Understanding DNS Records

The Domain Name System (DNS) is like the internet's phonebook. It translates human-readable domain names (like google.com) into machine-readable IP addresses. This tool lets you query that system for different types of information.

Common Record Types

  • A Record: Maps a domain to an IPv4 address (e.g., 172.217.6.142).
  • AAAA Record: Maps a domain to a more modern IPv6 address.
  • MX Record: (Mail Exchanger) Specifies the mail servers responsible for accepting email for the domain.
  • TXT Record: Allows administrators to insert arbitrary text. Often used for email security (SPF, DKIM) and domain verification.
  • CNAME Record: (Canonical Name) Forwards one domain to another.
  • NS Record: (Name Server) Indicates which DNS servers are authoritative for the domain.
