Extension summary

Analyze keywords

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.

Risk impact

IPvFoo is risky to use as it requires a number of sensitive permissions that can potentially harm your browser and steal your data. Exercise caution when installing this extension. Review carefully before installing. We recommend that you only install IPvFoo if you trust the publisher.
