IPvFoo Chrome 插件, crx 扩展下载

                    
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.
