DHCP is not reassigning (back to first ip) after last ip was used when FlatDHCPManager as shown on dnsmasq. Both dnsmasq programs show: --dhcp-range=192.168.1.96,static,120s when I have specified --fixed_range=192.168.1.96/28 and --network_size=16 and --fixed_ip_disassociate_timeout=60 I think the --dhcp-range should be: 192.168.1.96,192.168.1.111. Also the --flat_network_dns parameter is ignored, I have to enter the dns via mysql cmd. Thanks for the help

So that means that the dnsmasq for Flat_dhcp does not provide DHCP server services? it means that I have to provide a DHCP server on that network?

On current trunk ips should be recycled after 10 minutes. Flat_dhcp doesn't use the dns command from the database. Dnsmasq functions as a dns server and it uses whatever is set on the network host. If you would like dnsmasq to use a different dns server you can use the following flag in nova-network: --dns_server=<dns_server>

Dnsmasq supplies dhcp server services as well.

arturo lorenzo is still having a problem: So that means that the dnsmasq for Flat_dhcp does not provide DHCP server services? it means that I have to provide a DHCP server on that network?
