An AAAA record is an IP address within the freshly presented IPv6 format and it is made up of 8 different groups of hexadecimal digits, as opposed to the IPv4 IPs, which feature four sets of digits 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 number of IPs that may be created is many times bigger than the number of the IPv4 addresses. Every domain has its website hosting server IP address as a record and in essence, this record informs the domain name where the website for it is located. Depending on the system that the company employs, the record will be called A (IPv4) or AAAA (IPv6). Changing this record permits you to host your website with one company and your emails 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 have to set up an AAAA record for it.
