An AAAA record is an IP in the recently launched IPv6 format and it is made up of eight sets of hexadecimal numbers, as opposed to the IPv4 IPs, that include four sets of digits in between 1 and 255. An illustration 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 greater than the number of the IPv4 addresses. Every single domain has its website hosting server Internet protocol as a record and in essence, this unique record instructs the domain name where the Internet site for it is. Depending on the system that the company uses, the record will be called A (IPv4) or AAAA (IPv6). Changing this record will allow you to host your Internet site with one company and your emails with another, 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.
