Overview
Product summary
Review the store description, core capabilities, and common use cases.
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.

Trabalho com firewall e é muito útil pra identificar dns utilizados em uma página, como apis externas... Ajuda muito nas liberações de inspeção ssl
not working. Can't see any icon in address bar
It brings great convenience to my debugging work

I love this ext but there is a unexpecting behaviour happened, when i accesed to a web Ipvfoo gives me more results in one OS (xp old chrome) than in Win7 (new chrome). In XP when I go to larazon_es show me 39 results but same web in win7 shows just 31 and in win7 virtualmachine even a lot less. Why that happend??
I love this browser extension however the only issue I see is that recently it has stopped working on Chrome Dev on MacOS Catalina -- every website shows the generic white "IPvFoo" icon instead of the "6" or "4". Extension works great with Chrome Dev on windows 10 so i'm not sure what has changed.
This is an amazingly useful extension for those of us trying to get up on IPv6. I brought up a HE.net tunnel for this LAN, and got IPs assigned to all the local devices. I didn't see a really good way to see which sites are IPv6, and the extent of their use. I'm impressed seeing how many organizations are up now. Not too long ago, it was rare at best. My ISP still doesn't support IPv6, but the HE tunnel lets me. The connection chart is nice, so I can see the extent of the site's implementation.
Ferramenta vem se transformando em indispensável para quem trabalham com infraestrutura de TICs.
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.
