An AAAA-record is used to specify the IPv6 address for a host.
IPv6 is the future replacement for the current IP address system (also known as IPv4).
The current IPv4 addresses are 32 bits long ( x . x . x . x = 4 bytes), and therefore "only" support a total of 4,294,967,296 addresses - less than the global population.
With this limitation there is an increasing shortage of IPv4 addresses.
To solve the problem, the whole Internet will eventually have to be migrated to IPv6.
IPv6 addresses are 128 bits long and are written in hexadecimal numbers separated by colons (:) at every four digits.
Zeros can be skipped - for example: 4C2F::1:2:3:4:567:89AB.
Few applications and network devices currently support IPv6 and IPv6 addresses are not yet generally available, but this is expected to change rapidly.
To create a new AAAA-record, right-click a zone in the left list in the DNS Records window, and select "Other new record" from the pop-up menu.
