What is IPvFoo?
"IPvFoo" is a Chrome extension designed to raise awareness about the global transition from IPv4 to IPv6. The extension operates real-time, displaying the server's IP address and providing a concise summary of IPv4, IPv6, and HTTPS information across all elements of the page.

Summary

I made this extension to raise everyday awareness of the global IPv4 to IPv6 transition. To respect your privacy, it keeps data in RAM and treats the network as read-only. I can maintain this without ads because there are no server costs.

IPvFoo's action icon shows a large red 4 or green 6 to indicate whether the outer page was fetched using IPv4 or IPv6. If the page connects to other domains, a smaller 4 or 6 appears alongside.

When you click the icon, a table appears with a row for each domain:

  • A padlock icon for http://, https://, or a mix of both.

  • The IPv4 or IPv6 address. If connections span more than one address, the most recent one wins. The address is highlighted in yellow while connections are open.

  • "⭮" for cached requests. The IP address may be stale if no connection was made.

  • "S" for WebSocket handshakes. The connection may still be active even if the address is not highlighted.

  • "W" if data was fetched through a Service Worker. These requests are linked to an origin (e.g. https://example.com/) instead of a tabId, so the same request may appear in multiple tabs.

Easy way to view all the domains used by a whitelisted website so you can add those domains to the whitelist too so the website will work correctly on a parent-filtered system.
