Guess who managed to assign the same IP to two devices and spent the last hour trying to figure out what was wrong 🙄

Me ?

Did Windows 10 crash? Where are the screenshots?

¯\_(ツ)_/¯

Don't you usually get a notification saying that there's an IP address conflict?

It's a pretty exotic setup. My NAS (Ubuntu Server), Raspberry Pi (LibreELEC) and laptop (Windows 10) are connected through a switch with static IPs. But my laptop is also connected to the router wireless with DHCP.

I assigned the addresses to all devices, but while I could ping my laptop from the NAS, it didn't work the way around. Turned out that the Pi and the laptop were given the same IP, which ipconfig flagged as duplicate. However, I have no idea why I could successfully ping the duplicated IP from the NAS, but not the one that was fine (the NAS).

What's even more fun is when you manage to somehow have two DHCP servers in your network and nobody and everybody gets an IP.
