AAAA is a domain name record, that's essentially the IPv6 address of the web server where the domain is hosted. The IPv6 system was intended to replace the existing IPv4 system in which every single IP is made up of 4 sets of decimal numbers ranging from 1 to 255 e.g. 5.168.208.143. However, an IPv6 address features 8 groups of 4 hexadecimal digits - which range from 0 to 9 and from A to F. The main reason for this modification is the tremendously smaller range of unique IPs the current system supports as well as the rapid increase of gadgets which are connected to the Internet. A good example of an IPv6 address is 2101:1f34:32e2:2415:1365:4f2b:2553:1345. If you'd like to point a domain to a machine which uses such an address, you will have to create an AAAA record for it, not the widespread A record, which is an IPv4 address. Both records have the very same function, yet different notations are used, in order to differentiate the two types of addresses.
AAAA Records in Shared Hosting
If you are using a service through a third-party provider and you have to set up an AAAA record to direct a domain name or a subdomain to their system, you'll be able to do that with a few mouse clicks via the Hepsia CP, included with all our shared hosting packages. As soon as you log in, you have to proceed to the DNS Records section where you will find all records for every domain or subdomain hosted inside the account. Creating a new record is as simple as clicking on a button, picking the type from a drop-down options menu, that is to be AAAA in this case, and then entering the value, or the actual IPv6 address, within a text box. As an additional option you can modify the TTL value (Time To Live), that determines how long the record is functioning after you change it or erase it in the future. The new AAAA record will be live in only an hour and will propagate around the world an hour or two later, so the hostname for which you have created it will start directing to the new web server.
