necessary to find the hardware address of a router on the local area network through ARP, and then send the packet to this router so that the router forwards the packet to the next network. The rest of the work is done by the next network. the resolution from the IP address to the hardware address is automatic, and the user of the host is unaware of this address resolution process. The ARP protocol automatically resolves the IP address to the hardware address required by the link layer as long
