An AAAA record is an IP address within the recently introduced IPv6 format and it is made up of 8 different sets of hexadecimal numbers, unlike the IPv4 IPs, that include four groups of digits in 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 may be created is many times larger than the number of the IPv4 addresses. Every domain name has its website hosting server Internet protocol address as a record and in essence, this unique record instructs the domain where the site for it is located. Depending on the system the service provider uses, the record is going to be called A (IPv4) or AAAA (IPv6). Changing this record permits you to host your site with one company and your emails with a different one, so if you choose to use this type of redirection to point a domain address to a server that uses an IPv6 address, you will need to set up an AAAA record for it.
