The only caveat, is that (unless you know the MAC address of every device on your network), you won’t have a clue as to which machine the IP addresses are assigned. You now have a listing of each IP address in use on your LAN. The output of the command will display IP addresses as well as the associated ethernet device ( Figure A).

Most IT admins are familiar with arp, as it is used on almost every platform. The first tool we’ll use for the task is the built-in arp command.
