An AAAA record is an IP in the recently presented IPv6 format and it consists of 8 groups of hexadecimal numbers, unlike the IPv4 IPs, which include 4 sets of digits in between 1 and 255. An example of an IPv6 address would be 3014:0d43:23a3:2354:1320:8f3b:2635:3254 and with this format the amount of IPs that can be created is many times bigger than the number of the IPv4 addresses. Each domain has its website hosting server IP as a record and in essence, this unique record informs the domain where the website for it is located. Depending on the system that the company employs, the record is going to be called A (IPv4) or AAAA (IPv6). Changing this record enables you to host your Internet site with one provider and your email messages with another, so if you decide to use this kind of redirection to point a domain to a server that uses an IPv6 address, you'll need to set up an AAAA record for it.
