Using IP to ping a real Android device that is plugged by USB from computer I plugged my Android tablet to the computer with USB cable and looked at the IP of Android device and tried something like ping 160.xxx.yyy.zzz on the computer. There is no response.

I wonder, does being in a huge network that prevent one machine to see the other one affect to 
pinging from one machine to another, even they are connected by a USB cable?
If your network is correctly setup, and both devices are on the same network then you can ping an Android device just fine. I've just tested it on my office network.

If your network administrator has configured the network such that devices can't ping each other, then obviously it won't work. Similarly, it probably won't work if your phone is on mobile data, since most carriers don't allow incoming pings to devices on their network.

Connecting the device with USB makes no difference at all: pinging is a network operation, so it goes over the network connecting the two devices.
