An AAAA record is an IP in the recently released IPv6 format and it is made up of 8 different groups of hexadecimal numbers, in contrast to the IPv4 IPs, which include 4 groups 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 with this format the number of IPs that may be created is many times higher than the number of the IPv4 addresses. Each and every domain name has its website hosting server Internet protocol as a record and in essence, this unique record informs the domain address where the site for it is located. Depending on the system the service provider uses, the record is going to be called A (IPv4) or AAAA (IPv6). Changing this record allows you to host your site with one provider and your e-mails with a different one, so if you decide to use such a redirection to point a domain name to a server that uses an IPv6 address, you'll have to create an AAAA record for it.
