DNS leak test

See which DNS servers answer your device’s requests with a simple test powered by bash.ws.

• Run a DNS leak test with one button.
• View your public IP, detected DNS resolvers, available location details, and network providers.
• Read conclusions and explanations returned by bash.ws.
• Enable continuous testing while the app is active.
• Review saved test history. Consecutive identical results are grouped with timestamps and repeat counts.
• Inspect and copy diagnostics for the latest test.
• Use light or dark appearance, following your system or your own preference.

Designed for iPhone and iPad. Available in English, Polish, German, French, Simplified Chinese, and Russian.

Connect your VPN before testing if you want to check its DNS behavior. This app tests the DNS path used by the app; it does not change DNS settings or provide a VPN. Results in other apps may differ and are not a guarantee of device-wide protection. Continuous testing stops when you leave the app or lock the device.

Testing sends your public IP and DNS resolver observations to bash.ws. History is stored on your device and can be cleared in Settings. Server-side data handling is described at https://bash.ws/privacy.
