Lease Time: The length of time for the IP address lease.
Configuring a proper lease time improves the efficiency for the
DHCP server to reclaim disused IP addresses.
For example: If the lease time is set to one hour, then the DHCP
server will reclaim disused IP addresses every hour.
9.2 DHCP Client List &Reservation
DHCP Client List displays information of devices that have
obtained IP addresses from the device's DHCP Server. If you would
like some devices on your network to always have the same IP
addresses, you can use this feature and manually add a static DHCP
Reservation entry for each such device. And then a registered MAC
will get a correspondingly reserved IP address while an
unregistered MAC will be assigned with an unused IP address.
Host name: Displays name of a given host (DHCP client). IP
Address: Enter the IP address for static DHCP reservation.
MAC Address: Enter the MAC address of a computer to
always receive the same IP address (the IP you just specified).
