An AAAA record is an Internet protocol address within the freshly released IPv6 format and it is comprised of 8 different groups of hexadecimal numbers, in contrast to the IPv4 IPs, which feature 4 sets of digits in between 1 and 255. A good example of an IPv6 address would be 3014:0d43:23a3:2354:1320:8f3b:2635:3254 and in this format the total number of IPs that could be created is many times higher than the number of the IPv4 addresses. Each domain has its hosting server Internet protocol address as a record and in essence, this unique record instructs the domain name where the site for it can be found. Depending on the system the provider employs, the record is going to be called A (IPv4) or AAAA (IPv6). Changing this record will allow you to host your Internet site with one provider and your emails with another, so if you decide to use such a redirection to forward a domain to a server that uses an IPv6 address, you'll need to set up an AAAA record for it.
