Abstract

   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. [RFC 2365]).

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.
