An AAAA record is an Internet protocol address within the newly launched IPv6 format and it is made up of 8 sets of hexadecimal numbers, as opposed to the IPv4 IPs, which include four 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 with this format the total number of IPs that can be created is many times bigger than the number of the IPv4 addresses. Every domain name has its hosting server Internet protocol as a record and in essence, this unique record informs the domain where the website for it is. Depending on the system which the company employs, the record is going to be called A (IPv4) or AAAA (IPv6). Changing this record enables you to host your site with one company and your email messages with another, so if you choose to use such a redirection to point a domain name to a server that uses an IPv6 address, you will need to set up an AAAA record for it.
