An AAAA record is an Internet protocol address in the newly launched IPv6 format and it is made up of 8 different groups of hexadecimal numbers, as opposed to the IPv4 IPs, that include 4 groups of digits between 1 and 255. An example of an IPv6 address would be 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. Every single domain has its website hosting server Internet protocol address as a record and in essence, that record tells the domain name where the website for it can be found. Depending on the system that the provider employs, the record is going to be called A (IPv4) or AAAA (IPv6). Changing this record enables you to host your website with one company and your e-mails with a different one, so if you decide to use this sort of 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.
