Discovery of the IPv6 Prefix Used for IPv6 Address Synthesis

Metadata

Publisher: IETF
Doc Type: Standard
Pages: 22
Abstract: This document describes a method for detecting the presence of DNS64 and for learning the IPv6 prefix used for protocol translation on an access network. The method depends on the existence of a well-known IPv4-only fully qualified domain name "ipv4only.arpa.". The information learned enables nodes to perform local IPv6 address synthesis and to potentially avoid NAT64 on dual-stack and multi-interface deployments.
