An AAAA record is an IP within the recently launched IPv6 format and it is comprised of eight different sets of hexadecimal numbers, as opposed to the IPv4 IPs, which 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 total number of IPs that can be created is many times larger than the number of the IPv4 addresses. Each and every domain has its web hosting server IP address 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 service provider employs, the record will be called A (IPv4) or AAAA (IPv6). Changing this record allows you to host your website with one provider and your e-mails with another, so if you choose to use such a redirection to point a domain address to a server that uses an IPv6 address, you will have to create an AAAA record for it.
