An AAAA record is an IP address within the freshly presented IPv6 format and it comprises of eight different groups of hexadecimal numbers, unlike the IPv4 IPs, which include four 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 may be created is many times greater than the number of the IPv4 addresses. Every single domain has its hosting server Internet protocol address as a record and in essence, this record instructs the domain where the Internet site for it can be found. Depending on the system that the provider employs, the record will be called A (IPv4) or AAAA (IPv6). Changing this record will allow you to host your website with one company and your emails with another, so if you choose to use such a redirection to forward a domain to a server that uses an IPv6 address, you'll need to create an AAAA record for it.
