  "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.",
