An AAAA record is an IP within the freshly introduced IPv6 format and it comprises of 8 groups of hexadecimal numbers, unlike the IPv4 IPs, which include 4 sets of numbers between 1 and 255. A good example of an IPv6 address is 3014:0d43:23a3:2354:1320:8f3b:2635:3254 and in this format the number of IPs that could be created is many times larger than the number of the IPv4 addresses. Every domain name has its web hosting server Internet protocol address as a record and in essence, this unique record informs the domain name where the site for it is. Depending on the system the provider uses, the record will be called A (IPv4) or AAAA (IPv6). Changing this record enables you to host your site with one provider and your email messages with another, so if you decide to use such a redirection to forward a domain name to a server that uses an IPv6 address, you'll need to set up an AAAA record for it.
