An AAAA record is an IP address within the recently released IPv6 format and it is made up of 8 groups of hexadecimal numbers, unlike the IPv4 IPs, which feature four sets of numbers 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 total number of IPs which can be created is many times bigger than the number of the IPv4 addresses. Each and every domain name has its web hosting server IP as a record and in essence, that record instructs the domain name where the website for it is. Depending on the system the company uses, the record will be called A (IPv4) or AAAA (IPv6). Changing this record will allow you to host your Internet site with one provider and your emails 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 need to set up an AAAA record for it.
