Is there a way on linux, based on MAC address, to get the IP of
the unit?
You accumulate a table of mac<->ip assocations, but only after
communicating with something. arp -a will show the current entries
(which expire fairly quickly). You might ping everything in the
network range, then look for the mac in the arp list.
to ping every address, check out broadcast pings here

(or google other how-to's)
then do the
arp -a
but keep in mind not everything responds to broadcast pings.
