An AAAA record is an IP address in the recently presented IPv6 format and it is made up of 8 sets of hexadecimal numbers, unlike the IPv4 IPs, that include 4 sets of numbers between 1 and 255. An example of an IPv6 address is 3014:0d43:23a3:2354:1320:8f3b:2635:3254 and in 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 hosting server Internet protocol as a record and in essence, that record tells the domain where the Internet site for it can be found. Depending on the system the service provider uses, 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 sort of redirection to forward a domain to a server that uses an IPv6 address, you will have to set up an AAAA record for it.
