"Country Flags & IP WHOIS" adds a toolbar/address bar button with an icon of current location of the website's server. This information is extracted from the IP address of the responding server. The extension has a built-in table to convert the provided IP address to the country flag. The extension has a lightweight database to convert an arbitrary IP address to ISO country code. For the extension to be lightweight as possible, the database is highly optimized and compressed. So there is no external resource involve during IP resolution. If additional information is required, click on the toolbar to direct you to the detail page. Available tools in the right-click menu (only 5 menu items are visible in the root menu):
