Discovering NAT64 IPv6 Prefixes Using the Port Control Protocol
Overview
RFC 7225, “Discovering NAT64 IPv6 Prefixes Using the Port Control Protocol”, is a Proposed Standard document published in May 2014 by M. Boucadair. The canonical text is published by the RFC Editor.
Abstract
This document defines a new Port Control Protocol (PCP) option to learn the IPv6 prefix(es) used by a PCP-controlled NAT64 device to build IPv4-converted IPv6 addresses. This option is needed for successful communications when IPv4 addresses are used in referrals.
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
