Questions about UNET Networking

I'm trying to understand the new UNET Network system.

• I downloaded the Lobby Matchmaker asset example and I want to know if I creat a game, the creator is hosting this match or the server is hosting this match ?

• Unity available 100CCU for users, but thats dont means that it will host this 100 players for you right ? How can I set up a dedicated server for the entire game ?

My needs:

• I want to make a turn per turn game with 8 peoples per room. One of them created the room (match), but i want that a dedicated server control this room, not the player that created the room. Is this the best way ?

• How can I host this game with a server ? I saw old system of network that runs the server with the prompt of windows (CMD), I read the documentation but I dont think I understand.
