An AAAA record is an Internet protocol address within the recently presented IPv6 format and it is made up of eight different groups of hexadecimal numbers, as opposed to the IPv4 IPs, that include four sets of digits 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 bigger than the number of the IPv4 addresses. Each domain has its website hosting server Internet protocol as a record and in essence, this record informs the domain where the website for it is located. Depending on the system that the service 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 company and your email messages with a different one, so if you decide to use this kind of redirection to forward a domain to a server that uses an IPv6 address, you'll need to set up an AAAA record for it.
