Configuring a proper lease time can improve the
efficiency for DHCP server to reclaims the invalid IP
addresses.
For example:
If the lease time is an hour, then DHCP server will reclaim
the IP address every hour.
7.2 DHCP List and Binding
DHCP client list displays computers' IP address, MAC
address, host name and other information which are
assigned by the DHCP sever. You can manually enter the IP
and MAC address and convert it to static allocation.
According to the connected computer's MAC address, DHCP
will assign the appropriate IP address. If you can not find the
corresponding static binding entry, assign an IP from the
DHCP pool to the computer. If the computer had been bound
for the IP address and MAC and they do not correspond,
then the computer will be unable to access Internet via the
equipment. (Binding it prevents the client changing IP
address and to evade the monitoring device)
