how can I know how many IPs in a subnet have been assigned? by looking at the dhcpd.leases file? do I need to look at the dhcpd.leases~ file? when an assigned IP is released by the client, will dhcpd delete the entry in the dhcpd.lease file? I mean if I can conclude that an IP is available if the IP can not be found in the dhcp.leases file. Luc
