 | | It works by sending ICMP packets to thetarget host and listening for replies; its operation is analogous to active sonar in submarines, in which an operator issues a pulse of energy (a network packet) atthe target, which then bounces from the target and is then received by the operator, hence the name. |
 | | The usefulness of ping in assisting the diagnosis of internet connectivity issues was impaired from late in 2003, when anumber of Internet Service Providers filtered outICMP Type 8 (echo request) messages at their network boundaries. |
 | | The output of ping, and its cousins, generally consists of the packet size used, the host queried, the ICMP sequence number, the time to live, and the latency,with all times given in milliseconds, and times below 10 milliseconds often having low accuracy. |
