Display the server IP address, with a realtime summary of IPv4, IPv6, and HTTPS information across all page elements. 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.

Yet Another Flags
Shows country flag for the website near the location bar. ✨ If you want to see a precise location for a domain — country, city, state — displayed with a pixel-perfect country flag icon, try this one! 📝 Extension shows a country flag for the site opened in the current tab. 📍 Precision is achieved with Google's free DNS-over-HTTPS service. The backend that I run at 🔐 https://geoip.furman.im provides country, city, region, and post code data. 🙅♀️ Extension respects user's privacy. Neither it listens to user's network traffic, nor does it collect any data, nor does it track or identify users in any way, and never will. The same applies to the backend service. 🥬 GeoLite2 database created by MaxMind, available from maxmind.com, is updated twice a week – on Tuesdays and Fridays, so geographical data is always as fresh as MaxMind makes it. 🚩 Extension uses excellent "Flags of the World" icons by Mark James (of famfamfam.com fame). Flags are ISO 3166 compliant, so please let me know if some country has the wrong flag displayed. 🟢 April 20, 2023 🆕 Display resolution 🕙 timestamp in the IP address hint in the popup. Hover the mouse cursor over the IP address and wait for the hint to appear. 🟢 April 17, 2023 🆕 Display loading and error states in the page action icon — no more guessing if the data is loaded or resolution has failed — the icon provides visual feedback immediately. 🟢 February 3, 2023 🎉 Extension is back into active maintenance mode. 🇺🇦 Extension includes a link to Ukrainian non-profit SaveLife https://savelife.in.ua; they provide help with the war effort. The link is not featured prominently, so it's not distracting — see if you can find it!
