An AAAA record is an Internet protocol address in the newly launched IPv6 format and it is made up of eight sets of hexadecimal numbers, as opposed to the IPv4 IPs, which feature 4 groups of digits in between 1 and 255. An illustration of an IPv6 address would be 3014:0d43:23a3:2354:1320:8f3b:2635:3254 and in this format the amount of IPs that could be created is many times greater than the number of the IPv4 addresses. Each and every domain name has its hosting server Internet protocol as a record and in essence, that record informs the domain address where the site for it is located. Depending on the system that the provider employs, the record is going to be called A (IPv4) or AAAA (IPv6). Changing this record permits you to host your site with one provider and your e-mails with another, so if you decide to use this type of redirection to point a domain to a server that uses an IPv6 address, you'll need to set up an AAAA record for it.
