What is a DNS Lookup?
The Domain Name System (DNS) is a hierarchical, decentralised naming system for computers, services, and other internet resources. A DNS lookup queries these records to translate domain names into the network information needed to reach them.
Record types
- A — Maps a domain to an IPv4 address
- AAAA — Maps a domain to an IPv6 address
- MX — Mail exchange servers for email delivery
- TXT — Arbitrary text, used for SPF, DKIM, DMARC
- CNAME — Canonical name alias for another domain
- NS — Authoritative name servers for the domain
