Last year, Google and other leading Internet sites and companies turned on dual-stack IP4/6 for their domains. Back then, it was only for one day. Yesterday, 6 June, it's on for good. And it works!

To test your connection, try http://test-ipv6.com.

Below are some ping6 tests from today, just for the record. nine.ch is my hosting provider.
