An AAAA record is an IP in the recently released IPv6 format and it is made up of 8 groups of hexadecimal numbers, as opposed to the IPv4 IPs, which feature 4 sets 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 total number of IPs that may be created is many times larger than the number of the IPv4 addresses. Every domain name has its website hosting server Internet protocol as a record and in essence, that record instructs the domain name where the website for it is located. Depending on the system which the company employs, the record will be called A (IPv4) or AAAA (IPv6). Changing this record permits you to host your website with one company and your email messages with a different one, so if you choose to use such a redirection to forward a domain address to a server that uses an IPv6 address, you'll need to create an AAAA record for it.
