About DNS Records

The Domain Name System (DNS) is the internet's phonebook, translating human-readable domain names into IP addresses. DNS records contain essential configuration for how a domain behaves across email, web, security, and services.

Common Records

A/AAAA - Map domain to IPv4/IPv6 addresses
MX - Mail servers for receiving email
TXT - SPF, DKIM, DMARC for email security
NS - Authoritative nameservers
CNAME - Aliases pointing to other domains

Security Records

CAA - Restrict which CAs can issue certificates
DNSKEY/DS - DNSSEC cryptographic keys
TLSA - DANE TLS certificate authentication
SSHFP - SSH host key fingerprints
SRV - Service discovery and endpoints

REST API

Integrate DNS lookups into your applications with our REST API. Query all record types programmatically.
