Using Pi-hole's DHCP for other network than Pi-hole?

Hi,

I have setup Pi-hole in network 192.168.1.0/24.

Question:
Can I use Pi-hole's DHCP service serving IPs in another network 192.168.100.0/24?

If yes, what are the pre-requisites for this? Must Pi-hole have an IP in 192.168.100.0/24 with an additional NIC?

The purpose of Pi-hole's DHCP is to automatically tell clients to use Pi-hole, and to have the client hostnames appear on the web interface. The DHCP settings support configuring only a single subnet. Pi-hole DHCP is usually used if the router's DHCP is not sufficient. Anything outside of these bounds is not something we can support.
