More on this. Now that I'm at the office, I can scan a larger selection
of MAC addresses. Out of the 38 machines currently on the segment, the
lower twelve bits of each MAC addresses are unique (this excluding broadcast
and multicast MAC addresses).

For non-broadcast/multicast MAC addresses, take the last N bits.
