@hellomiakoda Sensible.
I have split my network in 3: LAN, WLAN, DMZ. I allocated a /23 to each of them, with the gateway on .0 in the middle. That last point is just to trigger people who believe a host can't have a .0 IP address.
Everything is configured through DHCP, with the pool being the low half of the network and the fixed IPs the higher one.
The switch an AP have dynamically assigned IPs, because UniFi allow me not to care. Printer is on WLAN's highest possible address.
