On networks providing IPv4-IPv6 translation (RFC 7915), hosts and
other endpoints need to know the IPv6 prefix(es) used for translation
(the NAT64 prefix (RFC 6052)). This document provides guidelines for
NAT64 prefix discovery, specifically recommending obtaining the NAT64
prefix from the Router Advertisement option (RFC 8781) when
available.
This document is a product of the IPv6 Operations Working Group of the IETF.
