IPvFoo - Chrome Extension for Monitoring IP Address

"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. Suited for privacy-conscious users, IPvFoo retains data in RAM and operates under a read-only mode in the network, ensuring user data security at all times.

Extension summary

IPvFoo adds an icon to the toolbar, showing 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 hostname. See the icon tooltips for more information. Clicking on a hostname or address will select it for convenient copying. There is also a right-click option to look up addresses on bgp.he.net.

IPvFoo is Free Software (Apache 2.0 license). I made this 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.

I have a question: what does it mean if the main address field simply says "(no address)" but the site comes up and displays fine?
