About DNS & DPI Diagnostics

Extension for diagnosing website availability and network restrictions. It helps users determine: — whether a website is accessible from the browser; — whether DNS and DNS-over-HTTPS (DoH) are working correctly; — whether there are possible signs of network-level blocking (DPI). The extension does not modify system or browser DNS settings and does not interfere with the user's network traffic. All checks are performed only when requested by the user. It is intended for analyzing website access issues and assisting with network troubleshooting.
