Windows Server 2008 R2, running the DHCP service.

DHCP Scope: 192.168.1.1 - 192.168.1.254
Exclusions: 192.168.1.1 - 192.168.1.99

If a reservation uses an IP address in the exclusion range (like 192.168.1.42), what will happen when that specific client makes a DHCP request?
Will it get the reserved address (even if it's excluded from the scope) or will it get another, casual one?

  • Explanation: I want to exclude a range of statically-assigned IP addresses from DHCP, but I also want some network printers which are automatically configured with DHCP to get a fixed address in that range. – Massimo Nov 17 '11 at 20:27

It will get the address. In one network I manage all of the reservations are in the excluded range.

From the technet docs.

Reservations can be created using any IP address in the scope’s address range, even if the IP address is also within an exclusion range.
