find who owns teh IP... from a machine on teh same subnet: arp -a (Windows) or ip neigh (Linux) shows the MAC for teh address after you ping it. look up teh MAC vendor prefix and check teh switch's MAC address table to find teh port. hope that helps :)

    help!! small office, 172.16.10.0/24 network. Since last week the conference room TV disconnects every few hours, and a nearby PC shows this:

    Network & internet

    Network & internet
Wi-Fi  •  HomeNet_5G
No internet, secured

Connected, but nothing loads. Troubleshoot problems?

    rebooting fixes it temporarily, nobody admits to changing anything. I suspect something has teh same IP, but how do I find out what?

    we don't have a proper network diagram, and teh person who set up most of the devices left a while ago. i'm teh 'IT person' because i'm good with computers, any simple way to find the duplicate would help. pls help 🙏
