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 present IPv4 system in which each and every Internet protocol address comprises of four sets of decimal digits which range from 1 to 255 e.g. 126.96.36.199. However, an IPv6 address has 8 sets of 4 hexadecimal numbers - from 0 to 9 and from A to F. The reason for this change is the significantly smaller number of unique IPs that the present system supports and also the speedy increase of gadgets that are connected to the world wide web. An illustration of an IPv6 address is 2101:1f34:32e2:2415:1365:4f2b:2553:1345. If you need to point a domain address to a web 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, that is an IPv4 address. The 2 records have the same exact function, yet different notations are used, so as to distinguish the two sorts of addresses.
