Address Discovery and Binding (ARP)

Address Discovery and Binding (ARP). ARP binds high-level IP addresses to low-level physical addresses. Address binding software forms a boundary between higher layers of protocol software, which use IP addresses, and lower layers of device driver software, which use hardware addresses.
