An AAAA record is an Internet protocol address within the newly introduced IPv6 format and it is comprised of 8 different sets of hexadecimal digits, unlike the IPv4 IPs, which include four groups of digits in 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 which can be created is many times greater than the number of the IPv4 addresses. Every domain has its web hosting server Internet protocol as a record and in essence, this unique record informs the domain where the website for it can be found. Depending on the system that the service provider employs, the record will 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 decide to use such a redirection to forward a domain to a server that uses an IPv6 address, you'll need to create an AAAA record for it.
