An AAAA record is an IP within the newly introduced IPv6 format and it consists of eight different sets of hexadecimal numbers, in contrast to the IPv4 IPs, which feature 4 groups of numbers in between 1 and 255. A good example of an IPv6 address is 3014:0d43:23a3:2354:1320:8f3b:2635:3254 and in this format the amount of IPs that may be created is many times higher than the number of the IPv4 addresses. Each and every domain has its website hosting server IP as a record and in essence, that record informs the domain where the site for it can be found. Depending on the system which the company employs, the record will be called A (IPv4) or AAAA (IPv6). Changing this record permits you to host your Internet site with one provider and your email messages with a different one, so if you decide to use this kind of redirection to forward a domain address to a server that uses an IPv6 address, you will need to set up an AAAA record for it.
