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.
It’s the default page for a Windows Server running IIS web server.
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.
Edit: here’s how to disable that web server https://superuser.com/a/1377078 . I’d do that on any Windows machines as well.
This is where you find that shit is so bloated and pointlessly connected that it’s running on a washing machine.
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.
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.
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.
The default home page for Microsoft IIS, the web server built into Windows Server (and probably some desktop builds too).
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.
How insanely small was the transfer? Like 1 bit?
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.
Is your IP adres same as localhost and you are using Windows Pro, then probably IIS is installed on your device.
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?
Following, I want to know what god awful iot device this is. Refrigerator? Toaster oven? Vibrating dildo? The suspense is killing me
