An AAAA record is an IP address within the newly presented IPv6 format and it is comprised of eight groups of hexadecimal numbers, in contrast to the IPv4 IPs, which feature four groups of digits between 1 and 255. An illustration of an IPv6 address would be 3014:0d43:23a3:2354:1320:8f3b:2635:3254 and in this format the total number of IPs that could be created is many times bigger than the number of the IPv4 addresses. Every domain has its website hosting server IP as a record and in essence, this record instructs the domain where the site for it is located. Depending on the system which the provider employs, the record is going to be called A (IPv4) or AAAA (IPv6). Changing this record permits 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 point a domain name to a server that uses an IPv6 address, you will need to set up an AAAA record for it.
