The last 64 bits are derived from the MAC of the interface, which is quite a good idea (we probably won't see MAC exhausion because it's only two-level, and it's supposedly guaranteed unique). The stupidity lies eleswhere. (Seriously. Just how fucking stupid do you have to be to replace a protocol whose addresses are too short, with one whose addresses are too short.)
