By default, a new ServerSocket should bind to all network interfaces. You should be able to find out what interfaces are being used by running (I assume you're running Windows, since you mentioned ipconfig):

netstat -an |find /i "8888"

If in fact the application is creating a socket and binding to all interfaces, you should see an entry like the following:

TCP   0.0.0.0:8888   0.0.0.0:0   LISTENING

Otherwise, you should be able to get the interface that is being used (it's the first IP address from the left).
