An AAAA record is an IP address in the recently released IPv6 format and it comprises of eight groups of hexadecimal numbers, as opposed to the IPv4 IPs, which feature 4 sets of digits between 1 and 255. An illustration of an IPv6 address would be 3014:0d43:23a3:2354:1320:8f3b:2635:3254 and with this format the sheer number of IPs that can be created is many times higher than the number of the IPv4 addresses. Every domain has its web hosting server IP address as a record and in essence, this unique record instructs the domain where the website for it can be found. Depending on the system that the service provider uses, the record is going to be called A (IPv4) or AAAA (IPv6). Changing this record permits you to host your Internet site with one provider and your e-mails with a different one, so if you decide to use this sort of redirection to point a domain address to a server that uses an IPv6 address, you'll need to set up an AAAA record for it.
