An AAAA record is an IP in the recently launched IPv6 format and it is comprised of eight groups of hexadecimal numbers, unlike the IPv4 IPs, which feature four 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 amount of IPs that could be created is many times greater than the number of the IPv4 addresses. Every single domain has its web hosting server IP address as a record and in essence, this record tells the domain name where the website for it is. Depending on the system the provider uses, the record will 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 such a redirection to forward a domain address to a server that uses an IPv6 address, you will need to create an AAAA record for it.
