I configured my routers DHCP to use Level 3 DNS which is 188.8.131.52 and 184.108.40.206 and it is also correctly shown when I check via
ipconfig dns output:
But when I check via DNSLeakTest (or any other leak tests) it always shows OpenDNS.
I made sure network adapter settings are set to automatic, I tried ipconfig /flushdns and more but still no luck. Also other computers and devices (android, ios) correctly show Level3 on DNSLeakTest. So what might be the cause and how to fix it?
