- Address Resolution Protocol (ARP) is a protocol for mapping an Internet Protocol address (IP address) to a physical machine address that is recognized in the local network. For example, in IP Version 4, the most common level of IP in use today, an address is 32 bits long.

The address resolution protocol (arp) is a protocol used by the Internet Protocol (IP) [RFC826], specifically IPv4, to map IP network addresses to the hardware addresses used by a data link protocol. The protocol operates below the network layer as a part of the interface between the OSI network and OSI link layer.

Once a common encapsulation mechanism has been selected for Ethernet, hosts must still convert a 32-bit IP address into a 48-bit Ethernet address. The Address Resolution Protocol (ARP), documented in RFC 826, is used to do this.
