An AAAA record is an IP address within the freshly launched IPv6 format and it comprises of eight different sets of hexadecimal digits, as opposed to the IPv4 IPs, that include four sets of digits 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 can be created is many times greater than the number of the IPv4 addresses. Every domain has its web hosting server IP as a record and in essence, this record tells the domain address where the Internet site for it can be found. Depending on the system that the service provider uses, the record is going to 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 decide to use this type of redirection to forward a domain to a server that uses an IPv6 address, you'll need to create an AAAA record for it.
