The built-in command-line utility named ____ (short for 'name server lookup') is used in Windows to directly query Domain Name System (DNS) servers for resource records.

The lab instructs students to open Command Prompt and run `nslookup` with a domain name or IP address as the argument. The utility sends a DNS query and displays the response, making it useful for checking whether records were created and whether the client is querying the intended server. It does not test whether a host at the returned address is active. **Key takeaway:** `nslookup` provides a direct way to inspect DNS query results from Windows.\n\n**Glossary:** **DNS query**: A request for information from the Domain Name System. **Argument**: A value supplied to a command, such as a name or address.
