Matomo and Geolocation, getting the location wrong from my Linux-machine

Hello,
Did install the ‘db-ip free database’.
After that installation, I can see that my linux/ubuntu machine (English browser) now has a Swedish-origin and not a US-origin.
Some machines, getting the wrong location - I can see that my colleague surfed in to the service this morning from his linux/Fedora machine … he is located here in Sweden but his location is USA ( he surfed in from his workplace, IP-address 172.16.0.0)

Best, i
