Generally speaking LANs are considered to be part of the Internet if they have via routers/gateways connectivity to the rest of internet. Internet is a connection of networks, and not all of it is public. The fact a device does not have direct connectivity to other networks does not necessarily mean it does not use internet connection. The SPOT device uses internet connection to reach devices of the tracking family. -- Poutnik ( The Wanderer ) My Brouter profiles https://github.com/poutnikl/Brouter-profiles/wiki -- You received this message because you are subscribed to the Google Groups "Osmand" group.
