LIVE DIAGNOSTIC
NOT TESTEDRun DNS Resolver Comparison
Runs identical DNS-over-HTTPS requests against independent public resolvers and shows whether returned answers differ.
Your test results will appear here. Nothing runs until you press the button.
Full tests run only after you start them. Public tools need no extension. An optional extension status check may run in Chrome. Results are not saved to your DI VPN account.
