Using NSLookup

NSLookup is a command-line tool used to determine information about the DNS. NSLookup is available in Windows NT 4.0 (Service Pack 4 and above), Windows 2000, and Windows XP. When NSLookup is run without options, it displays the name and IP address of the default DNS server before displaying a DNS prompt. Enter the name of a Web site or server to determine its IP address; enter the IP address of a Web site or server to determine its name . Enter a question mark ( ? ) at the prompt to see more options; type exit and then press Enter to exit the program.
