Which command-line utility can be used to query DNS for a specific server?

The command-line utility that is used to query DNS for a specific server is nslookup. This tool enables users to interact directly with DNS servers to obtain domain name resolution information. With nslookup, one can perform tasks like finding out the IP address associated with a specific domain name or retrieving DNS records for that domain.

By entering a domain name or the IP address of a DNS server, nslookup provides detailed responses that include information such as the server's name, address records, and more. This is particularly useful for troubleshooting DNS-related issues or verifying DNS configurations.

The other utilities mentioned serve different purposes. For instance, tracert is used to trace the route packets take to reach a network host, ipconfig is designed to display network configuration settings for Windows-based systems, and netstat provides information about active network connections and ports. Therefore, nslookup is uniquely suited for querying DNS information.
