Sorry to be using up so much bandwidth...
But: IPv6 used to be completely classless. Until RFC 3513 (well, it's
predecessor, really) came along:
For all unicast addresses, except those that start with binary value
000, Interface IDs are required to be 64 bits long
I have no idea why this is in there, it doesn't seem to serve any
purpose and most operators are happy to break this requirement if
they feel the need.
