AAAA record
also: IPv6 address record
A DNS record that maps a domain name to an IPv6 address, the successor to the A record for IPv4.
An AAAA record is a type of Domain Name System (DNS) record used to associate a fully qualified domain name with an IPv6 address. The four A's represent the four groups of hexadecimal digits in an IPv6 address.
While the traditional A record maps a domain to a 32-bit IPv4 address (like 192.0.2.1), an AAAA record maps it to a 128-bit IPv6 address (like 2001:0db8:85a3::8a2e:0370:7334). Both can coexist for the same domain to support clients using either protocol.
For example, querying dig example.com AAAA would return the IPv6 address(es) for example.com if AAAA records are configured, allowing IPv6-capable clients to connect directly without falling back to IPv4.
