An AAAA record is an IP address in the freshly presented IPv6 format and it is made up of eight different sets of hexadecimal digits, unlike the IPv4 IPs, that include four groups of numbers between 1 and 255. An illustration of an IPv6 address would be 3014:0d43:23a3:2354:1320:8f3b:2635:3254 and with this format the amount of IPs which can be created is many times higher than the number of the IPv4 addresses. Every domain name has its web 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 the company uses, the record will be called A (IPv4) or AAAA (IPv6). Changing this record will allow you to host your Internet site with one company and your emails with a different one, so if you choose to use this kind of redirection to point a domain address to a server that uses an IPv6 address, you will have to create an AAAA record for it.
