Detailed explanation-3: -ARP is a protocol used by the Internet Protocol (IP) [RFC826], 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 Open Systems Interconnection (OSI) network and OSI link layer.
