An AAAA record is an IP address in the freshly introduced IPv6 format and it comprises of eight different sets of hexadecimal numbers, in contrast to the IPv4 IPs, which include 4 groups of numbers between 1 and 255. An example of an IPv6 address would be 3014:0d43:23a3:2354:1320:8f3b:2635:3254 and with this format the number of IPs that can be created is many times larger than the number of the IPv4 addresses. Each and every domain has its hosting server IP address as a record and in essence, that record informs the domain where the website for it is located. Depending on the system the provider uses, the record is going to be called A (IPv4) or AAAA (IPv6). Changing this record permits you to host your website with one company and your e-mails with another, so if you choose to use this sort of redirection to forward a domain to a server that uses an IPv6 address, you will have to create an AAAA record for it.
