ARP

ARP, or Address Resolution Protocol, is used to map an IP address to a physical MAC address on a local network. When a device wants to communicate with another device on the same network, it uses ARP to discover which MAC address corresponds to a known IP address. The result is stored temporarily in an ARP cache to speed up future lookups.
