Apple Address Resolution Protocol
AARP

   <networking> (AARP) {Apple}'s system to allow {AppleTalk}
   {protocol} to work over networks other than {LocalTalk}, such
   as {Ethernet} or {Token Ring}.  {AppleTalk} {nodes} announce
   their presence to the network so that other nodes can address
   messages to them.  AARP maps between AppleTalk addresses and
   other schemes.  It is actually a general address mapping
   protocol that can be used to map between addresses at any
   protocol level.
