Sure, but in IPv4 there is no implicit tie from the hardware MAC address
to the IP address; you have to arp to see who has it.  Also, if you
change the physical hardware (get a new MAC address) you can still get
the same IP address assigned to you.  So the IPv4 address is *NOT* tied
to the Mac (hardware) address.

I believe that Robert is asking for similar functionality in NM's
support for v4.

Unfortunately I'm not at the IETF this week so I cannot go ask people
myself on Bob's behalf.
