AAAA Records

A and AAAA records are equally important when it comes to resolving DNS. The difference lies in that A records is used to resolve a hostname which corresponds to an IPv4 address, while AAAA records are used to resolve a domain name which corresponds to an IPv6 address.
Clearly, because IPv4 is currently the most commonly used IP address, A records are also the most commonly used in comparison to AAAA records. Yet the potential for AAAA is growing because chances are that IPv6 will be the most commonly used internet protocol address system in the future.
