🌐 DNS Lookup
Query DNS records for any domain: A, AAAA, MX, NS, TXT, CNAME, SOA, and PTR records. See TTLs and authoritative responses.
What is DNS?
The Domain Name System (DNS) translates human-readable domain names like example.com into IP addresses that computers use to communicate. DNS records define how a domain behaves — where its website is hosted, where email is delivered, and how ownership is verified.
DNS Record Types
| Type | Description |
|---|---|
| A | Maps a domain to an IPv4 address |
| AAAA | Maps a domain to an IPv6 address |
| MX | Specifies mail servers responsible for receiving email |
| NS | Identifies the authoritative name servers for the domain |
| TXT | Holds arbitrary text data, often used for SPF, DKIM, and domain verification |
| CNAME | Creates an alias pointing one domain name to another |
| SOA | Contains administrative information about the zone including serial number and refresh intervals |
