An AAAA record is an IP within the newly launched IPv6 format and it is made up of 8 different sets of hexadecimal numbers, in contrast to the IPv4 IPs, which include 4 sets of numbers 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 amount of IPs that could be created is many times larger than the number of the IPv4 addresses. Each and every domain has its hosting server IP address as a record and in essence, that record instructs the domain name where the Internet site for it is. Depending on the system the company employs, the record is going to be called A (IPv4) or AAAA (IPv6). Changing this record allows you to host your site with one company and your e-mails with another, so if you decide to use this type of 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.
