An AAAA record is an Internet protocol address within the recently introduced IPv6 format and it comprises of 8 different sets of hexadecimal numbers, as opposed to the IPv4 IPs, that include 4 sets of digits between 1 and 255. An example of an IPv6 address is 3014:0d43:23a3:2354:1320:8f3b:2635:3254 and in this format the amount of IPs which can be created is many times bigger than the number of the IPv4 addresses. Each and every domain has its web hosting server IP address as a record and in essence, this record tells the domain where the website 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 site with one company and your emails with another, so if you choose to use this type of redirection to point a domain name to a server that uses an IPv6 address, you will have to set up an AAAA record for it.
