An AAAA record is an Internet protocol address within the freshly released IPv6 format and it comprises of 8 sets of hexadecimal numbers, unlike the IPv4 IPs, which feature 4 sets of digits in between 1 and 255. An illustration of an IPv6 address would be 3014:0d43:23a3:2354:1320:8f3b:2635:3254 and in this format the amount of IPs that may be created is many times larger than the number of the IPv4 addresses. Every domain has its web hosting server IP address as a record and in essence, this record informs the domain 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 enables you to host your website with one company and your e-mails with a different one, so if you choose to use this sort of redirection to point a domain address to a server that uses an IPv6 address, you'll have to create an AAAA record for it.
