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
