View and manage current DHCP leases
The DHCP server maintains a current list of its leases, reservations and unavailable
addresses. The displayed lease list may contain entries that report a variety of status
descriptions. The Lease Status types are identified and described below.
Even after a lease has expired or is released by a DHCP client, the associated IP address is
not immediately returned to the available address pool. Rather, there is a non-configurable
grace period during which the lease record is retained by the DHCP server. At the end of
that grace period, the lease record is automatically deleted and the associated IP address is
returned to the available address pool. Where a grace period is observed, this is indicated
in the Lease Status descriptions below.
The grace period is incorporated in the DHCP server to increase the consistency of
offering the same IP address to a DHCP client, even if that client is rebooted or off the
network for a period of time that does not exceed the grace period.
You can explicitly remove leases from the DHCP server while it is running. To remove a
lease, select the checkbox to the left of the lease information in the table of leases, then
click the Remove button below the lease table. To remove all leases, select the checkbox
to the left of the descriptive headings at the top of the table, then click the Remove button
below the lease table.
Note
Removing a lease will cause the associated IP address to be returned
immediately to the available address pool. Any IP address in this available
address pool may be served in a new lease to a DHCP client.
Static lease reservations will always show in the lease list. These reservation
leases may be removed, but a new lease will be created immediately. To disable
or permanently remove a reservation, use the DHCP server Settings page in the
Network Configuration area.
