IPv6/IPv4 connectivity test system
This project is testing web users' IPv4 and IPv6 connectivity. The goals are to track the adoption of IPv6 and the number of users who have trouble connecting to servers with both A and AAAA records.
- What are the current statistics?
- See the global statistics page.
- How can I help?
- Create an account and install the small javascript widget on your site. The account page gives instructions.
- How does the system work?
- A bit of javascript inserts image tags for three 1x1 pixel gifs. The images are hosted on servers with IPv4 only, IPv6 and IPv6+IPv4 DNS records. The javascript sends the results back to the server.
- What information is tracked?
- The response time of each image request and the (external/public) IPs the user used to access the test server. We also store the 'http referer', the ID of the site, the time of the test. The javascript sets a 'v6uq' cookie in your domain for 28 days to prevent the test from running more than about once a month per user. The value of this cookie is also stored.
- What information is made public?
- The statistics from any one site are only used in aggregate for the global statistics unless the site owner enables "public statistics" for the site.
- Is the code for the system available?
- Yes, it is in git.
