You don't need RARP except for a diskless boot. RARP says, "Here I am
(with MAC address ...); what is my IP address?"
To find the IP address of a MAC interface *which*your*machine*has*seen*,
use `/usr/sbin/arp -a -n' (the -n returns the IP address rather than the
name). I don't think that there is any way to find the IP address of
an arbitrary MAC device which isn't on the current network.
