What (who) is Address Resolution Protocol - definition
Address Resolution Protocol
<networking, protocol> (ARP) A method for finding a host's
Ethernet address from its Internet address. The sender
broadcasts an ARP packet containing the Internet address
of another host and waits for it (or some other host) to send
back its Ethernet address. Each host maintains a cache of
address translations to reduce delay and loading. ARP allows
the Internet address to be independent of the Ethernet address
but it only works if all hosts support it.
ARP is defined in RFC 826.
The alternative for hosts that do not do ARP is {constant
mapping}.
See also proxy ARP, reverse ARP.

Address Resolution Protocol
The Address Resolution Protocol (ARP) is a communication protocol used for discovering the link layer address, such as a MAC address, associated with a given internet layer address, typically an IPv4 address. This mapping is a critical function in the Internet protocol suite.
Terminal Identifier – Address Resolution Protocol
Terminal Identifier – Address Resolution Protocol (TARP) is a protocol defined in Telcordia Technologies (formerly Bellcore) Generic Requirements document GR-253-CORE for SONET and used in OSS to resolve a TL1 TID to a CLNP address (NSAP) of a Network Element (NE). The protocol is used in a number of network devices.
