An AAAA record is an Internet protocol address within the recently presented IPv6 format and it consists of 8 different sets of hexadecimal numbers, in contrast to the IPv4 IPs, that include four sets of digits 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 number of IPs that can be created is many times greater than the number of the IPv4 addresses. Every domain name has its website hosting server Internet protocol as a record and in essence, that record instructs the domain name where the Internet site for it can be found. Depending on the system which the company uses, the record will be called A (IPv4) or AAAA (IPv6). Changing this record will allow you to host your Internet site with one company and your email messages with a different one, 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 need to set up an AAAA record for it.
