IETF RFC 6146
Stateful NAT64: Network Address and Protocol Translation from IPv6 Clients to IPv4 Servers
|Publication Date:||1 April 2011|
This document describes stateful NAT64 translation, which allows IPv6-only clients to contact IPv4 servers using unicast UDP, TCP, or ICMP. One or more public IPv4 addresses assigned to a NAT64 translator are shared among several IPv6-only clients. When stateful NAT64 is used in conjunction with DNS64, no changes are usually required in the IPv6 client or the IPv4 server.
