Actually that happens only for my ISP(FORTHnet).
For other ISPs all locations boil down just to Europe/Athens.
This happens to be because my ISP's network scheme is to assign blcoks 
of ip addresses per city in Greek area.

Same thing doesn't apply for others ISPs unfortunately here in Greece.

I have no idea how to implement the solution you proposed.
These are nice ideas we need to have a way of implement them within a 
script.

I have no way of grasping a map of cell towers of a  map of wi-fi hotspots.
