RFC 7050: Discovery of the IPv6 Prefix Used for IPv6 Address Synthesis

Still current, but amended. Parts of this document are changed or extended by RFC 8880. Read both.

In plain English — editorial summary, not part of the RFC

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.
