In this extremely quick tutorial, I will be showing you how to ping an IP/domain to see if it is online. To do this, will will need to use the Windows Key + R to bring up the run window. If you cant do this, just press start and type in run. This will bring up a box like the one below. In this we will need to type 'ping <ip/domain> -t'. The <ip/domain> is the ip or domain that you would like to ping. The -t on the end means that it will run until it has been cancelled (Ctrl+C).
If you then click Ok, it should then start the ping in cmd.
