An AAAA record is an Internet protocol address within the freshly introduced IPv6 format and it is made up of eight sets of hexadecimal digits, as opposed to the IPv4 IPs, which feature 4 sets of numbers 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 could be created is many times bigger than the number of the IPv4 addresses. Every single domain has its hosting server IP as a record and in essence, this unique record informs the domain name where the Internet site for it is located. Depending on the system which the company uses, the record is going to be called A (IPv4) or AAAA (IPv6). Changing this record permits you to host your site with one provider and your email messages with another, so if you choose to use this type of redirection to point a domain name to a server that uses an IPv6 address, you'll have to set up an AAAA record for it.
