An AAAA record is an Internet protocol address in the freshly introduced IPv6 format and it is comprised of eight groups of hexadecimal numbers, unlike the IPv4 IPs, that include four groups of digits in between 1 and 255. An example of an IPv6 address is 3014:0d43:23a3:2354:1320:8f3b:2635:3254 and with this format the number of IPs which can be created is many times greater than the number of the IPv4 addresses. Every domain name has its website hosting server Internet protocol address as a record and in essence, this record informs the domain address where the site for it is located. Depending on the system that the service provider employs, the record will be called A (IPv4) or AAAA (IPv6). Changing this record will allow you to host your website with one provider and your email messages with another, so if you choose to use this type of redirection to forward a domain address to a server that uses an IPv6 address, you'll have to create an AAAA record for it.
