An AAAA record is an IP in the freshly launched IPv6 format and it consists of eight different sets of hexadecimal numbers, in contrast to the IPv4 IPs, which include 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 with this format the sheer number of IPs that could be created is many times greater than the number of the IPv4 addresses. Each and every domain name has its hosting server IP as a record and in essence, this unique record instructs the domain where the site for it is. Depending on the system the service provider uses, the record will be called A (IPv4) or AAAA (IPv6). Changing this record will allow you to host your site with one company and your e-mails with another, so if you choose to use this sort of redirection to forward a domain to a server that uses an IPv6 address, you will need to create an AAAA record for it.
