6.2 DHCP Server (Advanced Mode only)
DHCP stands for Dynamic Host Configuration Protocol. The built-in DHCP server automatically assigns IP addresses to
the computers and other devices on each local area network (LAN). In this section you can view a list of assigned IP
addresses and reserve IP addresses for particular devices.
Active Leases: A list of devices that have
been provided DHCP leases. The DHCP
server automatically assigns these leases.
This list will not include any devices that
have static IP addresses on the network.
Reservations: This option lets you reserve
IP addresses; you can 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 router. The 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 a reservation.
While you have the option to manually input the information to reserve an IP address (Hostname, Hardware Addr, IP
Addr), it is much simpler to select a device under the Active Leases
section and click ―Reserve.‖ The selected device‘s
information will automatically be added under Reservations.
