It’s the default page for a Windows Server running IIS web server.
As everyone else has said this is the out of the box default page that comes with Microsoft IIS web server on windows server.
Though I feel like you’d know if you had a copy of windows server running on your network somewhere—is the IP in your usual network subnet?
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.
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?
Great Idea! My windows box is off and I can still see it from my phone.
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 -ain 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 https://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
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 192.168.1.1IIS 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.
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.
That is weird. Running development environments maybe? Docker with windows iis?
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
Thanks! I did not know DHCP allocation was optional on a home network.
The router might have a page for fixed IP addresses.
“home” isn’t descriptive enough. you can run some VERY powerful, in depth stuff if you were so inclined on a “home” network.
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 on a small network but it can happen.
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?
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.
Edit TP-Link
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!
You can enable IIS on almost any windows flavor.

The default home page for Microsoft IIS, the web server built into Windows Server (and probably some desktop builds too).
So, as others have saId this is just an unconfigured IIS server, which implies it’s either a windows machine, or a windows based VM, well or someone put the default IIS files on another server, but that’s unlikely.
When you say “weird” IP I’d wonder what you mean by that.
I think since it’s probably a windows machine, from another windows machine typing nbtstat -A <ip> should give you the computer name and workgroup or domain they belong to. See if it matches anything you expect on your network.
If not, maybe it’s time to change your WPA wifi key.
At least get WPA2
Thanks. I ran nbtstat and it came up empty.
Edit: Also, I am big on wired networks. I mostly save WI-FI for smart and mobile devices. There is a lot of stuff on Ethernet that does not need a password.
Following, I want to know what god awful iot device this is. Refrigerator? Toaster oven? Vibrating dildo? The suspense is killing me
Nobody wants windows on a vibrating dildo
I mean, Windows already fucks us metaphorically
Maybe I want my vibrating dildo to take an hour to load and come with spyware
Hey, I’m not normally one to judge but it seems like a bad idea to call yourself spyware. Either you’re going to blow your cover or it’s just negative self talk.
If you can, power stuff off and check if that web page is still available. Start with any Windows machines. It could be a virtual machine running inside of something else though.
The mac address can also tell you the hardware vendor.
does your router give you the MAC address of the device? You can look it up to see who manufactured it and then narrow down. This could be a device that has a web service running is all you are seeing right now.
Don’t need the router. If you’re on windows or linux, you just ping the ip then enter ‘arp -a <ip>’ it will show the MAC address for the IP from your machine’s arp cache.
It does not show up on the DHCP table, nor does it reflect pings.
You can always start looking at how to use WireShark to sniff the packets and learn more about what is coming and going from that system. WireShark can be a daunting tool but if you look at some videos or walk through you should be able to get a handle on how to make it reveal only the one devices network traffic
I have Wireshark, but haven’t really had a reason to learn it. I mostly just stare at the traffic rolling by the way they do on The Matrix. This is on the list to try.
Home network or corporate?
Its a windows server, if you are using widows too you can try establishing a RDP connection with Remote Desktop Connection.
Yeah and giving a potential attacker your account details while trying to log on?
Eyeballing the login screen may give some insight, you’re right that its probably unwise to try real creds if you don’t recognize the server.
This is where you find that shit is so bloated and pointlessly connected that it’s running on a washing machine.
How insanely small was the transfer? Like 1 bit?
9 packets
That is IIS, all it means is you are probably talking to a windows server. Is the traffic encrypted? What port is it going to?
Is the traffic encrypted?
If it is, look at the certificate. Which hostname is it for primarily? Which SAN (Subject Alternative Name - basically a list of all other hostnames the certificate is valid for) are set, if any? Which Certificate Authority issued the certificate or is it self signed?
Depending on your router, it could have a docker setup with Windows on it. I’ve seen some strange shit on cheap routers with far too much processing power and storage.
I will probably have to shut all the devices off and put them back one by one. OMG that will take a long time.
Others haven’t suggested this yet, but a single device, like your laptop, even with one connection, can have two IPs.
Thanks. It is neither the Ethernet nor the Wi-Fi on my windows laptop.,
Don’t just turn your devices off when testing - - unplug them. An off computer can still respond to network requests.
I did not think of this. I will have to go into the bios to turn off the battery of my work laptop.
Windows IIS probably from around the time of windows 8 so maybe 2012. Probably running on either windows server 2012 (like exchange, an active directory domain controller, or if you are unlucky sharepoint) or some weirdly configured appliance running windows 8 ish enterprise.
Bro, you gotta keep us updated, I’m surprisingly invested in this now.
I lost my entire morning to this yesterday. I had to work late to catch up. There are some good ideas in here I’m starting on now.
