An AAAA record is an IP address in the freshly released IPv6 format and it consists of eight different sets of hexadecimal numbers, in contrast to the IPv4 IPs, which include four sets of numbers 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 sheer number of IPs that may be created is many times bigger than the number of the IPv4 addresses. Each domain has its web hosting server IP as a record and in essence, that record instructs the domain where the Internet site for it is located. Depending on the system that the provider employs, the record is going to be called A (IPv4) or AAAA (IPv6). Changing this record allows you to host your Internet site with one company and your emails with a different one, so if you choose to use such a redirection to point a domain name to a server that uses an IPv6 address, you will need to create an AAAA record for it.
