I inherited a Class B network years ago and am just now wanting to do a major overhaul. Currently the LAN network is 10.1.0.0/16. It is currently just a flat network with servers and clients dispersed throughout. I want to segment the network into the following categories: Servers (25ea now), Workstations (100ea now), Printers (30ea now), Utility devices (20ea now). All of our wireless clients are connected on the outside of the firewall and are outside the scope of this question. Our firewall is a WatchGuard device.
Should I rework the ip address scheme? If so, can someone layout an example of what I should do?
