Diagnosing Problem using IP Utilities
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 76.
Figure 76. Using the ping Utility
If the target computer cannot be located, you will receive the message “Request timed
out.”
Using the ping command, you can test whether the path to the ROUTER is working (using
the preconfigured default LAN IP address 192.168.1.1) or another address you assigned.
You can also test whether access to the Internet is working by typing an external address,
such as that for www.yahoo.com (216.115.108.243). If you do not know the IP address of
a particular Internet location, you can use the nslookup command, as explained in the
following section.
From most other IP-enabled operating systems, you can execute the same command at a
command prompt or through a system administration utility.
