An AAAA record is an IP within the newly presented IPv6 format and it is made up of 8 sets of hexadecimal digits, in contrast to the IPv4 IPs, which feature four groups of numbers between 1 and 255. A good example of an IPv6 address would be 3014:0d43:23a3:2354:1320:8f3b:2635:3254 and in this format the amount of IPs that can 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 instructs the domain where the site for it is located. Depending on the system which the provider employs, the record is going to be called A (IPv4) or AAAA (IPv6). Changing this record allows you to host your website with one company and your emails with another, so if you decide to use this sort of 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.
