From LedHed's Wiki
An ARP table maps IP addresses to MAC addresses.
Sometimes you only know the MAC address of a device, but there is no way to ping a MAC address.
Fortunately you can manually add entries to the local ARP table.
arp -S 10.10.10.10 00-fa-de-13-37-oo
Now you can effectively ping the device because you know its IP address. One caveat, you must ping buffer size to 113:
ping 10.10.10.10 -l 113
