An AAAA record is an IP in the recently released IPv6 format and it is made up of eight different sets of hexadecimal numbers, as opposed to the IPv4 IPs, which include four groups of numbers 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 number of IPs that could be created is many times higher than the number of the IPv4 addresses. Each and every domain name has its hosting server Internet protocol as a record and in essence, this unique record instructs the domain name where the website for it is located. Depending on the system the company uses, the record will be called A (IPv4) or AAAA (IPv6). Changing this record allows you to host your Internet site with one company and your e-mails with another, so if you decide to use this sort of redirection to point a domain name to a server that uses an IPv6 address, you'll need to set up an AAAA record for it.
