14.1 Diagnosing problems using IP utilities

14.1.1 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 <OK>. You can substitute any private IP address you know on your

LAN or a public IP address for an Internet site.
If the target computer receives the message, a Command Prompt window

appears as shown in Figure 14.1.
