Which command-line tool can you use to perform DNS name resolution from Windows?

• A. ipconfig
• B. nslookup
• C. ping
• D. tracert

Answer: (B)

DNS name resolution is about translating a domain name into its IP address by querying a DNS server. The tool designed specifically for this purpose on Windows is nslookup. It is built to perform DNS lookups, letting you query the default DNS server or specify another one, and to request different record types (such as A, AAAA, MX, or NS). For example, you can run a simple lookup to see the IP address(es) for a domain, and you can switch to interactive mode to run multiple queries or adjust the query type as needed. While other commands touch DNS in some way—ipconfig shows DNS server settings, ping resolves a name to an address as part of its normal operation, and tracert may perform a name resolution to begin tracing—none are primarily designed for performing and inspecting DNS queries the way nslookup is.
