An AAAA record is an IP address within the freshly released IPv6 format and it consists of 8 different sets of hexadecimal numbers, unlike the IPv4 IPs, that include 4 groups of digits between 1 and 255. An example of an IPv6 address would be 3014:0d43:23a3:2354:1320:8f3b:2635:3254 and in this format the sheer number of IPs that may be created is many times higher than the number of the IPv4 addresses. Every domain has its hosting server IP address as a record and in essence, that record instructs the domain name where the site for it is located. Depending on the system that the service provider 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 email messages with another, so if you decide to use this sort of 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.
