Address resolution protocol is used to find the MAC address or hardware address from destination IP address through ARP request by network layer.
ARP is the acronym for Address Resolution Protocol. It is an internet protocol that gets the MAC address of a host or node and creates a local db that maps the MAC address to the hosts IP address. ARP needs the IP because IP must have the address of a destination host before it can direct data to it.
