Spoof IP for only 1 subnet

Installing and Using OpenWrt
1
  1. I have a few subnets for guest, IoT, home and work
  2. I spoof some of my hostnames with an internal IP 192.168.1.x so that in the event the internet goes down, their connectivity do not get affected
  3. Can I only spoof them on work while the rest will resolve to my WAN IP?

yes, but you might need a separate dnsmasq instance to make it happen.
