Unity's default networking, what type is it?

What is unity's integrated networking type? Is it peer to peer or is it 1 person being the host and the rest clients?

The built-in networking is a modified version of RakNet, and is client-server.


"The basic concept of networking is communication between multiple computers. To do this you need a client and a server. The server can either be a dedicated host machine for everyone, or a player running the game acting as the server for other players. Once a server has been established and a client has connected to it, the two computers can exchange data necessary for a multiplayer network game."
