A SOCKS proxy is usually located between a local network and the Internet channel. SOCKS proxy servers have a few decided advantages over other types of proxies:

  • SOCKS uses low-level protocols (TCP, UDP) to transfer data, so it does not depend on HTTP or FTP, which are high-level protocols. A local software can make a SOCKS server act as a client-side server, so it enables the application to accept external connections, though a real IP address is not available;
  • application of SOCKS 5 technology enables to work via a proxy server for software that cannot do this initially.

Differences between SOCKS 4 and SOCKS 5 protocols:

  • SOCKS 5 can operate in networks without a local DNS. SOCKS 4 cannot do this;
  • SOCKS 5 transfers data via TCP and UDP, which enables not to use some protocols;
  • SOCKS 5 can perform authentication of a server and client;
  • one of SOCKS 5 basic features is its capability to process network addresses by IPv6. But there are some limitations, e.g., SOCKS has no data filtering mechanism. So, a proxy server built on SOCKS technology cannot see which type of data it transfers. Besides, a SOCKS proxy cannot be configured as a local server to be used as a web server, because there is no opened port for external connections.

You can enjoy advantages of the SOCKS-based high-rate connection by cooperating with proxy service. Hear you can work with over four thousand reliable and quick SOCKS proxy servers located at nearly all civilized countries and regions all over the world. And all of these is for an affordable price!
