nmap’s seeing the 1-9999 as the next argument (expecting an IP address). In -Pn, the n is a placeholder for the port numbers you want to scan, so you want -P1-9999
Maybe set up Kismet https://www.kismetwireless.net/
That’ll show devices attempting to break in wirelessly
… So when you port scanned it, IIS was gone?
You don’t have Ethernet over power do you?
Fun story, I live in a townhome, I had so bizarre network issues going on. Not able to stream to TV etc. finally started unplugging shit. Unplugged the router and saw the computer still happily downloading something WTF! Turns out a neighbor also had Ethernet over power and devices were randomly connecting to their network. Crazy ass shit.
I’m confused. Are you talking about power over ethernet or power-line ethernet?
There are Ethernet extenders that can utilize the power lines. They basically plug into an outlet and you stick an Ethernet into them and do the same somewhere else in the house.
Exactly, except mine was talking to the neighbors :p
It’s me. I’m your nextdoor neighbour. Sorry!
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.
Thanks. This helps. My work computer is way newer than that. It makes me think it could be networking hardware. I have some kit that’s about that old.
Get the MAC address from the ARP table, and look up the OIN, should help you determine if it’s virtual or physical, and if physical the type of NIC it’s using.
That gave nothing useful
The first few octets of the Mac address are unique to a manufacturer. This may at least help narrow which device it is. You can look it up at https://macaddress.io/
Sorry, I meant the OUI ( was going by memory ) . It’s the part that you can look up that tells your what kind of device the MAC address belongs to.
Thanks!
Did this actually help?
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.
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.
There’s Power Over Ethernet too.
nmap -A -T4 -p- <IP>
This is interesting. I had to modify it to nmap -A -T4 -p- -Pn <IP>.
It said the host is up with 0.077 seconds of latency. All 64k ports were scanned with 7 filtered tcp ports (host-unreachable) and the rest (no-response).
77ms of latency is pretty slow. Based off that I’d assume (but not rule out) that it’s not: on the machine you used to run nmap, not on ethernet, probably wifi with a shitty connection
So, some really dumb, likely irrelevant, questions that might spark an idea:
-
Do you see anything weird connected in the wifi client list? (You said it wasn’t given a dhcp lease, but it would still show as a wireless client even if it were static)
-
Are you running a VPN server or using VPN to bridge any networks?
-
You said you’re running dual WAN, are those configured properly and not leaking random internet shit into your LAN?
-
Do you have anything that might be running some kind of out-of-band management system like DRAC on a dell server?
-
What’s your IoT situation?
-
Do you have an on-site NVR for security cams?
-
Did you find the mac? If so what are the first 3 octets? Even if the vendor can’t be found, there’s always the chance some crazy ubernerd is going to recognize it. (If it’s 00:d0:2c or 44:d9:e7 I got ya covered)
Again, most of those are probably irrelevant, but throwing the thoughts out there :)

What’s weird about this is that it should be getting a response from IIS like you showed us in the screenshot.
There was an appliance where the wifi chip was at the end of the power cable, embedded inside the plug. From the outside, you couldn’t really tell. It was there so radiation inside the box couldn’t affect the wireless signal as much.
I can imagine some genius thinking it’s a good idea to run a server from inside a cable or a connected home appliance.
Sounds like purchasing got a deal on surplus spook gear.
Windows 8 is starting to break out
lol!
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
Maybe I want my vibrating dildo to take an hour to load and come with spyware
I have a Bluetooth controlled vibrator. Reverse engineered the app (which has a chat function) and it has a blacklist of words (mainly Chinese) you’re not allowed to text using the app.
I did not check if your horny chat gets copied to Chinese spy agencies, but I suspect that will be done on the server.
load and come
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.
blow
I mean, Windows already fucks us metaphorically
This is where you find that shit is so bloated and pointlessly connected that it’s running on a washing machine.
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 could be a configured one with the default greet page still up.
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.
Hmm. That would mean it’s likely one of the following (well perhaps more options, but these spring to mind)
- A windows machine that has the network set as a public network, or netbios specifically blocked on LAN.
- A windows machine that has all the netbios services disabled.
- Not a windows machine, or a container as others suggested that’s running some kind of IIS install
- Not a windows machine at all but for some weird reason IIS files and a web server setup.
I think you suggested in another comment, that it’s not in your DHCP client list but has an IP in your normal range. Which suggests it is setup with a static IP. That is odd.
Some other people suggested it could be a container that is using a real IP rather than the NAT that docker etc usually use. I do know that you can use real IPs in containers, I’ve done it on my NAS to get a “proper” linux install on top of the NAS lite linux that is provided. But I would have expected that you’d know about that, since it would require someone to actually choose the IP address to use.
If you have managed switches you could find which port on which switch the MAC address (as found by lookuping up the arp record for the IP using arp -a) is on (provided the switch allows access to the forwarding tables). Of course, if they’re on Wi-Fi it’s only going to lead to the access point they’re connecting to.
At least get WPA2
I don’t even think my current wifi kit has WPA (1) as an option. It’s WPA2 or 3 only I’m pretty sure.
