An AAAA record is an IP address within the freshly released IPv6 format and it is made up of eight different groups of hexadecimal digits, as opposed to the IPv4 IPs, which include 4 sets of numbers 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 could be created is many times bigger 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, that record tells the domain where the Internet site for it can be found. Depending on the system that the company employs, the record will be called A (IPv4) or AAAA (IPv6). Changing this record permits you to host your site with one company and your e-mails with a different one, so if you choose to use this kind of redirection to point a domain to a server that uses an IPv6 address, you will have to create an AAAA record for it.
