ICMP (Internet Control Message Protocol)

ICMP is at the same Protocol layer as IP, its purpose is to transmit information needed to control IP traffic. It is used mainly to provide information about routes to destination addresses. ICMP redirect messages inform hosts about more accurate routes to other systems, whereas ICMP unreachable messages indicate problems with a route. Additionally, ICMP can cause TCP connections to terminate gracefully if the route becomes unavailable. The ping command is a commonly-used ICMP-based service.
