An AAAA record is an Internet protocol address in the newly launched IPv6 format and it is made up of eight different groups of hexadecimal numbers, as opposed to the IPv4 IPs, that include four groups of digits 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 can be created is many times higher than the number of the IPv4 addresses. Each domain has its web hosting server IP address as a record and in essence, that record instructs the domain where the website for it can be found. Depending on the system that the provider employs, the record is going to be called A (IPv4) or AAAA (IPv6). Changing this record allows you to host your site with one provider and your email messages with another, so if you choose to use such a redirection to forward a domain address to a server that uses an IPv6 address, you will have to set up an AAAA record for it.
