Technical Summary

The specification for how a client discovers its local network's
NAT64 prefix [RFC7050] defines the special name 'ipv4only.arpa' for
this purpose, but in its Domain Name Reservation Considerations
section that specification indicates that the name actually has no
particularly special properties would require special handling, and
does not request IANA to record the name in the Special-Use Domain
Names registry.

Consequently, despite the well articulated special purpose of the
name, 'ipv4only.arpa' was not recorded in the Special-Use Domain
Names registry as a name with special properties.

This document describes the special treatment required, formally
declares the special properties of the name, and adds similar
declarations for the corresponding reverse mapping names.
