An AAAA record is an IP in the freshly released IPv6 format and it is comprised of 8 different groups of hexadecimal numbers, as opposed to the IPv4 IPs, which include four groups of numbers between 1 and 255. An illustration of an IPv6 address is 3014:0d43:23a3:2354:1320:8f3b:2635:3254 and in this format the total number of IPs that may be created is many times bigger than the number of the IPv4 addresses. Every domain name has its web hosting server IP as a record and in essence, this unique record instructs the domain name where the site for it can be found. Depending on the system the company employs, the record will be called A (IPv4) or AAAA (IPv6). Changing this record permits you to host your Internet site with one provider and your e-mails 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'll need to set up an AAAA record for it.
