An AAAA record is an IP address within the freshly presented IPv6 format and it is comprised of 8 different sets of hexadecimal numbers, unlike the IPv4 IPs, which include 4 groups of numbers in between 1 and 255. A good example of an IPv6 address is 3014:0d43:23a3:2354:1320:8f3b:2635:3254 and in this format the number of IPs that could be created is many times larger than the number of the IPv4 addresses. Each domain name has its website hosting server Internet protocol address as a record and in essence, that record informs the domain name where the site for it can be found. Depending on the system which the company uses, the record is going to be called A (IPv4) or AAAA (IPv6). Changing this record enables you to host your Internet site with one company and your emails with another, so if you decide to use this kind of redirection to point a domain name to a server that uses an IPv6 address, you'll need to create an AAAA record for it.
