Socks4 And Socks5 Proxy

Socks4 and Socks5 type of proxy servers are different from normal proxy servers, because they support different protocols, and not only the standard HTTP.

Socks4 and Socks5 proxy servers are usually used for applications that require data transfer over internet. You can use socks4 and Socks5 proxy servers on applications like IRC, MSN, ICQ, Ventrilo, TeamSpeak, Games and probably every other application that sends and recieves data over internet.

The difference between Socks4 and Socks5 is that Socks4, the older version, doesn't support authentication, UDP and requires a full support of DNS. While the newer version supports both, and can rely on the Socks5 proxy server to perform the DNS lookup.
