This lesson explains Address Resolution Protocol (ARP) to you. Network devices use ARP to find the MAC address of the IP address they want to reach.
4.4 ARP Packet Format. Figure 4.3 shows the format of an ARP request and an ARP reply packet, when used on an Ethernet to resolve an IP address. (ARP is general enough to be used on other networks and can resolve addresses other than IP addresses.
