AAAA is a domain address record, that's in essence the IPv6 address of the web server in which the domain name is hosted. The IPv6 system was designed to replace the present IPv4 system where each IP address comprises of four groups of decimal digits between 1 to 255 e.g. 188.8.131.52. In comparison, an IPv6 address includes 8 groups of four hexadecimal numbers - ranging from 0 to 9 and from A to F. The main reason for this transformation is the considerably smaller selection of unique IPs that the present system supports and the speedy increase of gadgets that are connected to the Internet. An illustration of an IPv6 address would be 2101:1f34:32e2:2415:1365:4f2b:2553:1345. If you'd like to forward a domain address to a web server that uses this kind of an address, you have to create an AAAA record for it, not the widely used A record, which is an IPv4 address. Both records deliver the very same function, yet different notations are used, so as to separate the two sorts of addresses.
