Understanding DNS Records

What is DNS?

The Domain Name System translates human-readable domain names into IP addresses. DNS records control website routing, email delivery, and domain ownership verification.

Why check DNS records?

  • Troubleshoot website connectivity issues
  • Verify email configuration settings
  • Monitor domain security records
  • Audit DNS changes after propagation

Common record types

A   Maps domain to IPv4 address
AAAA   Maps domain to IPv6 address
CNAME   Alias pointing to another domain
MX   Mail servers for email delivery
TXT   Text records for SPF, DKIM, verification
NS   Authoritative nameservers
