ARP (Address Resolution Protocol) is used on a LAN to map IP addresses to physical MAC addresses.
Technically, this is not specific to FreeBSD, but if you're using your FreeBSD box as a gateway, this is something that you'll need know (also how to clear the ARP cache on your switch, if you're on a switched network).
