What Is a DNS Lookup?
A DNS (Domain Name System) lookup queries DNS servers to retrieve the records associated with a domain name. DNS is what translates human-readable domain names (like google.com) into the IP addresses that computers use to communicate. Our tool queries multiple DNS record types in a single request, giving you a complete view of a domain's DNS configuration.
