• Ping - This diagnostic tool troubleshoots connectivity, reachability, and name resolution
to a given host or gateway by using the Internet Control Message Protocol (ICMP)
protocol's mandatory Echo Request datagram to elicit an ICMP Echo Response from a
host or gateway. You can use ping to test both numeric IP address or domain name. If
pinging the IP address is successful, but pinging the domain name is not, you might have
a name resolution problem. In this case, ensure that the domain name you are specifying
can be resolved by using Domain Name System (DNS) queries.
