An AAAA record is an Internet protocol address in the recently launched IPv6 format and it comprises of 8 groups of hexadecimal numbers, as opposed to the IPv4 IPs, which include 4 groups of numbers between 1 and 255. A good example of an IPv6 address would be 3014:0d43:23a3:2354:1320:8f3b:2635:3254 and with this format the amount of IPs that can be created is many times larger than the number of the IPv4 addresses. Each and every domain name has its website hosting server IP as a record and in essence, this unique record instructs the domain where the Internet site for it is located. Depending on the system that the service provider employs, the record is going to be called A (IPv4) or AAAA (IPv6). Changing this record enables you to host your site with one provider and your emails with a different one, so if you choose to use this sort of redirection to forward a domain name to a server that uses an IPv6 address, you'll have to set up an AAAA record for it.
