One of my clients told me their company's LAN kept disconnecting intermittently. Everything seemed normal, and it was really hard to catch the exact moment the connection dropped. 🫤After many tests, I still couldn't pinpoint the issue. I had to patiently go through the logs on key network equipment. Finally, I spotted this line in the main router:

18582: IP binding conflict: host MAC address xxxx on this LAN is trying to use IP address 192.168.1.1.

Now the problem became: how to find that host. The easiest way was to ask the staff if any new equipment had been connected😆—much faster than unplugging cables🔌 one by one. Soon, that bitch device was found.⚡⚡
