Free Proxy

A proxy is an intermediate server located between a user’s device and the target network server. It acts as a relay station between the two, responsible for forwarding the user’s network requests, receiving responses from the server, and then returning those responses to the user. Simply put, a proxy is like a middleman that allows users to access internet resources indirectly through it.

Based on functions and anonymity, proxies can be divided into various types: HTTP/HTTPS proxies, SOCKS proxies (such as SOCKS4 and SOCKS5), transparent proxies, anonymous proxies, and high-anonymity proxies.

Its functions include hiding the real IP address, bypassing network restrictions, caching and accelerating access, filtering content, and enhancing security.

It refers to whether the target server can identify your real IP and traces of proxy usage: a transparent proxy exposes the real IP; an anonymous proxy hides the IP but reveals the proxy identity; a high-anonymity proxy completely hides both.

It is recommended to replace them. Using the same proxy IP for a long time may be marked or blocked by target websites, especially for free proxies. Regular replacement can improve access stability.
