An AAAA record is an Internet protocol address in the recently introduced IPv6 format and it comprises of 8 groups of hexadecimal digits, unlike the IPv4 IPs, which feature 4 groups of digits between 1 and 255. A good example of an IPv6 address is 3014:0d43:23a3:2354:1320:8f3b:2635:3254 and in this format the number of IPs that could be created is many times larger than the number of the IPv4 addresses. Each and every domain name has its website hosting server Internet protocol as a record and in essence, this record informs the domain where the site for it can be found. Depending on the system the company employs, the record will be called A (IPv4) or AAAA (IPv6). Changing this record permits you to host your website with one provider and your email messages with another, so if you choose to use this type of redirection to point a domain to a server that uses an IPv6 address, you'll need to create an AAAA record for it.
