An AAAA record is an IP in the newly launched IPv6 format and it consists of 8 different sets of hexadecimal numbers, as opposed to the IPv4 IPs, that include 4 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 in this format the amount of IPs that can be created is many times greater than the number of the IPv4 addresses. Each and every domain name has its website hosting server Internet protocol address as a record and in essence, this unique record informs the domain name where the website for it is. Depending on the system the provider 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 provider and your email messages with a different one, so if you choose to use such a redirection to forward a domain name to a server that uses an IPv6 address, you'll need to create an AAAA record for it.
