1.
After the setting is successful, the device will assign the preset IP address for the specified
computer in a fixed way.
2.
The assigned IP addresses must be within the range provided by the DHCP server.

DHCP auto binding
Below is the description of DHCP automatic binding function.
Enable DHCP automatic binding: When DHCP automatic binding is enabled, the device will
scan the Intranet, and bind IP/MAC of intranet users who obtain an IP address dynamically,
and the device will bind any one IP address it assigns subsequently with the MAC address of
the client. Enabling this function can protect against network ARP spoofing. If it is not
enabled, no automatic binding operation is to be done.
Enable DHCP automatic deletion: When DHCP automatic deletion is enabled, it means that
the device will automatically delete the IP/MAC previously bound automatically after the
lease expires or the user releases the address actively; if it is not enabled, it means that no
automatic deleting operation is to be done.
6.4.4
DHCP client list
For the IP address already assigned to the network computer, its information can be viewed in the
DHCP client list. Information as shown in the figure below: The DHCP server assigns the IP
address of 192.168.1.100 in the address pool to the network computers whose MAC address is
6C:62:6D:E9:6D:13, and the rest of the time for the computer to lease this IP address is 86333
seconds.
