An AAAA record is an IP address in the freshly introduced IPv6 format and it is made up of eight different sets of hexadecimal digits, as opposed to the IPv4 IPs, which feature four groups 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 number of IPs that can be created is many times higher than the number of the IPv4 addresses. Each and every domain has its web hosting server Internet protocol address as a record and in essence, this record informs the domain where the website for it can be found. 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 site with one provider and your e-mails with another, so if you decide to use this type of redirection to point a domain to a server that uses an IPv6 address, you'll need to set up an AAAA record for it.
