Why One DHCP Server Is Better Than Many
Why One DHCP Server Is Better Than Many (Real Network Lessons) Back when I was managing networks for a small ISP and a hospital, we had two separate DHCP servers : one for internet clients, and another for hospital/internal systems (HIMS). On paper, it seemed clean — different networks, different scopes. In reality? It was a maintenance nightmare . 😅 The Problem: Multiple DHCPs = More Trouble Running multiple DHCP servers in the same environment can create: IP conflicts – overlapping ranges can cause devices to fight over addresses. Routing confusion – packets might get lost between networks that don’t talk cleanly. Harder maintenance – every change has to be repeated in multiple scopes. Troubleshooting nightmares – one DHCP gives errors, another works fine… good luck figuring out which. I suggested a unified DHCP approach 10 years ago , but it wasn’t implemented back then. Fast forward a decade… and they finally did it. Imagine the frustration of seeing ...
