[Dnsmasq-discuss] Removing a feature does anyone rely on this?

May be.
But our experiments failed.

We wanted

        dhcp-range=192.168.0.10,static,infinite
#               (192.168.0.0/24) for the school computers
        dhcp-range=192.168.18.10,192.168.31.250,30d
#               (192.168.16.0/20) for the private machines

and defined all school computers via "dhcp-host=...".

Sometimes/often they got IP adresses from the "private" net.

Adding/changing

        dhcp-range=eth0,...
        dhcp-range=eth1,...

didn't help.
There is a third NIC for the DSL/Router, defined as

   no-dhcp-interface=eth2

Viele Gruesse!
