What Is a DNS Lookup?
A DNS lookup (or DNS resolution) is the process of converting a human-readable domain name like example.com into a machine-readable IP address, or retrieving other DNS records associated with the domain. The Domain Name System (DNS) acts like the phonebook of the internet — it tells your browser which server to connect to when you type a domain name.
DNS Record Types
- A (Address) — Maps a domain to an IPv4 address
- AAAA (IPv6 Address) — Maps a domain to an IPv6 address
- CNAME (Canonical Name) — Aliases one domain to another
- MX (Mail Exchange) — Specifies mail servers for the domain
- NS (Name Server) — Lists authoritative name servers
- TXT (Text) — Stores arbitrary text, often for email security (SPF, DKIM, DMARC)
- SOA (Start of Authority) — Contains admin info about the DNS zone
- SRV (Service) — Specifies services like SIP or LDAP
