It's intended that names-addresses from DHCP should override
address=/<domain>/, yes, and if a machine is called "protonet" then that
name will override the address you've configured.
There are at least three approaches that will fix this. If you don't
care about names for DHCP hosts, add
to /etc/dnsmasq.conf. That will stop dnsmasq adding the names of any
DHCP hosts to the DNS.
If the problem is just one machine, you could add
dhcp-host=<alternative-name>,<MAC address of client>
to control the name given to that machine.
Alternatively, do something like
That will stop the DHCP machine having the name "protonet" (and stop the
override) but it will still have the name "protonet.example.com"
This change will apply to all DHCP names, of course.
