Technical Summary

This document specifies an extension to the IPv6 multicast addressing
architecture to be used in the context of IPv4-IPv6 interconnection.
In particular, this document defines an address format for IPv4-
embedded IPv6 multicast addresses. This address format can be used
for IPv4-IPv6 translation or encapsulation schemes.

This document updates [RFC4291].

This specification can be used in conjunction with other extensions
such as building unicast prefix-based multicast IPv6 address
[RFC3306] or embedding the rendezvous point [RFC3956].

This document is a companion document to [RFC6052] which focuses
exclusively on IPv4-embedded IPv6 unicast addresses.

Working Group Summary

This draft has received solid support within the working group and no
major controversies were noted.

Document Quality

This document has received a number of comments from reviewers and the
authors addressed each of these comments. There exists at least one
implementation of this mechanism.


Lenny Giuliano is the Document Shepherd. Ron Bonica is the
Responsible Area Director.


Authors of this document request to reserve:
o ff3x:0:8000/33 SSM block to embed an IPv4 multicast address in the
last 32 bits.
o ffxx:8000/17 ASM block to embed an IPv4 multicast address in the
last 32 bits.
