An AAAA record is an Internet protocol address in the recently released IPv6 format and it is made up of 8 different groups of hexadecimal digits, unlike the IPv4 IPs, which feature four sets of numbers in between 1 and 255. An illustration of an IPv6 address is 3014:0d43:23a3:2354:1320:8f3b:2635:3254 and in this format the total number of IPs that could be created is many times larger than the number of the IPv4 addresses. Every single domain has its hosting server IP address as a record and in essence, this record informs the domain name where the website for it can be found. Depending on the system that the company employs, the record is going to be called A (IPv4) or AAAA (IPv6). Changing this record will allow you to host your Internet site with one provider and your e-mails with a different one, so if you decide to use this type of redirection to forward a domain name to a server that uses an IPv6 address, you will need to create an AAAA record for it.
