An AAAA record is an IP in the newly presented IPv6 format and it is made up of 8 sets of hexadecimal numbers, as opposed to the IPv4 IPs, which include four sets of numbers in between 1 and 255. An illustration of an IPv6 address is 3014:0d43:23a3:2354:1320:8f3b:2635:3254 and in this format the amount of IPs that may be created is many times greater than the number of the IPv4 addresses. Each domain has its hosting server Internet protocol address as a record and in essence, this record informs the domain address where the site for it is located. Depending on the system that the company uses, the record is going to be called A (IPv4) or AAAA (IPv6). Changing this record allows you to host your site with one provider and your emails with a different one, so if you decide to use this sort of redirection to forward a domain name to a server that uses an IPv6 address, you will have to set up an AAAA record for it.
