[Dnsmasq-discuss] How to configure 2 different nets: 1 guestnet, 1 "known-host net"?

I try to configure two IP ranges:

"known host net":
192.168.8.x for "known hosts": Host with a known MAC address and a fixed
IP address.

"guest net":
192.168.9.x for all unknown MAC addresses. Hosts in this net just get a
short-time (1h or so) lease from a dynamic IP range pool.

So I added several lines for my known hosts:

dhcp-host=00:11:22:33:44:55,workstation,192.168.8.10,24h
dhcp-host=11:22:33:44:55:66,notebook,192.168.8.12,24h
etc.

and one dhcp-range for the guest net:

dhcp-range=guestnet,192.168.9.100,192.168.9.199,255.255.255.0,1h

The router (that also runs dnsmasq) has (at the internal network
interface) the IP addresses 192.168.8.1 and 192.168.9.1 (I plan to use
VLANs some day, at the moment both IP subnets share one physical network)

The problem: All hosts always get IP addresses from the guest net. The
MAC addresses are verified many times so ... why don't get the known
hosts their right IP address? How can I fix that?

Greetings,

                  Lars R.
