Usually you don't need the MAC address directly - except perhaps to improve the documentation in a large network.

If you know a device's IP address, you can do a pingcommand; before and after, compare the ARP cache - the one that shows assignments of IP addresses to MAC addresses. In Windows, the steps would be more or less like this:

  • Open a command window
    • arp -d * (this will delete the ARP cache)
    • arp -a (this will show the ARP cache)
    • ping ... (this will connect to the IP address you specify)
    • arp -a (show the ARP cache again. Compare with the previous one.)
