Every computer runs the client. It creates a Techscale network adapter and sends the private range through that adapter. Leave the client running while that PC should stay on the network.
The office LAN stays as it is. Techscale addresses are separate. A client that reconnects with the same key gets the same address. The range cannot be changed while clients are stored.
The owner gives each customer a separate range and auth key. A range already given to one customer is refused for the next. The range works for 7 days, then the owner activates it.

100.64.0.1 first computer 100.64.0.2 next computer
A new range works for 7 days. After that the owner activates it, and the same computers keep their addresses. A range already given to one customer cannot be given to another.
