Abstract:

   On networks providing IPv4-IPv6 translation (RFC7915), hosts and
   other endpoints might need to know the IPv6 prefix(es) used for
   translation (the NAT64 prefix).  While "Discovery of the IPv6 Prefix
   Used for IPv6 Address Synthesis" (RFC7050) defines a DNS64-based
   prefix discovery mechanism, more robust methods have been developed
   since then.  This document provides guidelines for NAT64 prefix
   discovery, recommending more deterministic alternatives like
   obtaining the NAT64 prefix from Router Advertisement option (RFC8781)
   over RFC7050 when available.
