IPvFoo
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.

Does not work with proxy.
this thing is a must have for troubleshooting connection issue, helped me more than I can count, I love it.
Works as advertised and accurately with no hiccups. Even reveals to me that Google search prefetches the URLs
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?
It works!
Unique tool for a niche group of nerds such as myself, but excellent.
A must have to make sure that you're using IPv6, and that your websites are IPv6-enabled. Works very well and even shows active WebSockets, and requests to hosts.
Been using this for years, and works perfectly!
I found out about this on a post on Reddit IPv6 Forum. https://www.reddit.com/r/ipv6/comments/18im1xq/ipv4_vs_ipv6_ip_address_change/ I love it!!!!
This extension is a network pros dream extension. Thank you!

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.

It's an awesome extension. There is however an issue with the new Chrome 69 where after a while the icon reverts back to the default IPvFoo image instead of showing 4 or 6 and you need to reload the website to get it to show properly.

非常有用的扩展，实时查看当前网页连接的网站，使用的IP
这个看到的ip才是真的,有些用dns查的不是实际访问的ip,国内用户福利
I'm not a developer, just someone interested in seeing IPv6 penetration. IPvFoo is great for seeing not just the main page but the components are or are not using IPv6. (Bad news: as of this writing, almost every site I use is either IPv4-only or has an IPv4-only component, and that's even after filtering out most advertisements via AdBlock Plus.)
Good.
Good.
One of the few extension that report the ip of the site during the connection and not a resolution made by someone else.

As a network engineer, I find this very helpful for seeing what IP version various sites are using.
