An AAAA record is an IP address in the recently introduced IPv6 format and it is comprised of 8 different sets of hexadecimal numbers, in contrast to the IPv4 IPs, which feature four groups of digits between 1 and 255. A good example of an IPv6 address is 3014:0d43:23a3:2354:1320:8f3b:2635:3254 and in this format the number of IPs that could be created is many times larger than the number of the IPv4 addresses. Each and every domain name has its web hosting server IP as a record and in essence, this unique record tells the domain where the site for it is located. Depending on the system which the company uses, the record is going to be called A (IPv4) or AAAA (IPv6). Changing this record allows you to host your Internet site with one company and your email messages with another, so if you decide to use this sort of redirection to forward a domain name to a server that uses an IPv6 address, you'll have to create an AAAA record for it.
