An AAAA record is an IP address within the freshly introduced IPv6 format and it consists of 8 sets of hexadecimal digits, unlike the IPv4 IPs, which feature four groups of numbers in between 1 and 255. An illustration of an IPv6 address would be 3014:0d43:23a3:2354:1320:8f3b:2635:3254 and with this format the number of IPs that may be created is many times bigger than the number of the IPv4 addresses. Each and every domain has its web hosting server IP as a record and in essence, this unique record tells the domain where the Internet site for it is located. Depending on the system the company uses, the record is going to be called A (IPv4) or AAAA (IPv6). Changing this record will allow you to host your Internet site with one company and your emails with another, so if you choose to use this type of redirection to point a domain name to a server that uses an IPv6 address, you'll have to create an AAAA record for it.
