UPDATE 10/4 6:47 EDT

I have been going through all the comments. THANKS!!! I did not know about the techniques listed, so they are extremely helpful. Sorry for the slow update. As I mentioned below, I got behind with this yesterday so work cut into my evening.

I ran a port scan. The first syntax, -p, brought no joy. The nmap software itself suggested changing to -Pn. That brought an interesting response:

nmap -Pn 1-9999 <Local IP Addr>

Starting Nmap 7.93 ( https://nmap.org ) at 2024-10-04 11:44 BST Failed to resolve “1-9999”. Nmap scan report for <Local IP Address> Host is up (0.070s latency). All 1000 scanned ports on 192.168.0.46 are in ignored states. Not shown: 990 filtered tcp ports (no-response), 10 filtered tcp ports (host-unreach)

Nmap done: 1 IP address (1 host up) scanned in 6.03 seconds

Just to be absolutely sure, I turned off my work computer (the only windows box on my network) and reran the same syntax with the same results.

As I read this, there is definitely something on my network running windows that is not showing up on the DHCP.

    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.
