This document describes three types of extensions of SOCKS Version 5 protocol [RFC1928]. A new address type and a new command for Requests and Replies are introduced. These extensions supplement the insufficient generic functions of the SOCKSv5 protocol. These extensions enable a SOCKS server to be used as a translator for IPv4 and IPv6 mixed heteregenous communications with ease. In addition, they make each homogeneous IPv4 and IPv6 communication efficient.
