An AAAA record is an Internet protocol address in the freshly launched IPv6 format and it is comprised of 8 sets of hexadecimal digits, as opposed to the IPv4 IPs, which include 4 groups of numbers between 1 and 255. An illustration of an IPv6 address would be 3014:0d43:23a3:2354:1320:8f3b:2635:3254 and with this format the number of IPs that can be created is many times higher than the number of the IPv4 addresses. Each and every domain name has its hosting server IP address as a record and in essence, this unique record tells the domain where the Internet site for it is located. Depending on the system which the provider employs, 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 this sort 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.
