DHCP SERVER
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. Select a device
and click
Reserve to add the device and its IP
address to the list of Reservations .
Reservations : This is a list of devices with
reserved IP addresses. This reservation 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 .
