An AAAA record maps a domain name to the IPv6 of the computer hosting the domain. An AAAA record is used for finding the IP address of a computer which is connected to internet from a name. Like the A-record, an AAAA-record (also known as quad A-record) maps the name of your domain to an IP address. On one hand, the A-record works with IPv4 whereas the AAAA-record works with IPv6.
