Problems with Kega Fusion emulator

[newguy]

Hello there,

You might,or might not,have heard of this thing. It's a Sega emulator,which also allows Netplay.
The problem is,the netplay doesn't seem to work.
All it needs,is an IP address.However,i can't seem to find an actually working IP address,neither the "cmd" or www.whatismyip.com gave me what i need.Even Hamachi doesn't seem to do it right.
Surprisingly,it allows me to join my own server without a problem.

What should i do?
