How to modify the Android emulator IP address of eth0

I used Android4.0 simulator tool chain now offers Android compiled a program already running in the adb shell mode. I need to get this process simulator eth0 IP address and then interact with the server, but I installed busybox, and then view the eth0 address of 10.0.2.15 with busybox ifconfig command (#. / Busybox ifconfig), my server address 10.96.XX.XX is a public network IP, can not communicate between them. (Note: The simulator can directly access)
Used setprop command and sqllite3 other methods will not work.
How to modify the simulator eth0 IP address ah? (Direct eth0 10.96.X.XX netmask 255.255.0.0 not use ifconfig, the simulator directly unresponsive)? Do you want to get root access module's? Has been trying to root, but unsuccessful, please enlighten me master!!
