    Mysterious IP on my Wifi

    When I enter my router and get list of devices on my network, there's one IP address i cannot recognise. It's connected via wireless 2.4 Ghz. If I try to open it in my browser I get "refuses to connect" so there is something there. If i go to command prompt and enter IPconfig %IP address%, I get no details. If I go nslookup %IP address%, I get server unknown ???

    All I want is a hostname ! any name ! any hint what this device is, I'm racking my brain. I've turned devices on and off with no help.

    Is it an internet radio? I have one that seems to show up as Unknown device.

    IPConfig is a local command and as far as I know can't be used to pull info from remote hosts. NSLookup is for DNS querying, so if the host has no DNS name configured this won't work either.

    What's the IP address, and what is your home network subnet range? For the last one provide the output of "ipconfig /all".

    Are you able to connect to your router via web browser or terminal? If so, what brand + model is it? You might be able to view host info from the routers GUI/command line.

    You can also try to pull info on the host using NMAP - it's a safe and free network scanner, found here: Download the Free Nmap Security Scanner for Linux/Mac/Windows - This is one of my go-to tools for anything like this. If you do this, feel free to share the output here, too.
