AAAA is a domain record, that is basically the IPv6 address of the web server where the domain name is hosted. The IPv6 system was intended to replace the current IPv4 system in which each and every Internet protocol address comprises of four sets of decimal numbers which range from 1 to 255 e.g. 18.104.22.168. On the other hand, an IPv6 address features eight groups of 4 hexadecimal digits - which range from 0 to 9 and from A to F. The cause of this change is the considerably smaller selection of unique IPs the present system supports as well as 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 direct a domain to a web server which uses this type of an address, you will need to set up an AAAA record for it, and not the commonly used A record, that is an IPv4 address. The two records have the exact same function, but different notations are used, in order to identify the two sorts of addresses.
