easy for fraudsters to bypass. These systems often produce high rates of false positives, flagging legitimate activities as fraudulent. They also miss important context and patterns that don’t fit preset criteria.

AI and machine learning (ML) overcome these limits by learning from data and adapting over time. Instead of static rules, AI/ML models identify complex and new fraud patterns instantly. They use supervised learning from labeled fraud cases, unsupervised learning for anomaly detection, and reinforcement learning to improve decision-making continuously.

Key benefits of AI/ML in FraudScore systems include:

Detecting emerging fraud tactics immediately through pattern recognition.
Utilizing network intelligence by analyzing aggregated global data with graph databases like Neo4j, clustering algorithms to group suspicious activities, and privacy-preserving federated learning frameworks such as TensorFlow Federated and PySyft.
Adapting dynamically as fraud tactics evolve by continuous model training using platforms like MLFlow and Kubeflow.
Reducing false positives and alert fatigue by combining anomaly detection with confidence scoring to prioritize genuine threats.
Preserving privacy by sharing metadata across organizations without exposing personal data, thanks to federated learning.
Integrating seamlessly with existing systems via APIs and SDKs, enabling real-time FraudScore check automation in payment gateways and CRM platforms.

You’ll also benefit from “whitebox” systems that provide explainable decisions through explainable AI (XAI) tools like LIME and SHAP. These solutions make AI’s FraudScore decisions transparent, helping you trust and refine the system.

In contrast to rigid rules, AI/ML models learn continuously and generate features automatically from data, making fraud detection smarter and more agile. Harnessing network intelligence is essential – it enriches FraudScore analytics and helps stop synthetic fraud attacks by spotting links between entities that rules miss.

Best Practices for Implementing FraudScore Systems

Implementing a successful FraudScore solution requires a comprehensive, practical strategy. You’ll want to:

Collect data from multiple sources, including user behavior, device info, external threat intelligence, and transaction metadata. This diversity strengthens your analytics.
Continuously train and retrain AI/ML models with fresh fraud data using active learning and automated labeling to keep detection sharp.
Combine transparent, customizable rules with AI enhancements for a hybrid system. This balance allows human oversight while benefiting from machine speed and learning.
Use real-time scoring to enable fast, automated responses integrated into payment processing and risk management workflows.
Foster cross-team collaboration among risk, data science, IT, and customer service using agile methodologies and collaborative tools like Jira and Confluence.
Monitor performance constantly and adjust scoring thresholds with dashboards such as Power BI or Tableau while setting up proactive alerts.

Tools and approaches to support these best practices include:

Flexible rules engines like IBM Operational Decision Manager or Drools to maintain human control.
MLOps frameworks such as TFX or Seldon Core that automate feedback loops and model refinement efficiently.

Here’s a practical checklist to get started:

Set up diverse data pipelines to gather comprehensive FraudScore IP and user data.
Design hybrid models blending rules and AI for adaptive FraudScore analytics.
Deploy real-time FraudScore checker APIs within your payment and CRM systems.
Establish cross-functional teams for ongoing FraudScore pricing evaluation and model tuning.

By following these best practices, you’ll build a robust FraudScore system that evolves with threats and efficiently safeguards your business.

Common Challenges and Limitations of Fraud Scoring

While FraudScore systems grow smarter, challenges remain. One major issue is inconsistent scoring thresholds across companies. This inconsistency causes interoperability problems when sharing fraud data or insights. Static, outdated models quickly lose effectiveness against rapidly changing fraud methods.

Inaccurate FraudScore results may lead to false positives that erode customer trust or false negatives that result in losses. The quality and completeness of your data play a huge role – missing or noisy data weakens model performance. Finally, regulatory demands and ethical concerns require transparency and fairness in automated decisions.

How to Manage These Challenges Effectively

\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n

Challenge or Limitation	How to Fix
Inconsistent scoring thresholds	Update models regularly and monitor performance continuously using tools like DataRobot or Databricks.
Static, outdated models
Inaccurate FraudScore results	Ensure accurate, integrated data from various sources (CRM systems, device telemetry, external threat intelligence feeds such as IBM X-Force and VirusTotal).
Poor data quality/completeness
Regulatory demands & ethical concerns	Implement bias detection and mitigation to maintain fairness and avoid discriminatory effects in scoring.

Managing these factors protects your FraudScore system’s reliability and reputation while complying with regulations.

Some use cases of a proxy or VPN involve the need to be able to identify the mere usage of these tools. At times, you may be curious about whether your proxy usage is detectable, and if it is, how to hide it.

Various methods exist to detect proxy usage, most of which are concealed within the computer and browser.

The specific type of proxy used holds significance, in this case, our focus is on anonymous proxies. All types can be considered as such if they refrain from transmitting any information in the header during a request (refer to the description below).

If the proxy is detected, check the following settings:

Also keep in mind that the proxy type matters: residential proxies can look more like real-user traffic and may reduce automated ‘proxy/VPN detected’ triggers on some sites.

Browser HTTP headers.

Analysis of headers sent by the browser. If the header is passed, it means the proxy is not anonymous, and there is a risk that your actual IP address may be disclosed.

Headers that can expose your real IP:

HTTP_VIA
HTTP_X_FORWARDED_FOR
HTTP_PROXY_CONNECTION
X_FORWARDED_FOR
FORWARDED_FOR
FORWARDED
HTTP_FORWARDED_FOR_IP
HTTP_FORWARDED_FOR
FORWARDED_FOR_IP
HTTP_X_FORWARDED
HTTP_FORWARDED
HTTP_CLIENT_IP, VIA, X_FORWARDED
CLIENT_IP

Flash Leak, Java Leak, and WebRTC Leak. Plugins like Adobe Flash, Java, and WebRTC can unintentionally reveal your real IP address. It is advisable to disable these plugins.
DNS Leak.

DNS queries can potentially leak the IP address of the DNS server closest to you and bypass your Proxy/VPN connection.

How to safeguard against DNS leaks:

Force the required DNS servers in the connection settings.
Install specialized proxy programs that intercept and redirect DNS requests through your Proxy/VPN/TOR.
Disable third-party plugins such as Flash, Java, WebRTC, and Silverlight.
Use utilities to hide IP and encrypt traffic with built-in protection against DNS Leak.

Fingerprints. Browser and system fingerprint analysis.

Proxies are commonly used on Linux and BSD systems but less frequently on Windows. Users often overlook changing their User-Agent, which contains information about the operating system used in the browser. If you’re trying to match a mobile user profile, pairing a mobile User-Agent with a mobile proxy server can make the overall fingerprint more consistent.

ETag. Compare cached Entity Tag identifiers.

ETag can serve as a user identifier. If your IP address changes but the ETag remains stored in the browser cache, the resource can potentially identify you. It is crucial to completely clear the browser cache after modifying or using a proxy/VPN connection.

MTU/MSS/p0f check. Passive TCP/IP stack listening methods.

When using this method, the size of the Maximum Transmission Unit (MTU) value is compared. Encapsulation occurs when using a proxy, and with OpenVPN, the system retains the MTU size but can modify the Maximum Segment Size (MSS) within the packet. In some environments, testing with an IPv6 proxy can also help you compare whether detection patterns differ between IPv4 and IPv6 routes.

To prevent information disclosure through MTU/MSS, manual editing of these settings for the network adapter is necessary.

Blacklists. Proxies can be checked against large Realtime Blackhole Lists (RBLs) for potential inclusion in blacklists. To reduce blacklist-related flags, consider rotating cleaner pools or switching to ISP proxies, which are often less likely to be mass-listed than datacenter ranges.
Differences between the local time and IP time zone.

If detections persist even after tuning headers and fingerprints, consider changing your proxy provider to access a cleaner IP pool and better routing stability.

Nowadays, dedicated proxy servers can be an integral part of your work on the network. They can be used for normal web surfing as well as for more specific tasks such as social media management, web scraping, gambling, gaming, accessing geo-restricted content, etc.

But quite often even experienced users get confused about formats, not everyone understands what are datacenter proxies and what are residential isp proxies, as well as which proxies they should choose. Very often it is not so easy, and even experienced users cannot always decide whether it is better to buy a legit residential proxy or a datacenter one will be enough. Let us tell you right away that static isp proxy and data center proxy have their benefits, and each of these formats has its disadvantages.

In this article we will help you to understand what kind of proxy you should choose comparing datacenter vs residential proxies.

Video: Identifying proxy IP type: Residential or DC?

What are Datacenter proxies

Datacenter proxies are proxy servers located in data centers that act as intermediaries between users and websites, allowing users to access content with geographic restrictions and bypass some restrictions. DC proxies have gained recognition for its remarkable performance, high speed, and their proxy services cost. They are primarily used for anonymous web browsing, accessing geo-restricted content, betting, online gaming, etc.

Please note that there are different formats of proxies from the data center. The main separation is between IPv4 and IPv6 proxies. In order not to go into details of the technical characteristics we will identify the key difference between them, which will most likely help you - with datacenter IPv4 proxy you can open almost any website on the Internet, while with datacenter IPv6 proxy you can work only with a few major ones, such as Facebook, YouTube, Google, etc., which makes the price of IPv6 proxies lower than the IPv4 proxies.

There are also different types of proxies, namely:

Dedicated datacenter proxies are IP addresses specifically assigned for a set period or dedicated to a particular domain. These proxies offer exceptional speed and are ideal for businesses engaged in activities like social media, SEO, and many other purposes.
Public datacenter proxies are freely available proxies that serve basic needs, such as changing locations to access geo-restricted websites. However, they typically have inferior performance and security compared to shared and private datacenter proxies.
Shared datacenter proxies, as the name suggests, are shared among multiple users who utilize them simultaneously. These proxies are suitable for small businesses with limited budgets or specific needs.

Data center proxies have the largest market share for the reason that these proxies are hosted by large companies with the most advanced equipment, which allows you to get a stable proxy uptime and a nice speed for a fairly low price. This option is also good for those who need proxies in large quantities.

What are Residential ISP proxies

A static residential ISP proxy is a type of proxy that is purchased or leased from Internet service providers (ISPs). What they have in common with dc proxy is that they are also hosted in datacenters, but they are recognized by the target resources as real users. Therefore, for some purposes, they are considered proxies with a higher anonymity level because they are a more secure proxy type.

Static ISP proxy is a very good option for some of the target tasks, namely:

Web Scraping: The combination of good speed and a high level of anonymity help you produce more efficient research and attract more customers from certain locations. Therefore, ISP is almost an ideal option among web scraping proxies. For example, the appearance of captchas on the proxy format ISP will be much less frequent than on proxies from data centers, as ISP proxies have a more natural behavior and can match the normal user traffic. At 40-50 requests per minute on the proxy from the datacenter the appearance of captchas will be inevitable, while on the ISP proxy the probability of appearance of captchas will be much lower, especially if these requests correspond to the natural user behavior
Sneaker websites: Most often, sneaker sites are quite well protected, which is why many users have problems selecting proxies for this purpose. The way out can be ISP residential proxy because by connecting through this type of proxy for sites your IP address looks like that of a real user, which increases the probability of successful work with such target resources as Nike, Adidas, Footlocker and others.
Social Media Monitoring: Engaging in activities like social media monitoring, similar to SEO monitoring, can potentially trigger suspicion and lead to being blocked or banned from the platform. For instance, if you manage multiple accounts using the same IP address, it can raise red flags. To overcome this challenge and avoid being blocked, ISP proxies can be highly beneficial. These proxies deceive social network algorithms by presenting different IP addresses, ensuring that you can carry out your activities without the risk of being blocked.

Datacenter vs Residential ISP proxies

In order to consolidate all the above information when comparing datacenter vs residential proxies, let us summarize the technical features:

ISP proxies, despite being hosted in data centers, are provided by internet service providers (ISPs). These proxies are known for their authenticity and offer a wide range of use cases with remarkably fast performance. Therefore, a residential isp proxy would be a good option for many local tasks.
Datacenter proxies are IP addresses that are not tied to a specific home-based ISP. They are proxy servers located in data centers and serve as intermediaries between users and websites. Datacenter proxies are commonly used for various purposes such as online anonymity, and accessing geo-blocked content.

Pros of Datacenter proxy

Geographic flexibility: With datacenter proxies, you can access geo-restricted content or services by routing your traffic through IP addresses from different locations.
Cost-effective: Compared to other types of proxies, dc proxy tend to be more affordable, making them an attractive option for many users.
High uptime: Datacenter proxies typically offer high uptime and reliability, ensuring consistent access to websites and online services.
Good connection speed: You can get excellent proxy speed at the expense of the very advanced hardware from the datacenter providers.
Large IP pool: Datacenter proxies often have a vast pool of IP addresses and reducing the risk of IP blocking or detection.

Cons of Datacenter servers

However, static datacenter proxies also have disadvantages that should not be missed:

Lack of residential association: Datacenter proxies are not associated with residential ISPs, which can make them easier to detect by websites or services implementing anti-proxy measures.
Not suitable for certain activities: Certain activities that require genuine residential IPs, such as online account creation or accessing region-restricted services with strict verification processes, may not be feasible with static datacenter proxies.

Pros of residential ISP proxy

Genuine residential IP addresses: ISP residential proxies use IP addresses assigned by Internet Service Providers (ISPs) to residential users, providing a higher level of authenticity due to the real provider detection.
Suitable for web scraping and automation: Residential ISP proxies are often preferred for web scraping or automation tasks as they provide a more reliable and sustainable solution with lower risk of detection.
Lower risk of detection: Residential proxies are less likely to be detected as proxies since they closely resemble regular residential connections and have a fairly high trust level of ip, reducing the chances of being blocked or flagged using legit residential proxy.
High connection speeds: ISP proxies, through they are located in data centers, provide users with high-speed performance, which makes them a great option if you are looking for a proxy with high anonymity and at the same time good proxy speed.

Cons of Residential ISP servers

But let's not forget that this type of proxy also has disadvantages:

Less geographic variety: It is likely to be problematic to find some small locations for this type of proxy, here they lose out to proxies from the datacenter.
Smaller IP pool: For datacenter proxies, there will likely be a much wider variety of different hosts and subnets available, while for resident ISP proxies there may only be a few per location.

Which proxy type to choose

Finally, you may still have the question, which datacenter or residential proxy to choose?

For Web-scraping, sneaker websites or any other services with good proxy protection, you'd better use ISP residential proxy. If your main goal is access to geo-restricted content, anonymity or web browsing - a proxy from data center will be enough for you. If your task is more specific, you should also choose a proxy more carefully.

When choosing datacenter vs residential proxies, keep this factor in mind as the key one - what purpose will you use them for? Because for each goal and for each site recommendations will be different. For some tasks, it also makes sense to buy mobile proxy In order not to make a mistake in choosing a proxy, you should always consult either the support of your proxy provider, or other users who also use proxies for this purpose.

Also, do not forget that it is always best to choose private proxies because it increases the probability of successful work with proxies for practically any task, and also choose good proxy providers. Remember that good proxies are always an investment, and the better the proxies you buy, the more successful you will be in handling the task you need the proxy for.

When purchasing or using a proxy, the objective remains consistent - to alter your location or perform various essential tasks while operating from a specific geographic position. It is important to remember that this must be achieved while maintaining a significant degree of anonymity.

Let's delve into what lies beneath the concept of “IP anonymity on the network”.

IP anonymity - how “clean” is the outgoing address in relation to the requested resource. It reflects the level of “transparency” in the information provided by the device when a request is made.

Video: What affects proxy/IP anonymity

What affects high IP/proxy anonymity scores

Flash has been deactivated in the browser.
WebRTC has been deactivated.
The device's language corresponds to the proxy geo.
Differences in the system, local time, and time zone are present.
A clean user-agent is used/generated in the browser.
The IP address/proxy is not listed in any blacklists.
The DoNotTrack function has not been enabled.

Ordinary users mistakenly include in this list such a concept as DNS of IP address, which are not considered when constructing an IP or proxy anonymity profile. It is merely a parameter of affiliation.

Most services and websites we regularly access, including those used in our work routine, store data regarding the IP address from which requests are made. For example, gambling websites, cryptocurrency exchanges, marketplaces, and so on. This “knowledge” of our address is irrelevant as long as the terms of use of the service/website are not violated. But in case of misuse of services - sanctions can be applied. The easiest way is to analyze the IP address of the profile, the main criteria are:

Whether a proxy was used during interactions with the service.
Whether the IP address has been previously associated with another user.
The number of profiles within one subnet and their level of interconnectedness.
The actions performed under the IP address.

Recommendations for using proxies:

Considering the listed IP anonymity criteria mentioned at the beginning of the article, it is crucial to select a reliable provider and determine the type of proxies to be used. Primarily, private proxies are recommended, and the choice of proxy type depends on both the budget and the use case.

Several factors that affect the proxy server anonymity level:

Proxy server type: Certain proxy types, like SOCKS, offer a higher degree of anonymity compared to others, such as HTTP(s).
Level of user identification: The extent to which user information is transmitted through the proxy server impacts its anonymity level. Some proxies may reveal the user's IP address, while others keep it hidden.
Proxy server quality: Factors like speed and reliability of the proxy server can influence its level of anonymity.
Proxy server location: Proxy servers located in countries with stricter internet policies and robust data protection laws tend to provide a heightened level of anonymity.
Number of users sharing the same proxy server: When multiple users share the same proxy server, the anonymity of each user diminishes.

To ensure a high level of anonymity, it is generally recommended to select proxy servers that provide a minimal level of user identification and are located in countries with more free internet policies.

A browser fingerprint, or digital fingerprint, is a unique browser identifier that allows websites to track information about a user's browser and device. When a browser sends a request to a website, it exchanges data that makes up the digital fingerprint with the web server, allowing the target site to gather information about the user. This guide explains how to check browser Fingerprint and discusses different ways of changing it.

Video: What are Fingerprints, How To Check And Change Them with Anti-Detect Browsers And Extensions

Anatomy of a Digital Fingerprint

The fingerprint directly affects a user's anonymity online, as it includes information such as:

User-Agent – details about the browser version, operating system of the device, and other characteristics of the user's computer.
Cookies files – store information about a user's interactions with websites.
Supercookies – collect information even in private browsing mode, often without the user's knowledge, and are stored in various repositories, making them more difficult to delete and different from regular cookies.
Do Not Track – a setting that allows users to express their preference not to be tracked by websites.
Additional information such as system fonts, browser history, active plugins and their versions, and time zone.

It is also worth mentioning Canvas Fingerprinting, a technology similar in function to the standard digital fingerprint but with some differences. This method uses the HTML5 Canvas element to create an invisible image in the user's browser, which is then converted into a unique digital code. Due to differences in how various browsers and devices render images, the code becomes unique to each user. This technology is often used in conjunction with standard fingerprinting to enhance the accuracy of user identification.

How Browser Fingerprinting Works

Browser Fingerprint works by collecting many different “signals” from your browser and device to create a unique profile. These signals include attributes like your browser type, screen resolution, installed fonts, and hardware details. By combining these diverse pieces of information, the systems build a high-entropy identifier. This identifier is unique enough to distinguish you even if your device is similar to others.

To keep this ID stable, fingerprinting tools weigh each signal by how unique and consistent it is over time. For example, your browser version changes less often than your IP address, so it holds more weight. Minor changes in your setup won't break the fingerprint; it adapts to maintain your persistent ID.

Data Collection and Analysis Flow

Scripts running in the background gather this data without slowing down or interrupting your experience. They collect info asynchronously, using fallbacks when certain browser APIs are not available.

A typical data collection flow looks like this:

The script queries browser APIs for attributes.
Collects canvas or WebGL hashes.
Polls device memory and network info.
Sends these signals to a server.

There, statistical entropy calculations determine how unique your fingerprint is compared to others.

Advanced systems rely on machine learning and server-side analysis to improve reliability. They analyze patterns using algorithms like Random Forest or Neural Networks to increase identifier stability and detect anomalies.

Anti-fraud heuristics also apply. Systems detect suspicious behavior by clustering similar fingerprints, spotting outliers, and correlating user actions with their fingerprints. This helps prevent spoofing and enhances security.

Common frameworks and tools used include JavaScript fingerprinting libraries and machine learning models. These work together to collect, analyze, and verify signals in near real-time, making sure the fingerprint is accurate and hard to fake.

How and Where Fingerprinting is Used

Initially, fingerprint technology was developed to prevent fraudulent activities online. For example, digital fingerprints were actively used by banking institutions to quickly and effectively identify suspicious activity on their sites. Over time, the functionality of this technology has expanded significantly, and it is now used in virtually all areas of Internet activity.

Applications of Digital Fingerprinting

Many companies and web resources collect information about their visitors for further analysis of behavioral factors, such as what users pay attention to most often and which pages they visit the most. This information helps to later adjust the content on the resource and make personalized advertising more effective. For instance, if a user is surfing the internet on an outdated smartphone, various services, having this information, can offer personalized advertising for new-generation smartphones.

Another important role of fingerprinting is providing users with a website optimized for a specific device. Based on the digital fingerprint, the server understands from which device the site is being accessed and opens the appropriate version.

Fingerprinting as an Online Identifier

Thus, a fingerprint, along with the user's IP address, is their main identifier online, and to achieve the highest level of connection anonymization, it is necessary to change these parameters.

Using different digital fingerprints is beneficial, for example, when handling multiple accounts. By setting up separate fingerprints for different accounts, one can avoid unwanted blocks and associations between profiles, as the server will not be able to track that the accounts are being used by the same person. Next, we will look more closely at the options available to users for changing their digital fingerprint.

Information Gathered in Browser Fingerprinting

You’ll find that browser fingerprint test tools collect a wide range of attributes. These include basic details that create a basic profile:

browser type and version:
operating system:
screen resolution, color depth:
installed fonts, plugins:
timezone, language:
whether you use an ad blocker.

But fingerprinting goes deeper with technical details, such as:

HTTP headers like accept headers and connection types.
Canvas fingerprinting outputs (hashes of rendered images or text).
WebGL vendor and renderer strings revealing GPU differences.
Battery status from the Battery API.
Device memory size and number of CPU cores.
Touch support capabilities.
Audio context fingerprint parameters measuring subtle hardware differences.

For example, font enumeration works by using JavaScript to measure text width when rendered in different fonts. This lets fingerprinting scripts identify which fonts you have installed – a unique device trait. Plugin detection no longer relies on the old plugin enumerations but now uses MIME type checks and feature detection.

To gather these data points, fingerprinting scripts tap into multiple browser APIs, including:

navigator API for system/device info;
screen API for display parameters;
device Memory API for RAM size;
network Information API for connection details;
performance API for timing measurements.

Popular demo tools like FingerprintJS, AmIUnique, and Panopticlick allow you to check browser fingerprint attributes and see their entropy, giving you a practical view of what’s being collected.

How to Check Your Device’s Fingerprint

There are several ways to check your fingerprint, but not all of them are equally informative. Specific parameters of the digital fingerprint, such as the User-agent, can be determined using the browser's developer tools. To do this, press F12, navigate to the “Console” section, and enter the command – console.log(navigator.userAgent).

$\"0.png\"$

However, a more convenient way to check the digital fingerprint of a device is to use specialized online checkers such as:

Pixelscan;
Ipqualityscore;
Scamalytics;
Uniquemachine;
Whatleaks;
Privacy.

To check your fingerprint just open the specialized website, and the information about the device will most often be displayed on the homepage. Let's provide examples of what this might look like.

$\"2en.png\"$

When changing the digital fingerprint later, online checkers can be used to verify whether the necessary parameters have changed and, if necessary, make further adjustments to the settings.

Different Ways of Changing Fingerprint

Changing the parameters of the digital fingerprint can significantly increase user anonymity online and also avoid blocks in the realm of multi-accounting. There are many ways to substitute a Fingerprint, each with its degree of effectiveness. Let's examine them in more detail:

using anonymous mode in the browser, which prevents the collection of cookies, history, and other information that makes up the Fingerprint;
disabling Flash and JavaScript plugins in your browser can limit access to information such as system fonts, screen resolution, and time zone;
configuring anonymization tools, such as proxy servers, can change the user's geolocation and IP address, which also helps partially modify the browser's Fingerprint;
installing specialized browser extensions that allow partial changes to the Fingerprint or block its detection;
using anti-detect browsers, which allow for manual configuration of most of the digital fingerprint data or random selection.

Using just a proxy server, as well as working through anonymous mode in the browser, does not fully change the digital fingerprint, which makes their separate application ineffective. In turn, disabling plugins can affect the display of content on websites. Therefore, let's consider the two most effective methods: using specialized extensions and anti-detect browsers for changing the Fingerprint in conjunction with configuring a proxy server.

How to Change Fingerprint Using a Browser Extension

Plugins for managing digital fingerprints can be found in browser extension stores. These plugins allow blocking the transmission of certain fingerprint parameters to the target server to ensure a higher level of online anonymity. Let's see how this works using the “Privacy Tweaks” extension, available for Google Chrome and Mozilla Firefox.

$\"12.png\"$

On the main page of the extension in the “Tweaks” tab, there is a large number of switches that allow you to:

block websites from accessing data about your device;
prohibit the collection of information for further use in targeted advertising;
prevent WebRTC leaks;
change the time zone;
configure a proxy server to change the IP address;
block ads in the browser.

$\"13.png\"$

The “Settings” tab allows you to manually configure specific parameters, such as time zone, geolocation, proxy server, and the ability to add certain sites to the exceptions when working with the extension.

$\"14.png\"$

It is recommended to use Privacy Tweaks in conjunction with a private proxy server to provide an additional level of connection anonymization.

How to Change Fingerprint Using an Anti-Detect Browser

The most reliable method for substituting the Fingerprint is using anonymous browsers, many of which come with built-in functionality for precise configuration of these data. Let’s take a closer look at how to change digital fingerprint settings using the anti-detect browser AdsPower, which offers a free version with sufficient functionality for such purposes.

Launch the browser and click on the “New Profile” button at the top of the panel.\n
$\"5en.png\"$
\n
Locate the “Proxy” section, select the protocol, and fill in all required fields.\n
$\"6en.png\"$
\n
On the right side of the “Overview” window, you can notice a column with the main digital data. By clicking the “New Fingerprint” button, you can generate a random Fingerprint.\n
$\"6.5en.png\"$
\n
If more precise settings are needed, click on “Advanced Settings” at the bottom of the profile creation page. This will allow you to customize nearly any indicator, starting from the time zone, fonts, and system language, ending with the MAC address.\n
$\"7en.png\"$
\n
Ensure all necessary data is changed and click “OK” to finish setting up.\n
$\"10en.png\"$
\n
The created profile will appear in the “Profiles” tab. To start working with the new settings, click the “Open” button.\n
$\"11en.png\"$
\n
In the new browser window, open any site to check the Fingerprint. Ensure the data has changed.

This completes the setup using the AdsPower browser. Most anti-detect browsers operate on a similar principle.

Major Browser Fingerprinting Techniques and Mitigation

Understanding the major browser fingerprinting techniques helps you protect your privacy.

Canvas fingerprinting uses HTML5 canvas to render images or text and analyze subtle GPU and driver differences.
WebGL fingerprinting works similarly but uses 3D graphics for even finer detail.
Media device fingerprinting catalogs connected cameras and microphones (with permission).
TLS fingerprinting inspects parameters during TLS handshakes to identify your software stack.
Font fingerprinting lists installed fonts.
Audio fingerprinting analyzes hardware and software variations by processing sound via the Web Audio API.

Additional techniques include:

Battery Status API fingerprinting, though less reliable now due to privacy restrictions.
Network and Connection API data like downlink speed and round-trip times.
Bluetooth and USB device enumeration where allowed.
Behavioral biometrics from typing patterns, mouse movements, and touch gestures.
Timezone and locale variations adding subtle uniqueness.

Common JavaScript libraries, such as those within FingerprintJS, include modules for these techniques. However, modern browsers increasingly block or limit fingerprinting APIs.

Mitigation Strategies

To counter browser fingerprinting, you can use anti-fingerprint browsers designed to minimize exposed data and standardize fingerprints. But IP and geographic info can still reveal you.

Here, Proxy-Seller’s proxy services come in. By masking your IP address and location, Proxy-Seller reduces fingerprint uniqueness tied to your network. It offers fast, private SOCKS5 and HTTPS proxies with geo-targeting, covering residential, ISP, datacenter, IPv4, IPv6, and mobile proxies. Their high bandwidth and flexible API integrate smoothly with scraping or data collection tools, helping you evade fingerprinting that depends on IP and location signals.

Using Proxy-Seller alongside anti-fingerprint browsing techniques strengthens your anonymity and makes it harder for trackers to reliably identify you. Keeping an eye on your browser fingerprint test results regularly will help you maintain better privacy against these evolving tracking methods.

In Conclusion

It should be noted that the best solution would be to use anti-detect browsers in combination with proxies, which allows for a complete alteration of the fingerprint. This option is suitable for work in the fields of website promotion, cryptocurrencies, and advertising. For simpler tasks, users can use special browser extensions.

In the modern world of the Internet, most users use proxy servers to ensure anonymity and protect personal data. Even though everyone knows about their role as intermediaries, many are wondering what mobile proxies are, and how they differ from ordinary ones.

Mobile proxies are IP addresses issued by mobile operators that have the same properties as server (regular) proxies with a distinctive service delivery technology. They are also called rotating or reverse, or even back-connect.

The fact is that the website's page security algorithms do not block such IP addresses and are more lenient towards them, because they understand that mass access using this technology is used by mobile operators to access the network for their customers. In simple words, bulk operations are not considered suspicious, unlike data-center or residential proxies.

Video: What are Mobile Proxies? A simple explanation

Mobile 4G/LTE proxy types

All mobile proxies are made into three types http, http(s), and Socks.

HTTP Mobile proxy

This is the most common type and is used for web browsers and programs that support TCP connections. It helps to bypass regional blocking and IP bans.

HTTP(S) Mobile proxy

This type works based on an SSL connection and is more secure than HTTP. It should be used if you often enter your usernames and passwords or payment card details.

SOCKS Mobile proxy

This type of proxy is considered the most secure and advanced today. It provides complete anonymity and does not transmit real digital fingerprints, guaranteeing complete anonymity and reliable protection of personal data. When using this type, the target server will not track that you are using a proxy. The main purpose is specialized software for multi-accounting with multi-threaded connections.

Why mobile proxies are needed

Mobile proxies are worth buying for the following purposes:

SEO specialists and Internet marketers choose this type for scraping purposes, collecting keywords and queries, collecting a semantic core, mass posting, comments, and reviews in case of using multi-accounting;
In case of traffic arbitrage, to advertisers for use in targeting and contextual advertising, farming accounts;
For boosting social media profiles, subscribers, and mass likes;
Monitoring profiles and websites of competitors;
Software developers;
Ordinary users to ensure security and complete anonymity while surfing the Internet.

Where to get rotating 4G/LTE mobile proxies

You can buy mobile proxies on our website, they have a high-speed connection (10 Mbps) and are not limited by the bandwidth. IP addresses are rotated within 5 minutes automatically or every 10 minutes upon request. Private mobile proxies from Proxy-Seller are provided for convenient periods (1-2 weeks, 1-3-6-9-12 months). It is also possible to select the purpose which is guaranteed operable.

Dynamic mobile proxies from Proxy-Seller are equally well suited for both web browsers and various kinds of software.

We offer to buy high-quality private proxies for Coinlist on the website proxy-seller.com, which will help you use the advantages of multi-accounting for the most efficient work on this platform.

What is Token Sale

Token Sale is a preliminary, limited sale of a new cryptocurrency on a specialized website to provide it to potential investors and raise capital for development before entering the main crypto exchanges. At this stage, for investors, this is a chance to make investments with minimal investment, where risks can turn into hundreds of percent profits. And for developers, a kind of real test of their startup and the opportunity to raise additional capital for promotion. One of the most popular platforms for token sales is Coinlist.

Coinlist review

Coinlist is an online service that simultaneously combines a crypto exchange and a platform for investing in a Token Sale. Among the advantages are:

Access to new tokens before anyone else;
High level of security;
Easy start;
A huge number of crypto projects;
Cross-platform.

Multi-accounting and proxies on the Coinlist exchange

Coinlist exchange has strict rules and advanced security algorithms. Despite this, users try to create and use a huge number of accounts at the same time. This is mainly due to the Token Sale. Developers sell a limited number of new tokens per user. Also, the opportunity to invest is limited, places on the list are often played out or provided randomly. The more profiles you have, the higher your chances of being shortlisted. Coinlist is trying to stop multi-accounting, and this is where private proxies for Coinlist come into play, which makes the simultaneous use of profiles from one device as anonymous and safe as possible, reducing the risks of blocking. In addition, proxies for Coinlist make it possible to switch from a manual method of obtaining new tokens to an automatic one (using specialized bots).

Coinlist proxies from Proxy-Seller have 1Gb/s communication channels, stable ping, and simultaneous support for HTTP(s) and Socks5 protocols. These parameters allow you to simultaneously use a huge number of profiles, bypassing competitors in a matter of moments, doing it as anonymously as possible and without the risk of getting a ban.

A proxy list is a list of proxy servers (IP addresses and ports) that have been tested for operability and have responded to connection requests that can be used to work on the Internet. They can be available in tables or formed into .txt, .xml or .xlsx files for easy import, export to various software and services.

Depending on which proxy checker was used, you can get information such as: IP-address, port, country / city, response speed, type, anonymity, last update. The proxy list itself includes an IP address, a port, and if an authentication procedure is required, then also a username and password. In the vast majority of cases, they are separated by a colon.

There are free proxy lists, available to everyone and paid, which are provided by one person or by prior arrangement after payment, and no one else can use them anymore.

What are proxy lists used for?

If you are engaged in multi-accounting, mass mailing, cheat voting, buying exclusive things using third-party software (for example, sneaker bots), other massive operations on the Internet for which you need a lot of unique IP addresses or geolocations, then proxy lists come into play. For example, https proxy lists are used in antidetect browsers, when you need to perform many live operations from one device using different profiles and not get banned. If the process is automated by third-party software, then socks5 proxy lists are used more often. Although there are many options on the network, proxy lists consist of all possible types (http, https, Socks4, Socks5). Summing up, we can say that proxy lists are needed for bulk operations from one device, where a lot of unique things are required.

Paid vs Free

You may ask why should I pay if there are free proxy lists? The answer is very simple, it all comes down to quality. The fact is that creating a proxy list requires some effort and expense, so free options are very rarely updated, their IP addresses are taken from different servers with different response times, and they can simply be dead (inoperable). Free proxy lists are simultaneously used by a large number of users, and through their fault they can be blocked on a particular resource. In addition, proxy server connection protocols may not always be suitable for your tasks in such lists. Also, the more concurrent connections, the lower the speed. Therefore, the use of free proxy lists is always full of risks, failures and nerves.

Paid proxy lists are provided exclusively to one person, and you independently decide how to dispose of them. Buying them, you can choose a specific type of connection protocol, and you are also provided with a separate server with a dedicated high-speed channel connection up to 1 Gbps. You do not have to additionally check them for operability, it is enough to load them into your software and use them for your own purposes.

The purpose of proxy lists

You can often hear why I need a proxy list if I only need a few proxy servers? First, buying proxy servers one at a time is expensive. Secondly, it is always better to have several proxies in reserve, website algorithms are constantly being improved and there is a chance that this or that IP address can be blocked, get banned. Thirdly, you can always resell your proxy list or part of it in order to get the money back. Can be shared with friends, used for other projects.

If you automate your work in social networks, online games, and do web-scraping, then proxy lists are simply necessary, they will help make the process continuous, fast and of high quality.

The best proxies can only be many private proxies or proxy lists. If anonymity and a high level of protection of personal data on the Internet play an important role for you, as well as multitasking is an integral part of your work, then proxy lists will become a reliable assistant and an integral part in the process of automating all actions.

Domain Name System (DNS) is a specially created Internet technology, the main task of which is to turn the name of a website into an IP address for users to access it through web browsers. DNS servers, by their very essence, resemble a phone book, where each name corresponds to the number to which the call is made. Only in this case does the name correspond to the IP address. Use DNS to speed up the connection to the target resource.

What is a DNS Server: Definition and Functionality

A DNS server is a specialized computer that holds a large database mapping domain names to IP addresses. This mapping lets you use easy-to-remember domain names like example.com instead of numeric IP addresses like 93.184.216.34. When you type a URL into your browser, the DNS server helps find the correct IP address so your device can connect to the website.

The process of finding an IP address is called DNS resolution. It involves different types of queries: recursive and iterative.

In recursive queries, your local DNS resolver asks other DNS servers on your behalf until it finds the answer.
In iterative queries, each server provides the best answer it can, and your resolver asks the next server.

The process starts with root servers, which direct queries to top-level domain (TLD) servers like .com or .org. TLD servers then point to authoritative name servers, which hold the exact IP address for the domain.

Here’s a typical DNS request in action:

You enter a URL in your browser.
Your device asks the recursive resolver for the IP address.
The resolver queries root servers, then TLD servers, then the authoritative server.
The authoritative server responds with the IP address.
The resolver returns the IP to your device.
Your browser connects to the website’s server using the IP.

Core Types of DNS Servers

There are several types of DNS servers involved:

Recursive resolver: Your local server that starts the DNS query chain.
Authoritative name server: Holds definitive DNS records for domains.
Root server: The highest-level server that points to TLD servers.
Forwarder: Helps route DNS requests to other DNS servers, often for caching or filtering.

DNS queries use UDP on port 53 for speed. If the response is too large or for specific tasks like zone transfers, the query falls back to TCP.

DNS servers use caching to store responses temporarily, reducing repeated queries and speeding up future lookups. Each DNS record has a Time-To-Live (TTL) value that tells the cache how long to keep the data before fetching fresh information. When TTL expires, the cache invalidates the record and asks authoritative servers again. Caching minimizes latency and reduces load on authoritative servers.

Understanding this process helps you troubleshoot issues like how to fix DNS server not responding errors and learn how to change DNS server settings for better performance or security.

How DNS Works

The moment you enter the name of the site in the address bar, the web browser contacts the nearest DNS server to match the name you specified with the IP address and then connects to it. The problem is that not all DNS servers contain information about all names and their IPs.

If the name you specified is not in the database, then the request is redirected to another DNS server, which makes the connection time longer. DNS servers of such companies as Google (8.8.8.8.8 / 8.8.4.4) with huge databases that many users register instead of those provided by their provider help to fight this problem.

Types of DNS Records and Their Management

DNS records are key instructions stored on DNS servers. Each type has a specific role that keeps the internet running smoothly.

Here’s a practical list to help you understand common DNS record types, their purpose, and examples:

A record: Maps a domain to an IPv4 address (e.g., example.com → 93.184.216.34).
AAAA record: Maps a domain to an IPv6 address (e.g., example.com → 2606:2800:220:1:248:1893:25c8:1946).
CNAME record: Creates an alias from one domain to another (e.g., www.example.com → example.com).
PTR record: Used for reverse DNS lookup, mapping IP addresses back to hostnames.
NS record: Specifies the name servers responsible for a domain.
MX record: Lists mail exchange servers for handling email, with priority values.
SOA record: Start of Authority; contains primary zone control details like serial number, refresh, retry, and expiration times.
TXT record: Stores text data for verification and policies, such as SPF records for email validation and domain ownership proofs.
CAA record: Defines which certificate authorities can issue SSL certificates for the domain.
SRV record: Locates services by specifying ports and protocols (e.g., SIP, XMPP).

Historically, DNS zones were managed with BIND-style zone files and transferred between servers via AXFR or IXFR protocols. Today, most DNS management happens through web-based control panels like cPanel, Plesk, Cloudflare, or Amazon Route 53. These interfaces feature validation tools and syntax checkers to reduce errors.

You can also diagnose DNS record issues using external testing tools such as DNSViz or MXToolbox, making sure your settings work correctly. Automation tools like Terraform and Ansible help deploy and manage DNS records at scale, reducing manual errors.

Common human errors include

typos;
TTL misconfigurations;
improper use of CNAME records.

To prevent these, use tools with record locking, maintain audit trails, and set up change notification alerts. These practices help maintain a reliable and secure DNS setup.

How to Set Up DNS on a Router

Administrators of huge networks with a large number of switching users practice setting up DNS on the router. This solves the problem with the need to configure DNS on each device separately and significantly saves time. What the DNS setting looks like on popular routers, we will tell you in more detail later.

Router TP-LINK Archer A6

To start setting up DNS on this router, you need to find out the IP address of high-quality DNS servers and then follow these steps.

Open any web browser and write 192.168.0.1 or 192.168.1.1 in the address bar and click execute to go to the router settings.
To get access to the settings, you need to go through authorization by login and password. By default, they are, in most cases, 'admin' and 'admin'.
In the settings window you need to click on the \"Advanced\" tab and select \"Network\", and then the sub-item \"Internet\".\n
$\"1.png\"$
\n
On the right side of the window, you need to open additional settings. This can be done by clicking on the \"Advanced\" button.\n
$\"2.png\"$
\n

Security Threats to DNS Servers and Protective Measures

DNS servers face many security threats that can disrupt service or redirect users to malicious sites.

Here are the main DNS attack types you need to know:

Amplification Attack: Exploits open recursive resolvers to amplify traffic and flood targets with DDoS attacks through reflection.
Spoofing (Cache Poisoning): Injects false DNS data into caches, redirecting users to harmful IP addresses.
Flooding Attack: Overwhelms servers with excessive queries, causing disruptions.
Hijacking: Alters DNS settings at the ISP or device level to redirect traffic for phishing or censorship.

DNS primarily uses UDP, which is connectionless and easier to spoof compared to TCP used in zone transfers. This makes securing DNS servers essential.

Protective Measures for DNS

To protect your DNS server:

Harden your DNS software by disabling open recursion if not needed and apply rate limiting or Response Rate Limiting (RRL).
Keep DNS server software updated (BIND, Unbound, PowerDNS, Microsoft DNS) to patch known vulnerabilities.
Implement DNSSEC to authenticate DNS responses with digital signatures, preventing tampering.
Use DNS over HTTPS (DoH) or DNS over TLS (DoT) to encrypt DNS queries, improving privacy and blocking interception.
Deploy firewall rules, intrusion detection/prevention systems like Snort or Suricata, and DNS firewall solutions such as Cisco Umbrella or Infoblox.

ActiveX is a software platform. Based on it are built software components written in programming languages. ActiveX software can consist of one or more components for solving various tasks. Below we will tell you more about the settings of this platform, about what ActiveX is, and how to disable it.

How ActiveX Works

ActiveX is built on the Component Object Model (COM), a Microsoft technology that creates reusable software components. Each ActiveX control functions as a COM object.

Core Functionality

Each COM object exposes specific interfaces that other programs use to interact with it. These interfaces define methods and properties, enabling seamless communication between applications.

ActiveX manages an object’s lifecycle by controlling its creation, usage, and cleanup, ensuring efficient memory and resource management.

ActiveX controls often run scripts using languages like VBScript or JScript. These scripts allow controls to perform tasks beyond simple display, such as modifying files, reading or writing to the Windows registry, and interacting with other system resources. This deep access is powerful but also raises security concerns.

Packaging and Registration

Common ActiveX controls include:

multimedia players like the Windows Media Player control;
toolbars that enhance browser functionality;
document viewers;
PDF readers embedded in web pages.

These controls come packaged as .ocx files, which must be registered in Windows using system tools like regsvr32. This registration links the control to the operating system, allowing Internet Explorer and other compatible applications to find and run them.

Understanding the packaging and registration of ActiveX controls is critical. The registration process adds entries to the system registry, which helps the browser recognize and trust the control before execution. This process also affects how the control interacts with web content and the operating system, setting the stage for potential security risks if improperly managed.

Browser Compatibility

ActiveX is tightly linked to Internet Explorer. Other browsers such as Chrome, Firefox, and even modern versions of Edge do not natively support ActiveX controls.

Although some extensions or legacy modes try to enable this support, compatibility remains limited. For example, features like ActiveX for Chrome or ActiveX Chrome plugins often require third-party add-ons that mimic Internet Explorer’s environment.

Why Do I Need an ActiveX Framework?

What is ActiveX COM? This is a software platform whose controls act as building blocks for programs. With their help, you can create distributed applications that will work in the browser. The result is customizable software that allows you to collect data, view files, display animations, etc. ActiveX controls can only be officially processed by Explorer and Windows.

You should know how to disable the ActiveX Flash Player, as this software platform has a serious minus. Because of it, you can mistakenly install malware on your computer: viruses, spyware, etc. Below we will provide you with detailed instructions for activating and deactivating this framework on different browsers.

How to Configure ActiveX in Internet Explorer 11

To activate the elements of this framework in the browser, take 5 simple steps:

Launch Explorer 11.
Click on the \"Tools\" menu, and then go to \"Internet Options\".
Go to the \"Security\" category and click on \"Custom Level\".
Scroll to the \"ActiveX controls and plug-ins\" section.
Here you need to set the \"Enable\" value for two lines, which are indicated in the screenshot:\n
\n

In this case, filtering in the same settings section is better off. It may interfere with the proper loading of some applications.

How to Disable ActiveX in IE

Do you need to disable ActiveX in Internet Explorer?

Go the same way as in the instructions above.
Only at the end set the value to \"Disable\".

ActiveX Setup for Chrome

In a browser from Google Chrome, this problem can be solved with the help of additional software. Find the IE Tab extension in the Google online store and install it on your browser.

$\"\"$

ActiveX Setup for Firefox and Other Browsers

Unfortunately, ActiveX is not provided for Opera, Firefox, Safari, and other browsers.

Using Chrome? Get more benefits by connecting it with proxies. Learn how to set up a proxy server in the browser of Google.

What to Do When Locking Controls

If you see notifications in the browser that ActiveX controls are prohibited or blocked, then you need to set the resolution manually.

Follow the step-by-step instructions:

Open Internet Explorer.
Go to the \"Service\".
There, select the \"Internet Options\" option.
Next, go to the \"Security\" tab.
In it, click on the icon \"Trusted sites\".\n
\n
Next, click \"Custom Level...\".
In the security settings, enable the component as shown in the screenshot.\n
\n

Risks and Security Issues with ActiveX

ActiveX controls have been a frequent target of security vulnerabilities. These include buffer overflows, which occur when attackers feed the control data larger than it can handle, leading to crashes or arbitrary code execution. Remote code execution vulnerabilities allow attackers to run malicious code on your PC by exploiting flaws in the ActiveX control. Privilege escalation issues can grant attackers higher access levels than they should have, putting your system and data at serious risk.

Attack Vectors

Malicious websites or infected documents exploit these vulnerabilities, often through drive-by downloads and phishing scams. These attacks silently install or trigger unsafe ActiveX controls if security settings are lax.

Some ActiveX controls are marked “not safe for scripting,” meaning they should not be run automatically by scripts. However, attackers sometimes bypass security prompts using social engineering or exploiting browser weaknesses.

Security Best Practices

To keep your system secure, disabling or carefully managing ActiveX controls reduces the attack surface. Microsoft has issued numerous security advisories on these topics, including MS06-013 and MS07-029. Regular cumulative security updates patch known ActiveX vulnerabilities, so keeping your system updated is essential.

Best practices for ActiveX security include:

Configuring kill bits to disable specific vulnerable controls.
Using code signing certificates to verify the authenticity of ActiveX controls before running them.
Employing Internet Explorer Enhanced Security Configuration (ESC) to reduce risks when browsing unknown sites.

Disabling ActiveX Using Group Policy

You can manage and disable ActiveX controls centrally using the Group Policy Editor (gpedit.msc), available on Windows Pro and Enterprise editions. This tool lets you apply consistent security settings across multiple computers in your organization.

Group Policy Steps

To disable or control ActiveX, follow these steps in Group Policy Editor:

Open gpedit.msc via the Run dialog.
Navigate to Administrative Templates $\\to$ Windows Components $\\to$ Internet Explorer $\\to$ Security Features $\\to$ Add-on Management.
Here, you’ll find settings such as:\n
1. \"Run ActiveX controls and plug-ins\" for different security zones (Local intranet, Trusted sites, Internet, and Restricted sites). You can enable or disable ActiveX on these zones separately.
2. \"ActiveX kill bits\" policies, which disable known vulnerable controls by blocking them from running.
3. Blocking unsigned ActiveX controls to prevent untrusted code execution.
\n

Security Zones and Enforcement

Each zone represents a different trust level for websites, impacting whether ActiveX controls can run. For example, controls may be allowed on Trusted sites but blocked on Internet or Restricted sites zones, limiting risks.

Organizations use Group Policy to enforce ActiveX settings for multiple reasons:

enhancing security on remote workstations;
meeting compliance requirements;
reducing user errors and helpdesk support related to ActiveX problems

For larger environments, administrators may deploy these policies using tools like the Policy Management Console (PMC) or System Center Configuration Manager (SCCM), providing scalable and centralized control.

Layered Protection with Proxy-Seller

To further improve security and maintain internet access when ActiveX is disabled or limited, consider using Proxy-Seller services.

Proxy-Seller offers reliable, high-speed SOCKS5 and HTTP(S) proxies with geo-targeting and IP rotation. This helps businesses maintain privacy, avoid IP bans, and control web traffic when using legacy ActiveX applications requiring internet connectivity.

If you continue to use Web Real-Time Communication technology, other Internet users will be able to track your personal data, in particular, your IP address. If there is no need to use this network protocol, it is better to disable WebRTC. Below we will describe in detail how to disable WebRTC in 5 popular browsers: Chrome, Opera, Firefox, Safari and Yandex.Browser (for CIS).

Video: How to Disable the WebRTC Feature in Popular Browsers

Why Disable WebRTC?

WebRTC can leak your real IP address to websites and trackers, even if you use a VPN. This issue is called the WebRTC leak phenomenon.

Consequences of WebRTC leaks:

It hurts your privacy because the leak exposes your ISP and geographic location. When your IP leaks, your VPN’s protection is useless. Your true IP becomes visible, revealing who you really are online.
These leaks can let hackers, advertisers, or governments track you more easily. WebRTC leaks combined with browser fingerprinting techniques make it simple to deanonymize you. Attackers use this info in targeted attacks or surveillance.
In real life, WebRTC leaks have exposed whistleblowers, activists, and journalists by revealing their location and identity. Because of this, it’s crucial to disable WebRTC or control it carefully for better privacy.
Besides leaks, WebRTC has vulnerabilities that attackers can exploit to gain access to your system or data. Disabling WebRTC reduces these risks too.

Benefits of Disabling WebRTC

The greatest troubles Web Real Time Communication will deliver to those users who care about their anonymity and security when working on the Internet. Yes, this technology is beneficial in terms of the convenience of sending audio and video streams and transferring data from the browser directly to mobile devices. But at the same time, WebRTC reveals the user's real IP address, which casts doubt on personal privacy on the network.

It will be doubly unpleasant for those who use paid proxy servers. Without disabling WebRTC in the browser, the user's real IP address will be revealed even when using third-party tools to hide personal data.

How to Disable WebRTC in Google Chrome

Follow the instructions:

Open the Google Chrome browser.
In the upper right corner, find the browser menu – three vertical dots. Press it.
Move the cursor over the More Tools submenu.
Select the Extensions option.\n
$\"\"$
\nAfter opening the list with installed extensions, click on the main menu of this section - three horizontally located strips, which are located in the upper left corner.
Click on the Open Chrome Web Store button.
In the Search the store field, enter the name of the plugin, WebRTC Control, to quickly find the software you need.
Click first on the first highlighted extension, and then on the Install button.
Confirm your desire to install the plugin by clicking on the corresponding button.
After that, the automatic installation of the extension will start. It activates on its own, so you don't need to do anything else.\n
$\"\"$
\n

Adjust plugin enable / disable by clicking on its icon in the extensions panel. If it's colored, it works. When gray - disabled.

How to Disable WebRTC in Opera

To deactivate this technology in your browser, follow the instructions below.

6 steps to disable WebRTC in Opera:

Launch your browser.
Google Addons store for Opera and follow the appropriate link.\n
$\"\"$
\nIn the add-on search engine, find the WebRTC Control program.
Click the green Add to Opera button to install the software to disable WebRTC.
The plugin will automatically launch, blocking WebRTC on your computer.
To check the plug-in activity, click on the Extensions icon, which is made in the form of a cube.\n
$\"\"$
\n

If the extension logo is displayed in color, then the software is working. Its colorless display will indicate that the plugin is disabled.

How to Disable WebRTC in Mozilla Firefox

To disable WebRTC technology in Firefox, follow the instructions:

Open your browser.
Enter the phrase about:config in the address bar.
Press Enter.\n
$\"\"$
\n
Confirm your intention to go to the browser settings editor by clicking the blue \"Accept risk and continue\" button.
Enter the value media.peerconnection.enabled in the search bar that appears.
Click on the icon on the right side to switch options.
Check for the appearance of the inscription False instead of True.\n
$\"\"$
\n

How to Disable WebRTC in Safari

To disable WebRTC technology in this browser, follow the instructions below:

Open Safari and click on the Safari menu item.
Go to Settings.\n
$\"\"$
\n
Go to the Advanced tab and put a check mark next to the item Show the Develop menu in the menu bar.
After that, a new section Develop will appear, click on it.
Move the cursor over the Experimental Features option.\n
$\"\"$
\n
Uncheck the Remove Legacy WebRTC API line.

Done. You have disabled this option in the Safari browser.

How to Disable WebRTC in Yandex.Browser

To solve this problem, you need to take a few simple steps:

Start Yandex Browser.
Search through a search engine for an online store of extensions for the Opera or Google Chrome browser - their products are both suitable for Yandex.Browser.
Enter the name of the software you need WebRTC control for into the plugin store search engine.
Click the button to install the extension.
Confirm the installation of the extension if a confirmation window appears.

The plugin will automatically start working when it is installed on your browser. If you need to disable it in the future, just click on its icon, which is located on the plugins panel.

Alternatives to Disabling WebRTC Completely

You don’t always have to disable WebRTC fully to improve privacy. Sometimes, limiting the IP exposure is enough while still keeping WebRTC’s useful features. To do this:

Configure your browser to expose only your VPN’s IP address in WebRTC requests.\n
- For example, in Chrome or Edge, set the WebRTC IP Handling Policy by entering chrome://flags.
- Choose “Default public interface only” or “Disable non-proxied UDP” to block local IP leaks but keep external IPs usable.
\n
Separate browsing tasks using containers or profiles.\n
- Use one browser profile with WebRTC enabled for trusted sites and another with WebRTC disabled for sensitive browsing.
\n

New browser security updates and experimental patches aim to reduce WebRTC leaks without disabling the feature entirely. Keep an eye on these developments, as they may offer better balance soon.

Partial mitigation approaches keep WebRTC functionality but may still expose some IP info. Full disablement removes all leaks but can break WebRTC-dependent web apps like video calls. Choose based on your privacy needs and which features you rely on.

Now you know why to disable WebRTC, how to protect yourself alongside it, and the alternatives if you can’t disable it fully. This practical approach helps keep your online identity safe and your browsing secure.

Additional Privacy Tips to Disable WebRTC Leaks

You’ll get better privacy if you complement disabling WebRTC with these practical steps:

Use VPNs with built-in WebRTC leak protection. Look for VPNs that handle both DNS and WebRTC leaks well. Here are some trusted options:

ExpressVPN
NordVPN
Surfshark
CyberGhost

Test your setup regularly: Use online tools to check if your IP is leaking via WebRTC.

browserleaks.com/webrtc
ipleak.net
whoer.net/webrtc

Choose a privacy-focused browser with WebRTC protections out-of-the-box.

Brave Browser: It disables non-proxied UDP connections by default, reducing leaks.
Tor Browser: It disables WebRTC entirely to block leaks completely.

Add privacy-focused browser extensions cautiously. Some help disable WebRTC, but may slow your browser or cause conflicts.

uBlock Origin (enable WebRTC blocking filters)
Privacy Badger (offers partial protection)
WebRTC Control extension (full disablement toggle)

Follow these quick tips too:

Disable unused plugins and add-ons.
Avoid granting unnecessary permissions to websites.
Keep your browser and extensions updated.

Finally, keep testing after every browser or VPN update to ensure your WebRTC protections still work.

For serious privacy protection, consider Proxy-Seller’s fast and reliable proxy servers. They mask your real IP even if WebRTC leaks happen.
