AAAA Record
A DNS record that maps a domain name to an IPv6 address.
An AAAA record (pronounced "quad-A") works exactly like an A record, but for IPv6 addresses instead of IPv4. IPv6 addresses are longer (like 2606:4700::6810:85e5) and were created because the world is running out of IPv4 addresses. If your server supports IPv6, adding an AAAA record ensures it is reachable on the modern internet. Many websites have both A and AAAA records so they work on both IPv4 and IPv6 networks.
