What is an AAAA Record?
DNS record type that maps a domain name to an IPv6 address.
Detailed Explanation
The AAAA record (quad-A) performs the same function as an A record but for IPv6 addresses. As IPv6 adoption grows, AAAA records become increasingly important. Modern DNS resolvers often query for both A and AAAA records simultaneously, preferring IPv6 when available but falling back to IPv4 if needed.
Examples
- •example.com AAAA 2001:db8::1
- •ipv6.google.com AAAA 2a00:1450:4001:830::200e
- •Dual-stack: example.com has both A and AAAA records
