If you have L2 access to the segment and have any clue as what the ranges
might be, than a simple ARP scan will give you a list of IP/MAC pairs.
Further if you have a clue with respect to connected network ranges, ARP
scanning for these segments will in many cases give you the routers that
do routing to these other segments.
If you are unable to find an ARP scanning tool, I have some alpha grade
perl scripts for the Linux platform if you are interested and not afraid
of rewriting some lines of perl yourself.
