Section 3 - Software Configuration
Add/Edit DHCP Reservation
This option lets you reserve IP addresses, and assign the same IP address to the network device with the specified MAC address any time it requests
an IP address. This is almost the same as when a device has a static IP address except that the device must still request an IP address from the D-Link
router. The D-Link router will provide the device the same IP address every time. DHCP Reservations are helpful for server computers on the local
network that are hosting applications such as Web and FTP. Servers on your network should either use a static IP address or use this option.
The following parameters will be available for configuration:
Enable: Check this box to enable the reservation.
Computer Name: Enter the computer name. Alternatively, select a
computer that currently has a DHCP lease from
the drop down menu and click << to automatically
populate the Computer Name, IP Address, and
MAC Address fields.
IP Address: Enter the IP address you want to assign to the
computer or device. This IP Address must be
within the DHCP IP Address Range.
MAC Address:
Enter the MAC address of the computer or device.
