Trying to build a multi like on rust

I'm trying to build a nultiplayer game like rust and I have no clue where to start.
I tried to use google and they game me photon wich is awesome but it is not what I want.

How can you do a multiplayer game wich everyone can open their own server and be the host?

and not on photon's servers.

 

Cant you just use Unity's build in network solution?

 

check for bolt or tnet

 

But they work on unity's master server no?

 

So... Googled "What networking does rust use"

1st result

It seems there using uLink and unhappy with its response time on closing exploits.

Sorry for referring back to this thread everyone who's seen me posting it occasionally. http://forum.unity3d.com/threads/an...t-to-version-4-networking-what-solved.258276/ is where I grappled with the unity networking possibilities.

At this point as I understand it every main networking package that runs a server the dev can run (including photon which lets players host) runs runs off a copy of unity
