Quake3 Master Server For Windows

hey. I've maanged to compile Quake1, and Quake3.

But i have 1 question... I've looked inside the QuakeIII source code, and i've seen this to connect to the master server.

#define MASTER_SERVER_NAME "master.quake3arena.com"

I was wondering, because I want to make my own game, If i could make a master server oor do you just type in the name of your server ?

Is it an application something? Or do you just link it to your server? or Web server ?

Can anyone help me?

dpmaster can run Quake3 compatible master servers.

ye, i've run thew .exe. Its a command prompt. What port does it exactly run on?

Is it 820? I need to set this in the code.
