An AAAA record is an Internet protocol address in the recently introduced IPv6 format and it comprises of eight different groups of hexadecimal numbers, in contrast to the IPv4 IPs, that include 4 groups of numbers in between 1 and 255. A good example of an IPv6 address is 3014:0d43:23a3:2354:1320:8f3b:2635:3254 and with this format the sheer number of IPs which can be created is many times higher than the number of the IPv4 addresses. Each and every domain has its hosting server Internet protocol as a record and in essence, this unique record informs the domain address where the Internet site for it can be found. Depending on the system the service provider uses, the record is going to be called A (IPv4) or AAAA (IPv6). Changing this record allows you to host your site with one provider and your e-mails with a different one, so if you choose to use this type of redirection to forward a domain name to a server that uses an IPv6 address, you will need to set up an AAAA record for it.
