An AAAA record is an IP in the freshly presented IPv6 format and it is comprised of 8 sets of hexadecimal digits, in contrast to the IPv4 IPs, that include four groups of digits in between 1 and 255. An example of an IPv6 address would be 3014:0d43:23a3:2354:1320:8f3b:2635:3254 and in this format the amount of IPs that can be created is many times greater than the number of the IPv4 addresses. Every domain has its website hosting server Internet protocol address as a record and in essence, that record tells the domain name where the website for it is located. Depending on the system which the service provider employs, the record will be called A (IPv4) or AAAA (IPv6). Changing this record permits you to host your site with one provider and your e-mails with another, so if you decide to use this sort of redirection to point a domain to a server that uses an IPv6 address, you will need to set up an AAAA record for it.
