You could maintain two config files with pools that do not overlap
but are within the same subnet. Then you could cron a dhcpd restart
that alternates the config files every 24 hours.

Hi dhcp users,
we are running a DHCP Server for about 10k customers with a single isc dhcpd (4.2.4p2) process running.
Our customers do almost ever get the same IP Address assigned when sending DHCPDISCOVER.
Lease time is 1200 sec. (20 minutes), pool is 95-97% in use all day. Even after 10h offline,
dhcpd will answer an DHCPDISCOVER with an DHCPOFFER for the same ip address as assigned 10h earlier.
Some of our customers would like their ip address to change from time to time (e.g. every 24h)
as they where used to when using PPP.
Is there any way to accomplish this using isc dhcpd?
