DHCP-server / gaps

Hi,

we have a few DHCP-server running. A typical range is from X.X.X.21 to X.X.X.220 which results in 200 useable dhcp-addresses.

Mikrotik starts always from .220 with the first lease. If this device (with the .220) is removed from the subnet and the lease is gone as well, the next device gets .219. This behaviour creats gaps in the dhcp-range. It seems there is a database in which is stored that .220 was once used.

Is there a way to reset this that always a new device gets .220 (unless there is an active lease)?
