How to check the validity of a proxy server

There are several ways to check the validity of proxy servers. Various software, scripts, and online checkers can test proxies. Programs have extensive functionality but require installation on a device and understanding their specifics. Scripts allow checking a large number of proxy servers, but using them requires specialized knowledge. The simplest and fastest way to check a proxy for free is through proxy checkers. They not only allow you to test the connection but also provide additional information about IP addresses.

Checking a proxy server can identify invalid IP addresses, helping to avoid problems such as:

  1. User IP address detection, which can lead to the leakage of confidential information;
  2. Internet providers or web resources tracking user activity;
  3. Slow connection speeds and issues accessing websites and applications;
  4. Wasting time and resources when working with invalid proxy servers;
  5. IP address bans and access restrictions by websites.

Thus, regular validation of proxy servers helps users secure their data, enhance internet connection performance, and access needed websites. Testing proxy servers with an online checker allows users to fully utilize the potential of proxies and select the most suitable servers for specific tasks.

What is a proxy checker

A proxy checker is a tool for checking that provides information about the functionality of proxy servers. The checker can determine whether the proxy server responds to requests and can also specify its IP address, level of anonymity, country, speed, and protocol type.

Proxy checker is useful for:

  • Quick and convenient validation of IP addresses, which is particularly important when using proxies for bypassing blocks or protecting data confidentiality.
  • Determining parameters such as anonymity, location, and protocol, which are relevant when choosing a proxy server needed for individual projects.
  • Sorting a proxy list by various categories for ease of use, for example, by speed, anonymity, country, or type.

A proxy checker can send requests to remote servers through a proxy and analyze request headers to determine if the user's original IP addresses are hidden. This is crucial for ensuring user anonymity and optimizing proxy performance. Checking the type of proxy server - HTTP(S), SOCKS, and its versions helps set up the connection correctly.

The advantage of a proxy checker is the ability to quickly test a proxy list online without the need for installing third-party software. Based on the test results, the user will receive comprehensive information on each proxy, with the ability to set sorting parameters by functionality, country, or protocol, allowing for quick filtering of valid proxies.

Using the checker, it is possible to test server, mobile, and residential proxies individually or as a list. The data obtained is an important indicator for securing internet connections and maintaining user privacy online.

How to use the proxy checker

The online proxy checker on our website is based on powerful, modern equipment, which allows it to process a large number of requests and display the testing results within a few seconds. A significant advantage of this checker is the ability to test the availability of search engines from different regions: USA - Bing, Europe - Google, Asia - Baidu. This provides highly accurate information about the server's functionality and response time.

To check the validity of proxies, follow these step-by-step instructions:

  1. Navigate to the “Proxy Checker” tool webpage and enter the list of proxies in the required format:
    • IP:PORT - for checking public proxies;
    • IP:PORT:USERNAME:PASSWORD - for checking private proxies with authentication.

  2. You can import the proxy list from your device by clicking on “Import from .txt or .csv”.

  3. To the left of the input field, checkboxes for “HTTP/HTTPS”, “SOCKS 4/5”, and “Non-working” are automatically marked. If necessary, uncheck the box, and the checker will exclude the corresponding proxy servers from the display.

  4. After completing these steps, click the “Check proxy” button.

The proxy check using the “Proxy Checker” is completed. Users can analyze the information based on the data obtained and take measures to enhance their level of online privacy and network efficiency, especially when performing tasks related to bypassing blocks, anonymous surfing, or data collection.

In case non-working proxies are detected, users can purchase valid private proxies on our website using the “Buy working” button located on the tool page in the “Check result” field.
