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 switch is working
(using the pre-configured 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.
7.1.2 nslookup
You can use the nslookup command to determine the IP address associated
with an Internet site name. You specify the common name, and the nslookup
command looks up the name on your DNS server (usually located with your
ISP). If that name is not an entry in your ISPʼs DNS table, the request is then
referred to another higher-level server, and so on, until the entry is found. The
server then returns the associated IP address.
On Windows-based computers, you can execute the nslookup command from
the Start menu. Click the Start button, then click Run. In the Open text box, type
the following:
nslookup
Click OK. A Command Prompt window displays with a bracket prompt (>). At
the prompt, type the name of the Internet address you are interested in, such as
www.absnews.com.
The window displays the associate IP address, if known. See Figure 62.
