Title : A64: DNS Resource Record for IPv4-mapped IPv6 Address

In the context of IPv4-IPv6 interconnection (or interworking),
several solutions have been proposed within IETF. Some of these
solutions require the definition of a new IPv4-mapped IPv6 address
[I-D.ietf-behave-address-format] which is used to represent an IPv4-
only host in an IPv6 realms and the definition of a new mechanism
called DNS64 for synthesizing a AAAA record, representing an IPv4-
mapped IPv6 address in the DNS system, from the A record representing
the IPv4 address of the IPv4-only host [I-D.ietf-behave-dns64]. This
IPv4-mapped IPv6 address, when managed by a translator, is to be
considered as "fake" address in a DNS system since it is not
necessarily assigned to any host's interface qualified by the
associated name. This document defines a new DNS record type and
query type to identify IPv4-mapped IPv6 address
[I-D.ietf-behave-address-format] from native IPv6 ones. The new
record type and query type aim at helping the requesting party to
enforce its policies and avoid crossing NAT64 boxes when possible.
Native addresses are to be preferred.
