Oh, and, of course ::1 (v6 loopback), duh.

There also may need to be something done with the IPv4-embeddable-in-v6 range in the future:

The general range is allowable, but some subsets would clearly be bad, OTOH, most usage scenarios would have the "bad" ranges to an external V6->V4 tunnel, but it might still be a good idea to have 64:ff9b::{forbidden V4 addresses}

But until user systems start using this well known prefix, its not necessary.
