13.1 Diagnosing Problem using IP Utilities
13.1.1 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
message, 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 192.168.1.1
Click . You can substitute any private IP address on your LAN or a public IP address for an Internet
site, if known.
If the target computer receives the message, a Command Prompt window displays like that shown in Figure
13.1.
