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.
This document is a product of the Behavior Engineering for Hindrance Avoidance Working Group of the IETF.
This is now a Proposed Standard.
