An AAAA record is an Internet protocol address within the freshly launched IPv6 format and it is comprised of eight different sets of hexadecimal digits, unlike the IPv4 IPs, which feature four sets of numbers between 1 and 255. A good example of an IPv6 address is 3014:0d43:23a3:2354:1320:8f3b:2635:3254 and with this format the total number of IPs that can be created is many times larger than the number of the IPv4 addresses. Each and every domain name has its website hosting server Internet protocol address as a record and in essence, this unique record informs the domain address where the site for it is. Depending on the system 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 a different one, so if you choose to use this kind of redirection to forward a domain name to a server that uses an IPv6 address, you will need to set up an AAAA record for it.
