There's also a new MBONED working group document you can expect to see
advance soon; it allows organizations to allocate their own multicast
addresses based on their IPv4 address allocations.
Dave Thaler of Microsoft wrote this draft. For the text, see
For example, Argonne owns the 22.214.171.124/16 address space; under this new
scheme Argonne would be therefore able to allocate addresses from
126.96.36.199/24. A hypothetical organization with 192.168.5.0/24 would be
able to choose how to use the group 188.8.131.52/32.
