Ping: The Network Troubleshooter's Favorite Tool

Segment 4 of 6

        

The simplest use of - "ping" - requires that you know the IP address of your own computer's primary network connection. You can always learn the IP address(s) of your own network interfaces by issuing the - ipconfig - command as shown here:

You can learn more about IP addresses by reviewing other movies here at AskMisterWizard.com (especially the one entitled "Configuring Your Internet Connection Part 1: the Dynamic Host Configuration Protocol"). The resulting command dialog should look a lot like this:

If your own computer is properly configured for Internet access, it's interface will respond to the - "ping" - message with a brief, return message of its own, as if to say - "I received your ping message, and this is my response." The ping utility will immediately display a summary, including information on the time interval between sending each outgoing message and receipt of the corresponding response. When pinging your own local network interface, the time interval (usually expressed in milliseconds), should be very short, as illustrated here.

You can interpret that message as confirmation that your own network interface, inside your own computer, is working as expected.
