Country Flags & IP Whois is a browser extension that displays the server's flag in the toolbar area indicating the current webserver's physical location. This is done by comparing the IP range with an offline database from MaxMind's GeoLite (there is no server interaction to get the location). Knowing the server location adds an extra layer of awareness to your browsing and can be useful to indicate the native languages and legal jurisdictions that may apply. Additional information about Geolocation or Whois info can be obtained via the click on the toolbar icon.

This is an open-source project:

Note that the CSV databases are compressed. For more info please visit the FAQs page and the source code.
