+## Get IP of Device
+We have to get IP of Device, because another PC need this for connection.

+If you connect your device to router with ethernet, pass `eth0` to below command to get IP address of device.
+```bash
+adb shell "ifconfig eth0 | grep 'inet addr' | cut -d: -f2 | awk '{print \$1}'"
+```
+
+If you connect your device to router with WIFI, change `eth0` to `wlan0`, like:
