IPv6 Multicast Address Space Registry

Last Updated
2010-03-11
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 XML and plain text formats.

Variable Scope Multicast Addresses

Reference
[RFC3307]
Note
These permanently assigned multicast addresses are valid over all scope
ranges.  This is shown by an "X" in the scope field of the address that
means any legal scope value.

As defined in [RFC4291], IPv6 multicast addresses which are only different
in scope represent different groups.  Nodes must join each group individually.
