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 in 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, and then click Run. In the Open text box, type the following:

nslookup

Click

. A Command Prompt window displays with a bracket prompt (>). At the

prompt, type the name of the internet address your are interested in, such as
www.microsoft.com.
The window will display the associate IP address, if known, as shown in Figure 77.

Figure 77. 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 at the command prompt.
