What is a DNS Lookup?

A DNS Lookup queries the DNS (Domain Name System) records of a domain. DNS is like the phone book of the internet – it translates domain names like "example.com" into IP addresses. Different record types serve different purposes: A records point to IPv4 addresses, AAAA records to IPv6, MX records define mail servers, NS records name the authoritative nameservers, and TXT records contain text data like SPF or verification codes.
