An AAAA record is an IP within the newly introduced IPv6 format and it consists of 8 different groups of hexadecimal digits, in contrast to the IPv4 IPs, which feature 4 groups of numbers in between 1 and 255. A good example of an IPv6 address would be 3014:0d43:23a3:2354:1320:8f3b:2635:3254 and with 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 hosting server Internet protocol as a record and in essence, that record informs the domain where the Internet site for it is. Depending on the system which the service provider employs, the record will be called A (IPv4) or AAAA (IPv6). Changing this record allows you to host your website with one provider and your emails with another, so if you choose to use such a 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.
