An AAAA record is an IP within the recently launched IPv6 format and it consists of eight sets of hexadecimal digits, unlike the IPv4 IPs, which include 4 groups of digits in between 1 and 255. A good example of an IPv6 address is 3014:0d43:23a3:2354:1320:8f3b:2635:3254 and in this format the sheer number of IPs that may be created is many times greater than the number of the IPv4 addresses. Each and every domain name has its hosting server Internet protocol as a record and in essence, this unique record instructs the domain address where the Internet site for it is. Depending on the system that the service provider employs, 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 a different one, so if you choose to use such a redirection to point a domain address to a server that uses an IPv6 address, you will have to set up an AAAA record for it.
