Detailed explanation-1: -ARP works between Layers 2 and 3 of the Open Systems Interconnection model (OSI model). The MAC address exists on Layer 2 of the OSI model, the data link layer. The IP address exists on Layer 3, the network layer.
Detailed explanation-2: -ARP is a protocol used in all local area networks(LAN’s) and is used to resolve network layer(Layer 3 in the OSI Model) addresses into data link layer(Layer 2 in the OSI) addresses, a crucial process in all networks.
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.
