Ummm.  I assume a typo here, but the equivalent of a /31 in IPv4 world
is a */127*, not a /126...

Seconded.  EUI-64 sucks big time (using MAC addresses and such is a nice
idea, but why on earth can't they map 48 bits to 64 in a somewhat more
straightforward way than "distribute them over all the 64bits"?)
