RFC 3138             Extended Assignments in 233/8             June 2001


2. Overview

   http://www.iana.org/assignments/multicast-addresses defines a
   mechanism for assignment of multicast addresses that are generally
   for use in network control applications.  It is envisioned that those
   addresses assigned from the EGLOP space (233.252.0.0 -
   233.255.255.255) will be used by applications that cannot use
   Administratively Scoped Addressing [RFC 2365], GLOP Addressing
   [RFC 2770], or Source Specific Multicast (Source Specific Multicast,
   or SSM, is an extension of IP Multicast in which traffic is forwarded
   to receivers from only those multicast sources for which the
   receivers have explicitly expressed interest, and is primarily
   targeted at one-to-many (broadcast) applications).

3. Assignment Criteria

   Globally scoped IPv4 multicast addresses in the EGLOP space are
   assigned by a Regional Registry (RIR).  An applicant MUST, as per
   [IANA], show that the request cannot be satisfied using
   Administratively Scoped addressing [RFC 2365], GLOP addressing
   [RFC 2770], or SSM.  The fine-grained assignment policy is left to the
   assigning RIR.

4. Security Considerations

   The assignment scheme described in this document does not effect the
   security properties of the the single source or any source multicast
   service models.

5. Acknowledgments
