Windows by default uses IPv6 "Privacy Extensions" (defined in RFC 4941), which is not supported on Binary Lane.
When they are enabled, instead of using the auto-configured address that can be seen in mPanel, Windows will create its own address essentially at random. This random address will not work, which can result in sporadic or permanent problems when using IPv6.
You can correct this issue by disabling the privacy extensions. To do so:
- Open a Command Prompt as Administrator - on Windows 2012, you can do this by right-clicking the Start button, and choosing "Command Prompt (Administrator)"
- Paste in the following commands:
netsh interface ipv6 set global randomizeidentifiers=disabled store=active
netsh interface ipv6 set global randomizeidentifiers=disabled store=persistent
netsh interface ipv6 set privacy state=disabled store=active
netsh interface ipv6 set privacy state=disabled store=persistent
After each command, you should see an "Ok." response.
Once these four commands are executed, within a few seconds Windows will switch to the correct auto-configured IPv6 address.
