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 RFC 4291, IPv6 multicast addresses which are only different
in scope represent different groups. Nodes must join each group individually.
