7.1 Diagnosing problems using IP utilities
7.1.1 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 45.
Figure 41. Using the ping utility
If the target computer cannot be located, you will receive the message “Request
