DNS Integrity Checker wot bruno

DNS Integrity Checker is a security-focused browser extension that helps detect potential DNS manipulation or hijacking.

When you visit a website, the extension compares the resolved IP address used by your browser with results from trusted public DNS resolvers such as Cloudflare (1.1.1.1) and Google (8.8.8.8).

Key features:

• Detects mismatches between local DNS resolution and trusted resolvers
• Identifies suspicious cases such as private or loopback IP addresses
• Provides real-time visual feedback through the browser toolbar
• Displays detailed information about domain resolution in a popup
• Sends alerts when critical inconsistencies are detected

The extension is designed to help identify:

• DNS hijacking attempts
• Misconfigured or malicious DNS resolvers
• Local overrides (e.g. hosts file manipulation)
• Unexpected IP resolution behavior

Privacy:

This extension does not collect, store, or transmit any personal or browsing data.
All analysis is performed locally in the browser.
The only external requests made are DNS queries to trusted public resolvers (Cloudflare and Google) for verification purposes.

This tool is intended for security enthusiasts, system administrators, and anyone interested in improving their visibility into DNS behavior.
