The Internet Control Message Protocol (ICMP) is one of the main protocols of the Internet Protocol Suite. It is used by network devices, like routers, 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 can also be used to relay query messages–(wikipedia).
ICMP commonly use by ping and traceroute command on your computer,
Ping : method to know whether one host (computer or other network appliance which has IP address) is live.
Traceroute : which path taken to a destination IP address or domain name
Because of the innocent of ICMP, the good purpose of ICMP has been miss use by hacker. Many hacker using technique based on ICMP protocol like Ping Sweep.
