Q & A

Split-Scope DHCP Servers
by Scott Morris

10/28/08

Scott,

This may not be a tough question but I can't find an answer to it anywhere else. Basically, I'm curious to know what happens if I have two DHCP servers configured in a split-scope. If one DHCP server runs out of addresses, will it still respond to DHCPDISCOVER requests?

I'm worried about implementing a split-scope with, say, 100 addresses in each scope (200 total) and 150 clients. If more IPs are distributed from Server A than Server B, what happens when Server A is full? Will clients just get one from Server B (Server A no longer responds) or will Server A respond and give an address of 0.0.0.0?
