Problem with country detection

Hello,
I have installed Piwik in my website, and when I was seeing the report i founded that Algerian IP’s are shown as French IP’s, help please !

See Troubleshooting - Analytics Platform - Matomo

Good news: GeoIP is now integrated in Piwik, enabling Accurate Visitors Geolocation in your Analytics reports. To enable GeoIP go to the Settings > Geolocation admin page, and follow the short instructions.

You can also get an even more accurate Country & City Database from here to enjoy top accuracy in detecting your visitors locations.
