IPv6 Multicast Address Space Registry Last Updated 2013-04-10 Expert(s) Stig Venaas Note IPv6 multicast addresses are defined in "IP Version 6 Addressing Architecture" [RFC4291]. This defines fixed scope and variable scope multicast addresses. IPv6 multicast addresses are distinguished from unicast addresses by the value of the high-order octet of the addresses: a value of 0xFF (binary 11111111) identifies an address as a multicast address; any other value identifies an address as a unicast address. The rules for assigning new IPv6 multicast addresses are defined in [RFC3307]. IPv6 multicast addresses not listed below are reserved. This registry is also available in plain text. Registries included below * Node-Local Scope Multicast Addresses * Link-Local Scope Multicast Addresses * Site-Local Scope Multicast Addresses * Variable Scope Multicast Addresses * Source-Specific Multicast block Node-Local Scope Multicast Addresses Registration Procedure(s) Expert Review Reference [RFC4291][RFC3307] Note These permanently assigned multicast addresses are valid over a specified scope value.
