Starting sometime today, after months of using NordVPN, it quit working. Discussions with their support identified that IPV6 was enabled on my PC. I disabled it on all adapters thinking problem solved but it was almost immediately re-enabled by some unknown process or program. I set the DisabledComponents registry setting documented here and elsewhere to FF but no matter what I do, IPV6 gets re-enabled on all my adapters. Any thoughts about what to try next or what might be turning IPV6 back on?
I have provided root instructions during boot to totally and summarily blow IPV6 away. IPV6 couldn't start no matter if any app or program attempts to make it happen. I am on linux, and I am guessing you are not. If you are then chime back in here and I/we can give you a step by step to eliminate any IPV6 concerns. For Windows I'll let someone else add their "magic". Its not tough but I don't code M$ anymore.
After performing this registry mod, did you reboot? If your on Win 10 and have fast startup enabled, you have to do a manual system restart for the setting to take effect. Also, did you create the reg. key correctly? This is the key, HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip6\Parameters\DisabledComponents and its a REG_DWORD type. After restarting your PC, open a command prompt and type less the quote marks, "ipconfig /all". You should see no evidence of any IPv6 components installed.
Try to apply this: Code: netsh int ipv6 isatap set state disabled netsh int teredo set state disabled netsh interface ipv6 6to4 set state state=disabled undoonstop=disabled reg add "HKLM\System\CurrentControlSet\Services\Tcpip6\Parameters" /v "DisabledComponents" /t REG_DWORD /d "255" /f
