Is there a way to find the IP address of the desktop machine connected the android phone after USB tethering is turned on?
Does android assign a fixed IP address to the desktop? Or does it assign a dynamic address (dhcp)? Is there a PPP connection created between the phone and machine?
With USB tethering it seems that all android devices use the same static addresses, the android device using tcpdump is 192.168.42.129
The attached device will get a DHCP provided address in the same address range.
I listen to a port on my android app and have a udev rule to push the dhclient address back to that port on my app.
AFAIK, in usb tethering mode the phone is acting as the computer's modem, so the PC's IP would be the phone's IP.

Is there any way to set a static IP address to Android device if the device is connected to a network via ethernet cable using ethernet to USB adapter?
I tried connecting to device via ADB and then changing IP address using $ ifconfig eth0 x.x.x.x command, but I got ifconfig:ioctl 8916: Permission denied as an answer.
Nope, there is no way to set it on common devices. You need rooted device, which allows you to run ifconfig eth0, thats the only way (valid up to Android 13). By default eth0 will obtain IP using DHCP, if there is no DHCP available - it just won't work. In "your" network you may assign some particular IP for particular MAC (also ensure that MAC address of ethernet isn't randomized like for Wi-Fi starting Android 10, but it shouldn't be on Linux level)
I followed all instructions found here: https://developer.android.com/studio/command-line/adb, still can't find my device's IP address, because it's unavailable:
What could I possible do? I don't want to root my phone, and I can't run the emulator on low-end PC. And BTW I'm using Alcatel... The USB cable was borrowed... Please, help!
For wireless debugging to work phone and pc should be on same network. So one thing you can do is to create hotspot from mobile and connect your laptop to that hotspot.(You don't need internet for that)
When you get connected to a network IP address is assigned to your device.
Setting static IP Address(192.168.55.155) on android device, results in its WiFi connection not working (no internet).
If its DHCP on the android device, WiFi (internet) works. The Gateway on the device is pointing to Wifi Router.
I have a few android devices on the WiFi router. I need to know the IP Addresses of these devices in advance, so having static IP address is one way.
What configuration is missing?
You cannot give it a fixed address of 192.168.55.### when the router gives you one like 192.168.0.### but only 192.168.0.### also. Try 192.168.0.155.
Its easy, use an APP called Fing this APP allows you to watch all devices connected to your network and their IPs.
I'm debuging an android application using my android smartphone (Sony Experia) and I need to connect to the computer's local host through the android app I'm developing. I tried several methods (USB tethering, Wifi hotspot) but I couldn't achieve it. Please support me with a solution. I know that simply 10.0.2.2 is working well on the android AVD but I've no idea about real devices.
I'm using Microsoft Internet Information Services (IIS) as my server and the web application is also running well. I don't know whether the firewall is blocking the port or not.
This should work:
Unplug all the network cables on the computer and turn off your wifi.
Turn off the wifi on your Xperia.
Connect your Xperia to your computer via USB Turn on "USB Tethering" in the android menu. (Under networks-> more...-> Tethering and portable hotspot")
Get the IP of your computer that has been assigned by the USB
tether cable. (open command prompt and type "ipconfig" then look
for the IP that the USB network adapter has assigned, It is Under 'Ethernet Adapter Local Area Connection' title. The Value for the IPv4 address is the One you need.)
Open a browser on the PC using the IP address found instead of
localhost to test. i.e.
http://192.168.1.1/myWebSite
Open a browser on the android and it should work.
If it is working on your PC but not in your device, You have to allow your http through firewall.

Our university (school) has a limitation that one can only connect to their network using one device per student. It has been put in place because of the poor connectivity here (I'm in South Africa). I have set up my mobile (android) as my connecting device and when I tried to use my laptop on the network by tethering on my mobile I couldn't connect. I'm guessing the IP address is checked and, since the laptop IP is different, it won't let me in.
Any idea how I could get the laptop's IP to be the same as the phone? We are instructed to use DHCP and I'm using windows on my laptop.
