An AAAA record is an IP address in the recently presented IPv6 format and it is comprised of eight sets of hexadecimal numbers, as opposed to the IPv4 IPs, that include four groups of numbers in between 1 and 255. An illustration of an IPv6 address is 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. Every single domain name has its hosting server IP address as a record and in essence, this record instructs the domain name where the Internet site for it can be found. Depending on the system which the provider employs, the record will be called A (IPv4) or AAAA (IPv6). Changing this record allows you to host your Internet site with one company and your emails with a different one, so if you decide to use this type of redirection to forward a domain name to a server that uses an IPv6 address, you will need to create an AAAA record for it.
