An AAAA record is an IP within the newly launched IPv6 format and it is made up of 8 different sets of hexadecimal numbers, unlike the IPv4 IPs, which feature four sets of numbers in 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 can be created is many times greater than the number of the IPv4 addresses. Every single domain name has its website hosting server IP address as a record and in essence, that record informs the domain address where the site for it is. Depending on the system the provider employs, the record is going to be called A (IPv4) or AAAA (IPv6). Changing this record enables you to host your website with one provider and your e-mails with a different one, so if you decide to use this kind of redirection to forward a domain to a server that uses an IPv6 address, you will need to create an AAAA record for it.
