ping
Ping is a command you can use to check whether your PC can recognize other computers on your network and
the Internet. A ping command sends a message to the computer you specify. If the computer receives the messa-
ge, it sends messages in reply. To use it, you must know the IP address of the computer with which you are trying
to communicate.
On Windows-based computers, you can execute a ping command from the Start menu. Click the Start button, and
then click Run. In the Open text box, type a statement such as the following:
ping 10.0.0.2
