Explanation

The RARP protocol sends out a packet, which includes its MAC address and a request to be informed of the IP address that should be assigned to that MAC address. ARP does the opposite by broadcasting a request to find the Ethernet address that matches a known IP address. ICMP supports packets containing error, control, and informational messages (e.g. PING). UDP runs over IP and is used primarily for broadcasting messages over a network.
