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 64.
Figure 64. 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.
