To participate, you will need a personal computer running MS Windows and you will need IPv6 Internet access.
For example, a Windows laptop tethered (connected via Wi-Fi) to a smartphone will likely work. To verify that your Windows computer has IPv6 connectivity, open a command prompt and run "ipconfig /all". Look for a line that begins with exactly just "IPv6 Address". For example, ignore any line that begins with "Link-local IPv6 Address"; that doesn't count!
