That is weird. Running development environments maybe? Docker with windows iis?
The only windows box on my network is my company laptop. It is on a different IP address than that one.
It IS in my normal range, but it is NOT listed on my Router’s DHCP client list.

I have x-code loaded on a Mac, but that is the closest I have to that.
oracleunity@lemmy.world 2 months ago
Yeah, that’s a company server, specifically for the local network group
It IS in my normal range, but it is NOT listed on my Router’s DHCP client list.
Why would an internal server change IP all the time? DHCP is for silly things like laptops that turn on and off eleventy times a day

Even if it isn’t changing IP, you still want it in your DHCP table so that IP doesn’t accidentally get assigned to something else. It’s unlikely but it can happen.
RestrictedAccount@lemmy.world 2 months ago
Thanks! I did not know DHCP allocation was optional on a home network.

The router might have a page for fixed IP addresses.
RestrictedAccount@lemmy.world 2 months ago
It does, and it’s not listed there.

“home” isn’t descriptive enough. you can run some VERY powerful, in depth stuff if you were so inclined on a “home” network.
RestrictedAccount@lemmy.world 2 months ago
It is more than your average home network. I have a dual WAN router with fiber on each to a different provider. (It is stupid overkill, but my wife and I both work from home and it is important not to be down). I use a pi-hole for ad blocking and unbound for recursive DNS resolution. Most of the devices are wired Ethernet, so I have a bunch of switches and kit to transform coax into fast Ethernet.
I don’t mess with the firewalls, because that seems like there is a big downside to messing about if you get it wrong. That is all vanilla out of the box.

Any device can decide to set it’s own IP so that’s not too far fetched. Have any IoT crap like a water softener or colorful lights or speakers or cameras?
RestrictedAccount@lemmy.world 2 months ago
I have quite a few smart home devices. But the only “crappy IoT things” is an air purifier that is controlled by phone.
Unfortunately, I bought quite a few T-Link products before the IC revealed that they are dangerous.
It is worth exploring.
mvirts@lemmy.world 2 months ago
Ah I have a TP-link router as well, two actually, and Im not monitoring my home network at all. Your experience makes me think I should!

Have you recently installed visual studio or are doing any .NET development? It could possibly be a containerised version of IIS
If you completely turn off your windows device and try to access the IP from another device does it still resolve?
RestrictedAccount@lemmy.world 2 months ago
Great Idea! My windows box is off and I can still see it from my phone.
9point6@lemmy.world 2 months ago
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.phpI 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.
Agent641@lemmy.world 2 months ago
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.
