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 ISP’s 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
Clicks
. 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 you know. See Figure 46.
Figure 46. Using the nslookup utility
There may be several addresses associated with an Internet name. This is
common for web sites that receive heavy traffic; they use multiple, redundant
servers to carry the same information.
To exit from the nslookup utility, type
exit
and press
<Enter>
at the command
prompt.
