An AAAA record is an Internet protocol address within the freshly presented IPv6 format and it is comprised of 8 different groups of hexadecimal numbers, in contrast to the IPv4 IPs, which feature 4 groups of digits 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 total number of IPs that could be created is many times greater than the number of the IPv4 addresses. Each and every domain has its website hosting server Internet protocol address as a record and in essence, this unique record informs the domain name where the site for it is. Depending on the system the provider employs, the record will be called A (IPv4) or AAAA (IPv6). Changing this record will allow you to host your site with one company and your emails with another, so if you decide to use such a redirection to forward a domain name to a server that uses an IPv6 address, you will need to set up an AAAA record for it.
