Well, finding MAC addresses of other nodes on the same network would
be infeasible. Any thoughts?

usually I am using something like this to check the MAC addresses in networks:

user@localhost:~$ for i in $(seq 1 254); do arping -c1 -D -I eth0
192.168.0.$i | grep reply; done;

Hi,

While this looks simple, there can be many IP subnet being used in the
same broadcast domain. For a small, known, /24 range, doing the thing
you mentioned is ok, but you don't know what other network ranges are
being used on the same network.
