An AAAA record is an IP in the newly presented IPv6 format and it is made up of 8 different groups of hexadecimal numbers, in contrast to the IPv4 IPs, that include 4 sets of digits in between 1 and 255. A good example of an IPv6 address would be 3014:0d43:23a3:2354:1320:8f3b:2635:3254 and with this format the total number of IPs that could be created is many times bigger than the number of the IPv4 addresses. Every single domain has its web hosting server IP as a record and in essence, that record informs the domain name where the site for it is. Depending on the system which the company uses, the record will be called A (IPv4) or AAAA (IPv6). Changing this record enables you to host your site with one company and your email messages with another, so if you choose to use this type of redirection to point a domain address to a server that uses an IPv6 address, you will need to set up an AAAA record for it.
