An AAAA record is an IP within the newly released IPv6 format and it consists of eight sets of hexadecimal digits, unlike the IPv4 IPs, which feature 4 sets of numbers 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 which can be created is many times larger than the number of the IPv4 addresses. Each and every domain name has its hosting server IP address as a record and in essence, this unique record tells the domain address where the Internet site for it is. Depending on the system which the service provider 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 decide to use such a redirection to forward a domain address to a server that uses an IPv6 address, you will have to create an AAAA record for it.
