This describes an experimental policy for use of the class D address space using 233/8 as the experimental statically assigned subset of the class D address space. This new experimental allocation is in addition to those described on [IANA] (e.g. [RFC2365]).

1. Problem Statement
Multicast addresses have traditionally been allocated by a dynamic
mechanism such as SDR [SAP]. However, many current multicast
deployment models are not amenable to dynamic allocation. For
example, many content aggregators require group addresses which are
fixed on a time scale which is not amenable to allocation by a
mechanism such as described in [SAP]. Perhaps more seriously, since
there isn't general consensus by providers, content aggregators, or
application writers as to the allocation mechanism, the Internet is
left without a coherent multicast address allocation scheme.
The MALLOC working group is looking at a specific strategy for global
multicast address allocation [MADCAP, MASC]. This experiment will
proceed in parallel. MADCAP may be employed within AS's, if so
This document proposes an experimental method of statically
allocating multicast addresses with global scope. This experiment
will last for a period of one year, but may be extended as described
in section 6.
2. Address Space
For purposes of the experiment described here, the IANA has allocated
233/8. The remaining 24 bits will be administered in a manner similar
to that described in RFC 1797:
0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1
