An AAAA record is an Internet protocol address in the freshly presented IPv6 format and it is comprised of eight sets of hexadecimal digits, unlike the IPv4 IPs, which feature four sets of digits 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 sheer number of IPs that may be created is many times higher than the number of the IPv4 addresses. Each and every domain name has its hosting server IP address as a record and in essence, this unique record tells the domain 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 enables you to host your website with one company and your e-mails with a different one, so if you decide to use such a redirection to point a domain to a server that uses an IPv6 address, you will need to create an AAAA record for it.
