What is DNS?

The Domain Name System (DNS) is like the internet's phone book. It translates human-readable domain names (like google.com) into IP addresses that computers use to communicate.

Common DNS Record Types

  • A Record: Maps a domain to an IPv4 address
  • AAAA Record: Maps a domain to an IPv6 address
  • MX Record: Specifies mail servers for the domain
  • TXT Record: Holds text data, often used for SPF, DKIM, and domain verification
  • CNAME Record: Creates an alias from one domain to another
  • NS Record: Specifies the authoritative name servers for the domain

Pro Tip: When troubleshooting email delivery issues, check your MX, SPF (TXT), and DKIM records. Use our Domain Health Check for a comprehensive analysis.
