NSLOOKUP is used to check Domain Name Service (DNS) functionality, to query DNS servers, to verify correct configuration and to troubleshoot errors. The nslookup tool can be used as a single command from the command line or it can be used in interactive mode. There are also websites on the Internet that provide NSLOOKUP services. nslookup is provided with Linux, Unix and WIndows NT systems. It is not installed with Windows 95 or 98.
