With the forthcoming changes in Firefox 60 to support DNS lookup I've decided to update SixOrNot using the WebExtensions API. 3.0 does drop some functionality, some of which will be coming back (like copying addresses) and some probably won't (like local address display). New version soon for FF 60 beta to support DNS lookups :)
See at a glance whether websites support IPv6, with additional information about each domain contacted to display the current page. Now also shows local IP addresses, proxy use and TLS/security status for connections.
- Information comes from both the DNS entries of the servers contacted to load page elements and from the connections Firefox makes to those servers - providing the most complete information possible.
- The icon can be shown either in the address bar or as a toolbar button (which can be customized to many locations in the Firefox interface).
- This addon does not consult with any external service to determine your own IP address, avoiding any privacy concerns arising from such behaviour.
- By looking at both the DNS entries for a domain and the IP version used to make connections to it Sixornot can see when you are connecting via IPv4, but the remote site has the capability to be contacted via IPv6 - useful for those interested in whether sites are IPv6-capable but are not on an IPv6 connection themselves. (v.2)
- DNS and IP address information can be copied to the clipboard by clicking on entries. (v.2)
- Shows information about proxies used to load page resources</lI>
