built and running .... let's wait to see what'll happen when this
notebook came from another network and tries to release a wrong
address on our network.
and thank you very much for your attention :)
Simon, seems its working as expected now.
this is TODAY's log

grepping this MAC address from my yesterday's backup shows that the
offered IP is the IP of the current valid lease
root@sede:~/backup/a/etc/dnsmasq# grep 00:1b dhcpd.leases
1270401733 00:1b:9e:4f:dc:fb 192.168.8.156 notevaldinei 01:00:1b:9e:4f:dc:fb
root@sede:~/backup/a/etc/dnsmasq#
so dnsmasq offered the IP on the current lease despite of the
'wrong address' situation. This seems to be OK to me, that's what i
would consider the expected behavior of a dhcp server in that situation.
