Given the IP address of a destination on the local LAN, how does a TCP/IP host discover the MAC address in order to send an Ethernet frame?
What will be an ideal response?
If a TCP/IP host knows the IP address, but does not know the MAC address of a destination computer on the local network, it can use address resolution protocol (ARP) to discover the MAC address. To do this, it broadcasts a special packet, containing its own IP address and MAC address and the IP address of the destination computer. The computer with the IP address matching the destination IP address will respond with an ARP packet containing its IP address as well as its MAC address.
