Abstract

   This specification defines an extension to the multicast addressing
   architecture of the IP Version 6 protocol.  The extension presented
   in this document allows for unicast-prefix-based allocation of
   multicast addresses.  By delegating multicast addresses at the same
   time as unicast prefixes, network operators will be able to identify
   their multicast addresses without needing to run an inter-domain
   allocation protocol.
