[AusNOG] Internal use MAC addresses

[Paul Wilkins]

Alternatively, set B2 in the MAC's MSB to 1.This defines a locally
administered address.

That said, if you buy a NIC that's branded "ethernet", the burnt in address
will have been allocated by IANA to the manufacturer and will be unique. If
it's not unique, it's not ethernet.
