That DHCP reservation that took me 4 hours to debug

I spent last Tuesday chasing a network issue at a small office in Austin. Turns out the printer kept dropping offline because someone had set a static IP that overlapped with the DHCP pool. Took me 4 hours to notice the conflict because nobody labeled the device on the network map. Has anyone else dealt with dumb overlap issues that should have been caught in 10 minutes?

Did you already check if the DHCP server was logging those overlaps? Seems like a basic thing to turn on but half the time people skip it.

Wish I'd remembered that before spending hours chasing ghosts.

Yeah, "basic thing to turn on" is exactly right, I learned that one the hard way too.
