Comment on I found a weird IP address on my network that had transmitted an insanely small amount of data. I put the address in my browser and got this. what the heck am I looking at?

  Hmm

  I’d maybe try systematically turning any other devices off you think could potentially have the grunt to run windows server in a container or VM.

  Do you have a Mac/Linux machine handy? If you run arp -a in one terminal and ping the unusual IP in another, that should give you a corresponding MAC address for the device. You can then look up the Mac address and see if it gives you any more info about the device running it—it might not but you never know. You can use something like dnschecker.org/mac-lookup.php

  I guess next you could look at taking that MAC and blocking it in your router control panel and see if anything starts complaining

    I love the “see who screams” method, my coworkers do no. it’s usually instant.

    In addition, you might like to do a portscan on that IP address to see if any other ports reaveal something more interesting.

    You can run this in cmd prompt, I think, if nmap is available on your windows machine:

    nmap -p 1-9999 192.168.1.1

    IIS can only run on a windows OS, so it must be a windows physical machine or VM connected to your network.

      Thanks as you can tell, I’m not an expert in any of this.

      I will run this as you described.

      I did the nmap based on input from ChatGPT, it had me do a Ping base scan with nmap. It turned up nothing because that IP address did not return a Ping.

      This has me really curious.

      I’m concerned that the website I opened in Safari on my phone is bringing up a cache on my browser and is not actually live.

      I tried to open it from an iPad and it did not load. Iit still loads off my phone even though I have rebooted everything.

        In case it helps your troubleshooting, ICMP (ping) is typically disabled by default on Windows.
