I wonder what is the easiest and fastest way to detect all machines in
the current subnet from one of the machines and get their MAC-adresses.
My first approach would be to ping each possible adress and then read
the arp-table for valid mac's.
But assuming my limited knowledge of arp and other protocol-layers I
guess there are much better ways.
Trying to do this from a client on the network is an error prone way.
You will never be guaranteed to find all of the hosts.
A "better" way is to query the switch itself. Many switches
will have the ability to get this information from the MIB via
SNMP. That's the "better" way.
