Go into your start menu and type in cmd, open that program and type in Ipconfig, scroll up until you see IPv4 Address. Copy that number to your clipboard and put it somewhere you won't forget. Now you have the IP address you'll need to host the server.

Now that you found the IP address, open Magicite and go to multiplayer. Type in your IP address and press host. It will ask you to make your character and by this time players will be able to join your server.
