Explanation
ARP resolves a known IP address (Layer 3) to its corresponding MAC address (Layer 2) so that data can be delivered on the local network segment. A device broadcasts an ARP request asking 'who has this IP?' and the owner replies with its MAC address. RARP does the opposite - it resolves a known MAC to an IP address. ICMP handles error and diagnostic messaging, and UDP is a transport-layer protocol, neither of which perform address resolution.
