AAAA is a domain record, which is essentially the IPv6 address of the server in which the domain name is hosted. The IPv6 system was introduced to replace the present IPv4 system where each and every Internet protocol address consists of 4 sets of decimal numbers which range from 1 to 255 e.g. 126.96.36.199. However, an IPv6 address features eight groups of four hexadecimal numbers - which range from 0 to 9 and from A to F. The reason behind this modification is the significantly smaller range of unique IPs the current system supports and the quick increase of products that are connected to the world wide web. An example of an IPv6 address is 2101:1f34:32e2:2415:1365:4f2b:2553:1345. If you wish to direct a domain name to a server that uses this type of an address, you will have to create an AAAA record for it, and not the widely used A record, which is an IPv4 address. Both records have the very same function, yet different notations are used, in order to separate the two sorts of addresses.
