Appendix B: Internet Multicast Addresses

Certain Class D IP networks in the range of 224.0.0.0 through 239.255.255.255 are used for host extensions for IP multicasting as specified in the Request for Comments (RFC) 1112 standard created by the Internet Engineering Task Force (IETF). The well-known addresses are assigned and maintained by the Internet Address Number Authority (IANA). RFC 1112 specifies the extensions required of a host implementation of the Internet Protocol (IP) to support multicasting.

A lot of abbreviations and acronyms are used in this appendix. The most important, found in the well-known addresses, are listed here:

DHCP  Dynamic Host Configuration Protocol

DVMRP  Distance Vector Multicast Routing Protocol

OSPF  Open Shortest Path First

PIM  Protocol Independent Multicast

RIP  Routing Information Protocol

RP  Route processor

This appendix describes the multicast addresses, the purpose of each address, and the RFC or contact acronym.

Warning 

These addresses are subject to change. If you cannot find an address listed here that appears to be assigned, refer to the following location: www.iana.org/assignments/multicast-addresses.
