A useful DNS leak check records the expected resolver path before interpreting the result.
Establish a baseline
Record the device, network, DNS configuration, browser behavior, and resolver results without the VPN.
Test more than one state
Repeat checks while connected, reconnecting, switching networks, and recovering from sleep.
Store reproducible evidence
Attach dated results to the relevant provider review rather than turning one screenshot into a universal claim. The NordVPN testing draft shows where provider-specific observations should be recorded.
