Ping is a mechanism to see if a remote host is reachable via an IP network

Ping is used to send an ICMP packet to a remote host. The ICMP type sent is an echo request, and the type the remote host will send back is an echo reply. Some firewalls or hosts may block ICMP, so ping should not be the only tool used for troubleshooting.
