SixIndicator is a WebExtension Plugin which indicates via an icon, if you are viewing the website with IPv6 or IPv4. When clicking on the icon, more information is shown, like the number of requests per domain and if these requests were made via IPv6 or IPv4.

This plugin is heavily inspired by Ashley Baldocks SixOrNot plugin, which is not maintained anymore, since Firefox has switched to WebExtensions. It is completly written from scratch, but aims at looking similar than SixOrNot. Similar plugin are WhatIP or IPvFoo.

• Looking up other IP addresses for used domains. Showing only the Ip address, which was used
• Indicator, if website is IPv6-Only (due to above limitation)
