The Hall of Fame is a list of all domains that score 5 stars on
this website. Qualifying domains are added to the Hall
automatically, and then re-tested frequently.
The following X domains are IPv6 ready:
The outcome of the domain test is based solely on DNS and is
therefore susceptible to caching.

Your connection does support IPv6, but the embedded MAC-address uniquely
identifies your computer and its network interface, even if you connect to
another network. Consider enabling privacy extensions!
When a domain does have IPv6 nameservers, but the IPv6-only test fails, it's
usually either because the IPv6 nameservers aren't actually reachable, or
because the glue
records are missing. In other words, the IPv6 addresses for the nameservers
are not yet registered with the domain registry. Contact your domain name
registrar for instructions.
This website (or webapp, as some call it) was built to help raise awareness
about common configuration mistakes, and IPv6 in general. It caters to
customers who want to find out if their ISP is doing a good job, and to
network and system administrators who need reliable information to resolve
The frontend was made with HTML5 and jQuery. It fetches JSON data from a PLP backend that is based on Perl, FastCGI, and lighttpd. The backend exists to
provide a controlled environment for the DNS queries.
This website is meant purely as a testing tool; for information about IPv6,
please refer to your favorite search engine.
IPv6 is version 6 of the new Internet Protocol. Every networked device and every
internet application will need to support this. For now, most of the internet
is dual stacked: version 4 and 6 are used side-by-side and websites and other
internet services that are not yet IPv6 ready continue to function properly for the vast majority of users.
But the IPv4 address space is exhausted. They're all gone. Already many internet
users are connected through all kinds of tricks and workarounds. That works, but
it doesn't scale very well, in terms of bandwidth and the number of connected
devices. It is important that every web site starts accepting connections via
The protocol specification for IPv6 dates back to December 1998, but most
organisations have waited until the IPv4 pool was fully depleted. And now we
June 6th of 2012 is world wide "IPv6 Launch Day". Many large international
organizations will enable IPv6 during this day. But there is no technical
reason to wait for others. Why wait? Get IPv6 ready NOW!
