Maybe try using Simple DNSCrypt if your using DNS Crypt 0.0.6. Use both resolvers also. I don't know if this will fix the leak but it will be more secure than 0.0.6. And you a lot of ways to customize it to your satisfaction.
Yes I am using the latest SimpleDNSCrypt. I always use the absolute latest software that is available.
Some ways to solve your DNS leak for Windows 10: Create a firewall rule to block all DNS traffic on port 53 and only allow access to your preferred DNS servers when connected via AirVPN (private). Check your network adapter settings and make sure DNS addresses list the correct addresses for DNSCrypt. If you're using a daemon then it usually points to localhost. Post the leaked DNS details here for further help. For all I know you might have a PAC rewriting rules or the horrible Windows registry bug that requires uninstalling your NIC device to clear the incorrect keys. Maybe a router intercepting DNS queries or a proxy. Could be an alien in your machine like Cortana or your organisation's group policy. Need more info: why do you think there's a DNS leak? What are you using to test? Did you restart your machine or clear cache yet? Have you checked running services like Windows DNS Cache and flushed it? Et cetera
I am using Windows 10 Enterprise x64
I am using this at home, no organization involved.
I have not tried windows firewall.
My network adapter settings are exactly what they should be.
IPv6 is entirely disabled on my system.
I am not aware of a windows registry bug that requires me to uninstall my NIC's to clear any incorrect keys.
I am using Enterprise version stripped down so I have no Cortana or any such nonsense. (Note: Using the version that I use or mentioning it being "stripped down" is not my issue, I have had openvpn running on this system without any dns leaks... It just randomly started leaking.)
I know there is a dns leak because every time I connect to openvpn I check my connection on ipleak.net.
Yes I have cleared my DNS cache many times.
Any ideas? Any help is appreciated.
