Information regarding the usage of the dynamic pool on each subnet is gathered periodically from the DHCP server. The information displayed will typically be no more than a few minutes old.
Current usage will be displayed in terms of the number of available addresses out of the total number in the dynamic pool. Hosts with static IP addresses do not affect the count. Maximum and minimum usage is displayed from the previous Sunday onwards, i.e. a period of between seven and fourteen days.
Dynamic pool information is also provided through the DHCP server log search interface, however you need to click on View dynamics pool information button once you have selected your subnet and entered your password.
