The ping command just repeats forever until you press CTRL + C to stop it. In general, the further away the machine is (or the slower the network it’s connected to), the higher the ping times will be. The items of particular interest are the IP address (which is the dotted decimal address in four parts that identifies a machine on the network) and the response time in milliseconds, which is how long the ping took to complete. Something akin to the following should be displayed: Use the Ping command in Terminal to see all the devices present on your local network Just type ping (and hit Enter) or any other website address and you should see some results appear that indicate the website (or individual server) is responding. Once Terminal is open, you can try out the ping command by typing an example at the command prompt. The first thing to do is open Terminal from within the Applications -> Utilities folder, or just type Terminal into Spotlight ( CMD + SPACEBAR) and click on the icon when it’s found.
