An AAAA record is an Internet protocol address in the newly introduced IPv6 format and it comprises of 8 sets of hexadecimal digits, in contrast to the IPv4 IPs, that include four groups of digits in between 1 and 255. An example of an IPv6 address would be 3014:0d43:23a3:2354:1320:8f3b:2635:3254 and with this format the amount of IPs that can be created is many times higher than the number of the IPv4 addresses. Each domain has its hosting server IP address as a record and in essence, that record informs the domain address where the Internet site for it is. Depending on the system that the service provider employs, the record is going to be called A (IPv4) or AAAA (IPv6). Changing this record will allow you to host your Internet site with one company and your e-mails with another, so if you decide to use such a 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.
