Short for Internet Control Message Protocol, an extension to the Internet Protocol (IP). ICMP supports packets containing error, control, and informational messages. The PING command, for example, uses ICMP to test an Internet connection

The Internet Control Message Protocol (ICMP) is one of the core protocols of the Internet Protocol Suite. It is chiefly used by the operating systems of networked computers to send error messages indicating, for example, that a requested service is not available or that a host or router could not be reached.

ICMP - Internet Control Message Protocol is an integral part of IP (internet protocol). When the datagram cannot reach the destination, ICMP sends the error message to the source. It provides the feedback of the problems in the communication environment.
