8.2.2 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 in 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:

To exit from the nslookup utility, type exit and press [Enter] at the command prompt.
