An AAAA record is an IP address within the recently presented IPv6 format and it is made up of eight sets of hexadecimal digits, in contrast to the IPv4 IPs, that include four groups 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 in this format the total number of IPs that could be created is many times bigger than the number of the IPv4 addresses. Every single domain has its hosting server IP address as a record and in essence, this record tells the domain where the site for it is. Depending on the system the provider employs, the record will be called A (IPv4) or AAAA (IPv6). Changing this record permits you to host your Internet site with one company and your emails with another, so if you decide to use this sort of redirection to forward a domain address to a server that uses an IPv6 address, you will have to create an AAAA record for it.
