Short for AppleTalk Address Resolution Protocol, a protocol for mapping a device’s physical hardware address to a temporary Appletalk network-assigned address in Macintosh computer LANs. When a protocol stack sends a data packet, the protocol address specifies the destination. The data link layer relies on AARP to translate the protocol address into the hardware address of the destination node.
