What is nslookup?
nslookup is a command-line tool used to query DNS servers and retrieve information about domain name resolution. It allows a network engineer to check what IP address a domain resolves to, which DNS server is being used, and whether DNS records such as A, MX, or CNAME entries are correctly configured. It is an essential tool for diagnosing DNS-related issues, such as a website being unreachable due to a missing or incorrect DNS record.
