shared-network

[Laszlo Fekete]

Thanks.

Just another question: I have some clients without fixed address and
they get ip dynamically from 192.168.5.0/24 , so this stored in
dcpd.leases. But later give them fixed address from 160.1.2.0/26. Is it
possible if the client don't send dhcpdiscover just dhcprequest with the
dinamic ip, than the dhcp server give ip from static pool even if there
is a lease in leases file or delete the lease which mac address has a
fixed address in dhcpd.conf at dhcpd reload/restart?

Thanks
