Ping is a computer network administration utility used to test the reachability of a host on an Internet Protocol (IP) network and to measure the round-trip time for messages sent from the originating host to a destination computer.

Ping is a computer network administration utility used to test the reachability of a host on an Internet Protocol (IP) network and to measure the round-trip time for messages sent from the originating host to a destination computer. The ping utility uses the network protocol, which is often filtered by firewalls, so its usefulness is usually limited in corporate environments.

Examples

ping -n 5 www.example.com #pings 5 times the server named www.example.com

A domain name or IP address can be used.
