An AAAA record is an IP address in the newly released IPv6 format and it comprises of eight different sets of hexadecimal numbers, in contrast to the IPv4 IPs, which include 4 sets of digits in between 1 and 255. A good example of an IPv6 address would be 3014:0d43:23a3:2354:1320:8f3b:2635:3254 and with this format the number of IPs that may be created is many times larger than the number of the IPv4 addresses. Every domain has its website hosting server IP address as a record and in essence, this unique record tells the domain name where the website for it can be found. Depending on the system which the provider employs, the record is going to be called A (IPv4) or AAAA (IPv6). Changing this record enables you to host your site with one provider and your email messages with a different one, so if you choose to use such a redirection to forward a domain name to a server that uses an IPv6 address, you will have to set up an AAAA record for it.
