AAAA Record

A DNS record that maps a domain to an IPv6 address — the successor to the IPv4 A record.

An AAAA record is a DNS record that maps a domain name to an IPv6 address (128-bit), the successor to IPv4. As IPv4 addresses run out, IPv6 adoption is increasing. An AAAA record works identically to an A record but uses the newer IPv6 format (e.g., 2001:0db8:85a3:0000:0000:8a2e:0370:7334). Modern websites should have both A and AAAA records to serve both IPv4 and IPv6 users.
