Address Resolution Protocol

* 1protocol which supplies addresses to workstations on a local area network* A Transmission Control Protocol/ Internet Protocol ( TCP/IP) protocol that dynamically binds a Network-Layer IP address to a Data-Link-Layer physical hardware address, eg, Ethernet address* &lt networking, protocol&gt (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
