An AAAA record is an Internet protocol address within the freshly introduced IPv6 format and it comprises of 8 different sets of hexadecimal numbers, as opposed to the IPv4 IPs, which include four groups of numbers 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 total number of IPs that can be created is many times larger than the number of the IPv4 addresses. Each domain name has its website hosting server Internet protocol address as a record and in essence, this unique record instructs the domain name where the website for it can be found. Depending on the system which the company employs, the record is going to be called A (IPv4) or AAAA (IPv6). Changing this record allows you to host your website with one company and your e-mails with a different one, so if you choose to use this type of redirection to point a domain name to a server that uses an IPv6 address, you will need to set up an AAAA record for it.
