How the TCP/IP Protocol Works
... Address Recognition Protocol (ARP) • IP address is at network layer, need to map it to the MAC (Ethernet address) link layer address • Use ARP to map 48 bit Ethernet address to 32 bit IP – IP requests MAC address for IP address from local ARP table – If not there, then an ARP request packet for IP ...
