What is an AAAA Record? IPv6 Address Mapping Setup
The AAAA record (or quad A record) points your hostname to an IPv6 address. The record AAAA specifies IP address (IPv6) for a given host. In other words, it resolves a domain name (or points the domain name) to the correct location by means of the IPv6 address
At present days, the DNS AAAA record is not as popular as the A record. Yet, its implementation is rapidly increasing as the adoption of IPv6 is expanding. The trend shows that IPv6 will become the most commonly used IP address version in the future.
The AAAA record has the following look in your ClouDNS Control Panel:
Host:--------------------------Type:--------------------Points to:------------------------TTL
hostname.com--------AAAA-----------------ipv6:of:your:web::site----------1 Hour
