An AAAA record is an IP within the freshly released IPv6 format and it is made up of eight groups of hexadecimal numbers, in contrast to the IPv4 IPs, which include four groups of digits in between 1 and 255. An illustration of an IPv6 address is 3014:0d43:23a3:2354:1320:8f3b:2635:3254 and with this format the sheer number of IPs which can be created is many times higher than the number of the IPv4 addresses. Every domain name has its web hosting server Internet protocol as a record and in essence, this unique record informs the domain name where the site for it can be found. Depending on the system which the company uses, the record will be called A (IPv4) or AAAA (IPv6). Changing this record will allow you to host your website with one company and your e-mails with another, so if you choose to use this type of redirection to forward a domain name to a server that uses an IPv6 address, you'll have to set up an AAAA record for it.
