What Is a DNS Lookup?
A DNS (Domain Name System) lookup translates human-readable domain names like example.com into IP addresses and other records that computers use to route traffic. This tool queries public DNS servers to retrieve the records associated with any domain.

- AAAAMaps a domain to an IPv6 address
- CNAMEAlias that points to another domain
- MXMail exchange servers for receiving email
