About the connection test

What is tested?

After you start the connection test, we will check if your currently used internet connection offers support for the modern Internet Standards below.

  • IPv6: are websites with modern internet addresses reachable for you?
  • DNSSEC: are domain signatures validated for you?

Test report?

After the test is finished, you are directed to a test report. The report contains an overall percentage score and results per test section and per subtest. For more information see "Explanation of test report".

How to improve?

You can use this test report to improve your internet connection. Usually contacting your internet provider on this will be the best next step. In the communication with your internet provider you can use the permalink (i.e. the URL) of the test report.
