What is a DNS AAAA Record? | Definition, Function & Example

A DNS AAAA Record (pronounced “quad-A”) is a type of DNS record that maps a domain name (like example.com) to an IPv6 address (e.g., 2001:0db8:85a3::8a2e:0370:7334). It is the IPv6 equivalent of the A record used for IPv4.

Key Functions of a DNS AAAA Record:

  • Enables IPv6 support: Directs traffic to servers with IPv6 addresses.
  • Prepares websites for the future: Ensures compatibility as the internet transitions to IPv6.
  • Allows dual-stack hosting: Can be used alongside A records for comprehensive IP coverage.

Example of a DNS AAAA Record:

example.com.   IN   AAAA   2001:0db8:85a3::8a2e:0370:7334

Best Practices for DNS AAAA Records:

  • Configure AAAA records if your server supports IPv6.
  • Maintain both A and AAAA records for full compatibility (dual stack).
  • Test DNS propagation and ensure IPv6 accessibility using tools like DNS Checker or Google's IPv6 test.
