ICMP includes the following services: diagnostic (Echo and Echo Reply messages), delivery error reporting (Destination Unreachable, Time Exceeded, Source Quench, and Redirect messages), router discovery (Router Advertisement and Router Solicitation messages), IP header problems (Parameter Problem message), and address mask discovery (Address Mask Request and Address Mask Reply messages).The ICMP Destination Unreachable-Fragmentation Needed And DF Set message is used for PTMU Discovery. The Ping, Tracert, and Pathping tools provided with Windows Server 2008 and Windows Vista use ICMP messages for diagnostic functions.
