Scroll to the following screen in the "DHCP and DNS" window.
This screen displays the lease information to which DHCP
server assigns automatically, including Hostname, IP address,
MAC address (or DUID), and Remaining Lease-time (DUID
stands for the DHCP Unique Identifier). Please look at the
frame in red above.
The next category that users can scroll to is "Static Leases" as
follows.
Static leases are used to assign fixed IP addresses and symbolic
hostnames to DHCP clients by calculating MAC-Address. They
are also required for non-dynamic interface configurations
where only hosts with a corresponding lease are served.
Add: Add a new lease entry.
After clicking the "Add" button, a new entry with 4 blank
input boxes will appear. Allow users to fill in the information
such as the MAC-Address (identifies the host), the IPv4-
Address (specifies the fixed address to use) and the
Hostname (is assigned as symbolic name to the requesting
host).
