MaxMind’s Organization and ISP databases can be used to get company/provider information for visitors.
To use them, simply select & purchase the database you want and upload it to the misc Piwik directory.
If you are using a GeoIP server module you may have to do more to get it to work w/ Piwik. The relevant instructions are here for Apache, and here for Nginx.
If you are using the PECL extension and are using a custom directory for your GeoIP databases, upload the new database to this directory instead of Piwik’s misc directory.
Thanks for contacting us! We will get in touch with you shortly.
