How to change Master Server IP and Port

Unity Engine
1

Unity built-in master server IP and port is unity technology itself’s physical game master server’s IP and Port, right?

Then how to change it to my own server?

For that, I must get(buy) server hosting and coding change to that my server’s IP and Port?

Then for this, I must setup own master server file in this page?

Then for this, cuz I use window7 environment, I need perform this sentence?

Then for this implement, do I need Visual Studio 2008 for build my own server?

And why official networking sample project’s ConnectGui.js uses network’s IP as 127.0.0.1?

Isn’t it my local laptops IP? Why it uses that IP? Then default unity’s master server does not related with IP and Port?

Unity provides all the commands in the documentation. instead of posting for them in the forums you could just look in the docs and find them yourself.
If you want to build the masterserver you will need to compile it so indeed you will need VS to achieve that.

Unity examples have that ip because they know it will allways work when you test it on a computer.
It’s impossible for them to make examples for your network configuration.
