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
