## Description

IPvFoo is a privacy-focused Chrome extension designed to raise awareness about the global transition from IPv4 to IPv6. It displays the server IP address alongside HTTPS status in real-time across all page elements without storing data beyond RAM, ensuring user privacy.

The extension icon indicates the protocol used for page fetch with a clear red "4" for IPv4 or green "6" for IPv6. Additional smaller icons display alongside for other connected domains. Clicking the icon reveals a detailed table listing each domain's HTTPS status, IPv4 or IPv6 address, and connection types, with helpful symbols for cached, WebSocket, and Service Worker requests. Users can easily copy or look up IP addresses externally. IPvFoo is free, open-source software licensed under Apache 2.0 and operates entirely ad-free with no server costs.

## Review summary

Users appreciate IPvFoo for its clear IP display and usefulness in network debugging, highlighting its role in promoting IPv6 adoption. Being open source adds trust and flexibility. The main concern is the required broad permission to access data from all websites, a limitation imposed by browser permission scopes rather than the add-on itself.

### Pros

- Displays IP addresses clearly and accurately
- Helpful for debugging network issues
- Promotes IPv6 adoption
- Open source allowing manual building and installation
- Very practical and useful

### Cons

- Requires 'Access your data for all websites' permission due to browser limitations
- No narrowly-scoped permission available in browsers for this functionality
- Potential trust concerns due to broad permission scope
