Using ping

Another useful command is ping. It can be used at the command line to send a data packet to any IP address on the network and thereby check connectivity. For example, to see whether your server is connecting to a computer with an IP address 192.5.6.1, you would type ping 192.5.6.

If the ping packet reaches the other computer, you get an echo response letting you know that the computer is out there. If it does not reach the computer, you get a request time out, meaning the packet failed to reach the specified destination and did not “bounce” back.
