What is ping?

Ping is a program that sends a series of packets over a network or the Internet to a specific computer in order to generate a response from that computer. The other computer responds with an acknowledgment that it received the packets. Ping was created to verify whether a specific computer on a network or the Internet exists and is connected.

Some have claimed that the word "ping" is actually an acronym for "Packet Internet (or Inter-Network) Groper", deliberately contrived to play on the fact that pinging with a computer is similar to what submariners do with sonar. Both the computer and the submarine's sonar send out a "ping", in the form of either a series of packets or a brief burst of sound. The ping "bounces" off the target and then returns to let you know the target is there.

Ping is both a noun and a verb, e.g., "Ping that computer", or "the router didn't return a ping".

Ping is built into almost every network-capable operating system. To ping a computer, go to a command prompt and enter ping , a space, and then the network or Internet address you wish to contact. For example, enter the following at a Windows XP command prompt:
ping 66.218.71.198

You should get a response similar to this:
pinging 66.218.71.198 with 32 bytes of data: Reply from 66.218.71.198: bytes=32 time<1ms TTL=127 Reply from 66.218.71.198: bytes=32 time<1ms TTL=127 Reply from 66.218.71.198: bytes=32 time<1ms TTL=127 Reply from 66.218.71.198: bytes=32 time<1ms TTL=127 ping statistics for 66.218.71.198: Packets: Sent = 4, Received = 4, Lost = 0 (0% loss), Approximate round trip times in milli-seconds: Minimum = 0ms, Maximum = 0ms, Average = 0ms

Operating systems format their ping results differently. For example, following is what the result looks like from a Linux computer:
ping 66.218.71.198 (66.218.71.198) 56(84) bytes of data. 64 bytes from 66.218.71.198: icmp_seq=1 ttl=254 time=0.644 ms 64 bytes from 66.218.71.198: icmp_seq=2 ttl=254 time=0.510 ms 64 bytes from 66.218.71.198: icmp_seq=3 ttl=254 time=0.584 ms 64 bytes from 66.218.71.198: icmp_seq=4 ttl=254 time=0.535 ms --- 66.218.71.198 PING statistics --- 4 packets transmitted, 4 received, 0% packet loss, time 3000ms rtt min/avg/max/mdev = 0.510/0.568/0.644/0.053 ms

Regardless of the operating system, the results will show the IP address of the computer you're pinging, the round-trip time in milliseconds for each packet, the number of packets sent and received, and the number and percentage of how many packets got lost.
