How to Use the Ping Command
Ping (Packet Internet Groper) is a command which tests the connection between two network nodes by sending packets to a host and then reporting the time it takes to get a response. The nodes can be in a Local Area Network, Wide Area Network or anywhere on the internet. And you can ping an IP Address or Domain Name.
Enter the word ping, followed by a space, then the domain name/ip address (then hit enter to see your ping output).
If it shows a series of replies, the connection is working. The time shows you how fast the connection is. If you see a "timed out" error instead of a reply, there is a breakdown somewhere between your computer and the domain.
In Windows, select Start-> Programs-> Accessories-> Command Prompt. This will give you a window like the one below. Or click Start and go to Run, type cmd in the box and click OK.
