An AAAA record is an IP within the newly presented IPv6 format and it consists of eight different groups of hexadecimal numbers, as opposed to the IPv4 IPs, which feature 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 total number of IPs that could be created is many times higher than the number of the IPv4 addresses. Every single domain name has its web hosting server Internet protocol address as a record and in essence, this record informs the domain name where the site 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 allows you to host your Internet site with one provider and your emails 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 have to set up an AAAA record for it.
