An AAAA record is an IP within the recently launched IPv6 format and it consists of eight groups of hexadecimal digits, in contrast to the IPv4 IPs, which include 4 sets of digits in between 1 and 255. An example of an IPv6 address is 3014:0d43:23a3:2354:1320:8f3b:2635:3254 and with this format the number of IPs that could be created is many times greater than the number of the IPv4 addresses. Each and every domain name has its hosting server IP address as a record and in essence, this record informs the domain where the site for it is. Depending on the system the company uses, the record is going to be called A (IPv4) or AAAA (IPv6). Changing this record permits you to host your site with one company and your e-mails with another, so if you choose to use this kind of redirection to point a domain to a server that uses an IPv6 address, you will need to set up an AAAA record for it.
