An AAAA record is an IP within the newly launched IPv6 format and it comprises of 8 different sets of hexadecimal numbers, as opposed to the IPv4 IPs, which feature 4 groups of digits in between 1 and 255. An example of an IPv6 address would be 3014:0d43:23a3:2354:1320:8f3b:2635:3254 and in this format the number of IPs that may be created is many times greater than the number of the IPv4 addresses. Each domain has its website hosting server Internet protocol 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 the company employs, the record will be called A (IPv4) or AAAA (IPv6). Changing this record allows you to host your website with one company and your email messages with another, so if you decide to use this type of redirection to forward a domain name to a server that uses an IPv6 address, you'll have to create an AAAA record for it.
