This plugin links the IP of the visitor with a database of IP ranges to be able to recognize special visitors. The IP ranges can be imported from a json file, either via a command line command or using the scheduler to download it. For more infos check the docs and the FAQ. The minimum required PHP version is 7.4. Recommended is 8.0+. Starting with v3.0.0, PHP 7.3 is no longer supported.
At the moment it is not possible to remove ranges from the database without manual database changes. As a workaround you can uninstall the plugin (this deletes the tables) and install the plugin again.
