For those familiar with using SOCKS proxies, you might want to know what makes SOCKS4 different from SOCKS5. In a nutshell, version 5 of the protocol is more advanced. Here is a list of features that only apply to ver. 5:

- Authentication

- Support for UDP Proxy

- DNS requests can be sent through the proxy

Which version you use depends on the configuration of the server you're connecting to. It will either support 4, 5 or both. SOCKS4a is an extension that fixes a common name resolution problem.
