ICMP Statistics
Internet Control Message Protocol (ICMP) is a network layer protocol that transmits
message packets to report errors in processing IP packets. ICMP is therefore an
integral part of the Internet Protocol. ICMP messages may be used to report various
situations, such as when a datagram cannot reach its destination, when the gateway
does not have the buffering capacity to forward a datagram, and when the gateway
can direct the host to send traffic on a shorter route. ICMP is also used by routers to
feed back information about more suitable routes (i.e., the next hop router) to use for
a specific destination.
