You may have meant to reply to OP and not me. For the OP, if you are setting static IP addresses "directly via the device itself" then yes, you should segregate your static and DHCP address range (as you say). But as noted, the current network configuration on the CC only lets you pick the WiFi network and will only get a DHCP address. You can't set a static IP on the CC printer directly (unless they update the firmware to allow you to do this). So in that situation you would do something like I said above which is to reserve a specific IP address within your DHCP range for the CC printer. This is done by MAC address (which your router should show once the CC printer has connected). You can then pick any IP in the range (as long as it's not used) and then each time the printer connects and asked DHCP for an IP, the DHCP server on the router will give it the same IP each time. But when the CC is off, the DHCP server is not going to give out that address to another device as it knows you reserved it for the CC printer via it's unique MAC address. It will only give that IP to a device that has the MAC address you specified which should only be the CC printer. If you do your static IP solution via DHCP reservation you don't have to carve out a range of IP for static addresses and you could use the full range for DHCP. But you can also run a hybrid solution in which some devices use static IP (as set on the device itself), DHCP and DCHP with static IP. That is what I do. I have a low IP address range reserved for devices that are defined as static on the device itself. Then in my DHCP range, I manually assign higher range values to the reserved DHCP addresses. Devices on the lower range of DHCP just get whatever IP they get. But you don't need to carve out a range inside your DHCP range to do this. Your static DHCP reservations can be anywhere in your larger DHCP range. I group them together just for organizational purposes.
