How will the resolver know whether "patrick1" (example host from my
earlier email) is a meant to be resolved via a local or an upstream
server?

I wasn't sure how you set up your systems, so I gave a (possible)
solution with dnsmasq on the clients and one without.

I looked for "man dnsmasq.conf" but it doesn't seem to exist.

You can override the Fedora-supplied dnsmasq.service with a systemd drop-in.

I've just downloaded and expanded the dnsmasq rpm. Going through
"/etc/dnsmasq.conf", IIUC, for my previous example:

server=/poc/192.168.1.111
server=/1.168.192.in-addr.arpa/192.168.1.111
local=/poc/
