Describe the types of programs that use ICMP.
What will be an ideal response?
Programs that use ICMP only need to send a single packet, therefore used for such mundane purposes as disconnect messages, which we see as a "host unreachable" message. The ping program uses ICMP, sending a single ICMP packet, called an echo request, to the IP address specified as a parameter of the command. The target machine responds with an echo reply via ICMP.
