An AAAA record is an IP address within the freshly launched IPv6 format and it is made up of eight different groups of hexadecimal numbers, unlike the IPv4 IPs, which feature four groups of numbers between 1 and 255. An example of an IPv6 address is 3014:0d43:23a3:2354:1320:8f3b:2635:3254 and in this format the sheer number of IPs which can be created is many times higher than the number of the IPv4 addresses. Every domain name has its hosting server Internet protocol as a record and in essence, that record informs the domain address where the website for it can be found. Depending on the system the service provider uses, the record will be called A (IPv4) or AAAA (IPv6). Changing this record allows you to host your site with one provider and your emails with another, so if you decide to use this sort of redirection to forward a domain address to a server that uses an IPv6 address, you'll have to create an AAAA record for it.
