2016-09-27 Stig Venaas IPv6 multicast addresses are defined in "IP Version 6 Addressing Architecture" . 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 . IPv6 multicast addresses not listed below are reserved. IETF Review The definition of any Realm-Local scope for a particular network technology should be published in an RFC. For example, such a scope definition would be appropriate for publication in an 'IPv6-over-foo' RFC. Any RFCs that define a Realm-Local scope will be listed in this registry as an additional reference in the Realm-Local scope entry. Such RFCs are expected to make an explicit request to IANA for inclusion in this registry. 0 Reserved 1 Interface-Local scope 2 Link-Local scope 3 Realm-Local scope 4 Admin-Local scope 5 Site-Local scope 6-7 Unassigned 8 Organization-Local scope 9-D Unassigned E Global scope F Reserved Expert Review These permanently assigned multicast addresses are valid over a specified scope value.
