AAAA is a domain name record, which is in essence the IPv6 address of the web server where the domain name is hosted. The IPv6 system was intended to replace the existing IPv4 system in which every single IP is made up of 4 groups of decimal digits between 1 to 255 e.g. 5.168.208.143. However, an IPv6 address has eight groups of 4 hexadecimal numbers - ranging from 0 to 9 and from A to F. The reason behind this change is the significantly smaller number of unique IPs which the current system supports and also the fast increase of products that are connected to the Internet. An illustration of an IPv6 address would be 2101:1f34:32e2:2415:1365:4f2b:2553:1345. If you wish to point a domain address to a server which uses this kind of an address, you will need to set up an AAAA record for it, and not the widely used A record, that is an IPv4 address. The 2 records have the same exact function, yet different notations are used, to identify the two types of addresses.
AAAA Records in Shared Hosting
If you need to set up a new AAAA record a domain or subdomain hosted within your shared hosting account, it is not going to take you more than a few basic steps to do that. Our in-house built Hepsia Control Panel is quite intuitive to use and it will enable you to create or modify every single record easily. When you sign in and visit the DNS Records section, where you'll discover all existing records for your domains and subdomains, you will simply have to click on the "New" button, choose AAAA from a small drop-down menu in the pop-up that will appear, enter or paste the required IPv6 address and save the change - it's as easy as that. The new record shall be 100% live within only 1 hour and the hostname which you have created it for will start opening whatever content you have with the other company. If needed, you are also going to be able to modify the TTL (Time To Live) value, which signifies the time in seconds which the new record will be live after you eventually modify it to something different or you simply remove it.
