Device on network that I am not sure about.

This device shows up as an ethernet connected device. Do you know what it could be?

Re: Device on network that I am not sure about.

Well I can tell you it's a PC named "Mindless-PC" 

It's IP address (LAN) is 192.168.1.65

 

per this link: http://www.coffer.com/mac_find/?string=00:18:8B

 

It is a DELL assigned address. So the MAC is not spoofed or appears not to be. 

 

Maybe check around and do an IPconfig on the devices and look around?

"Dell ESG PCBA Test" is apparently a stock manufacturer's decription for a MAC address prefix of "00:18:8b".  So, apparently it's something made by Dell.  A PC, Tablet or PDA, perhaps.  You could check all your Windows PC's by opening up a command window and entering IPCONFIG /ALL and searching for a Physical Address that matches the above.

 

You can also check your Windows System name under Computer > Properties

 

If it's not in your home, then it may be from without using wireless.  Change your Wireless security settings.

Re: Device on network that I am not sure about.

Hi. I really appreciate your time. I will give you more info tomorrow when I can access the network. It is at my workplace. I have shut down all devices I am aware of to find the device. I will post screenshots of scans, if it is okay to do so tomorrow. Thanks for your time.

This is an IP scan of network devices. The checked are active. The one named "unknown" is accounted for. The bwright-pc is a Dell Laptop I am using.  If I think of any more info I will post later. Thanks for your time, Buck Wright

Not sure if this info will help or not.

Clearing the device list will not clear any devices which have host application mappings. Other per-device settings you may have made (IP addresses, Content Screening,etc) will be cleared. It is recommended you only do this when instructed to do so by customer care.

How is it a ethernet connection and you dont know which device? a Little confused here. It seems you only have 2 Ethernet connections.

Re: Device on network that I am not sure about.

Could it be a Dell networked printer?  Or some sort of Dell print server?

What ever it is, it's physically connected to Port 4 on the RG.  Shouldn't be that hard to find.

The way is is wired there is no way to follow it. There are about 20 others bundled with it and then goes into the ceiling. The Port 1 is for our security system. What I can't figure out is the Dell part. We have no machines that are Dell other than PC's. I guess I may need to ask the people who installed the system. Thanks again for your time.

Unplug the cable in Port 4 and see what quits working.  Leave it unplugged if everything YOU have still seems to be working.  If someone complains, you will know what it is then!!

 

If your in an office building or someplace with multiple tenants it could be a left over cable going to another tenant's location and was plugged into your network by mistake.  They don't know so they plug in their computer and they just decide they got a bonus because it's working.

 

For instance, in my office suite we have the main distribution frame (MDF) for our suite and it used to feed the suite next door when it was one big suite.  We moved in and they just put up a wall to divide the office and make it 2 suites instead of 1.  All of the old cabling from that suite still runs back to our MDF and is terminated on a patch panel.  If I plugged one of those cables to our switch it would work in the suite next door.  Just wondering if this might be your situation.

Re: Device on network that I am not sure about.

We are the only ones in the building. The owner really has no idea about technology so asking her is useless. I may try the unplugging idea. My luck it will do something that shuts us down for a week. I will probably just ask the people who put the system in. I will post the answer when I do so. Thanks again for the input.
