An AAAA record is an IP in the freshly presented IPv6 format and it comprises of eight different sets of hexadecimal numbers, unlike the IPv4 IPs, which feature four groups 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 number of IPs that could be created is many times larger than the number of the IPv4 addresses. Each domain has its web hosting server IP address as a record and in essence, that record instructs the domain where the Internet site for it is. Depending on the system which the provider uses, the record is going to be called A (IPv4) or AAAA (IPv6). Changing this record allows you to host your website with one company and your email messages with a different one, so if you decide to use such a redirection to forward a domain address to a server that uses an IPv6 address, you will have to set up an AAAA record for it.
