How can I get the IP address, MAC address, etc. of a user connected to a Wi-Fi hotspot? ( Using Karbonn A21 Phone running Android 4.0.4 with minor changes to the skin)

  • Is this your wi-fi hotspot? Like... are you turning your phone into a wi-fi hotspot?

  • Yes, I'm talking about the hotspot running on my phone.

  • What's your phone? Your question might be a duplicate of mine's: android.stackexchange.com/questions/18529/…

    @geffchang you might want to try my suggestion (see answer below). As those port-scanners are supposed to scan the network they are in, they should work in both cases. Maybe you can confirm that it works from the hotspot itself -- for the other case I'm pretty sure :)

  • @Izzy All right. Will check it later when I get home.

Take a look at Network Discovery1 -- it lists all devices within the same network, together with some details on them, as e.g. IP, MAC address, available services:

Network Discovery Network Discovery
Network Discovery (source: Google Play; click images for larger variants)

Other port scanners will do as well.


1: This app is no longer available on Play Store.

  • Does it scan the WiFi hotspot the phone creates or/and the WiFi network to which the phone's connected ? (I'm asking this because I don't have my phone right now)

    It does scan the network the device is in. I don't think it matters if it itself is "master" or "client" in the network -- but I never tried.

  • It would be needed to enable in options 3G scanning.

  • @Vadzim not much chances. I'd bet port-scanning is blocked there by the providers/carriers for good reasons. Apart from that, the question was about WiFi, not 3G ;)

  • @Izzy, I was solving the problem of finding MAC of one device connected to Wi-Fi hotspot of the second device. The first device was in process of initial setup not allowing to view MAC from inside.

Another alternative is Wifi Watch.

    Could you elaborate a little more? Link-only answers are not considered that helpful. What details does it offer?

  • Sorry! but the questions says that it should work for mobile as hotspots. Wifi Watch is not for that. It scans if your mobile is connected to wifi hotspot
