AAAA DNS record is an alternative to A records. You use these records when your server address is in IPv6 format.
What does an AAAA record look like?
* 600 IN AAAA 2A03: 2880: 2110: df07: face: b00c: 0:1.
Example of setting up an AAAA record
You want to point the subdomain blog.mydomain.com to the server at 2A03: 2880: 2110: df07: face: b00c: 0: 1 (IPv6 for Facebook). As you can see, this isn’t a standard IPv4 address (for example 172.16.254.1) like you use in an A record. This is an IPv6 address that you use in an AAAA record.
