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.

Excellent development tool. Lets you easily see what IP you are using to access a website, as well as the IPs for all the other resources on the page.
馬上就可以看出來是透過IPv4連線還是IPv6，相當方便，需要更詳細資料也只要點一下即可
Works correctly if you have a direct connection to the Internet and shows whether you are connecting over v4 or v6 and shows the site's v4 or v6 address, but if you are behind a proxy it does not work (it shows the IP address of the proxy)
A great extension. It does just what I want.
Just what I needed
I initially picked this up to see/ensure that IPv6 connections were working correctly/even happening, but I continue to find it useful for monitoring v4 connections also.
Perfect! Very useful!
very useful tool! Thanks a lot for developing it!
finally one that works.
I'm working on converting our worldwide network to dual-stack, and I need to know at a glance when I'm getting to sites via IPv6 or IPv4. This extension is invaluable for testing, and also cool for IPv6 geeks.
