What is the primary use of Nslookup in network administration?

• A. Resolve domain names to IP addresses
• B. Scan open ports
• C. Crack passwords
• D. Enumerate users

Answer: (A)

Nslookup is a network administration tool used to query the Domain Name System to translate domain names into IP addresses. By querying DNS servers, it retrieves the A records that map a domain to its IPv4 address (and AAAA for IPv6), which helps verify that name resolution is functioning and to diagnose DNS configuration issues. It can also inspect other DNS records like MX or NS to understand mail delivery or delegation settings. This makes resolving domain names to IP addresses its primary use. Tools for port scanning, password cracking, or user enumeration perform different tasks and require other utilities; Nslookup does not perform those activities.
