A TCP/IP-based protocol that enables a sending station to determine the MAC address of the intended receiving station.

A peer-to-peer protocol used on networks for communications between Macintosh computers.
AppleTolk Address Resolution Protocol (AARP)
An AppleTalk protocol that is used to detect the physical or MAC sublayer addresses of NICs so that they are incorporated in AppleTalk frames; when a Macintosh computer is configured for both AppleTalk and IP, AARP is used to detect physical (MAC) and IP address.
One copy of each frame or packet is sent to all points on a network, regardless of whether of not a node has requested it.
