A broadcast ping
 	ping -b 255.255.255.255
might get you some useful information, but 
I think you are looking for a "sniffer" rather than a "scanner".
Since you don't know what addresses you are interested in,
you can't sacan them. You need to listen/sniff for traffic
perhaps encouraging it first, which is what the btroadcast does.

The interface will need to be in "promiscuous" mode,
the right tool will do that for you provided you are root.
