No-IP now supports the creation and setup of IPv6 (AAAA) records via the web interface. This is a feature available to our Plus Managed DNS users that have already received IPv6 records from their ISP or bandwidth provider. Please note that IPv6 is not yet supported by our software update clients.
IPv6 is the internet protocol version 6 that is set to replace the current version 4 sometime in the next upcoming years. IPv6 was introduced in 1998 and as of 2008 is being used by about 1% of the internet addressable devices in the world.
For more information on IPv6 records please take a look at this article.
