Hey @Jan_Prummel,
I am sorry that Roon’s Security Alerts are adding up 
When it comes to the IP geolocation (just like @Geoff_Coupe mentioned 
), it is hardly accurate. It depends on your Internet Service provider.
I ran into an article that explains a little more how common this is (article is found here).
IP based geolocation services can only provide an approximate measure of geolocation accuracy. With these services, you can obtain:
- 95 percent to 99 percent accuracy of a user’s country.
- 55 percent to 80 percent accuracy for a user’s region or state
- 50 percent to 75 percent accuracy for a user’s city.
In practice, the actual accuracy may vary from provider to provider and depending on the location of the device. For instance, IP based geolocation services typically work better in big cities and work less well in smaller ones.
