An AAAA record is an Internet protocol address within the freshly introduced IPv6 format and it is comprised of eight groups of hexadecimal digits, in contrast to the IPv4 IPs, that include 4 sets of numbers between 1 and 255. A good example of an IPv6 address would be 3014:0d43:23a3:2354:1320:8f3b:2635:3254 and in this format the number of IPs that can be created is many times bigger than the number of the IPv4 addresses. Each domain has its hosting server Internet protocol address as a record and in essence, this unique record tells the domain where the website for it can be found. Depending on the system that the service provider uses, the record will be called A (IPv4) or AAAA (IPv6). Changing this record enables you to host your website with one provider and your e-mails with a different one, so if you choose to use this type of redirection to point a domain to a server that uses an IPv6 address, you'll need to create an AAAA record for it.
