IP Address
The IP address of the this device on the local area network. Assign any unused IP address in
the range of IP addresses available for the LAN.
Subnet Mask
The subnet mask of the local area network.
DHCP Server Settings
DHCP stands for Dynamic Host Configuration Protocol. The DHCP section is where you
configure the built-in DHCP Server to assign IP addresses to the computers and other devices
on your local area network (LAN).
Enable DHCP Server
Once your router is properly configured and this option is enabled, the DHCP Server will
manage the IP addresses and other network configuration information for computers and other
devices connected to your Local Area Network. There is no need for you to do this yourself.
The computers (and other devices) connected to your LAN also need to have their TCP/IP
configuration set to "DHCP" or "Obtain an IP address automatically". When you set
Enable
DHCP Server , the following options are displayed.
DHCP IP Address Range
These two IP values (Start and End) define a range of IP addresses that the DHCP Server
uses when assigning addresses to computers and devices on your Local Area Network. Any
addresses that are outside of this range are not managed by the DHCP Server; these could,
therefore, be used for manually configured devices or devices that cannot use DHCP to obtain
network address details automatically.
It is possible for a computer or device that is manually configured to have an address that does
reside within this range. In this case the address should be reserved, so that the DHCP Server
knows that this specific address can only be used by a specific computer or device.
Your router, by default, has a static IP address of 192.168.10.1. This means that addresses
192.168.10.2 to 192.168.10.254 can be made available for allocation by the DHCP Server.
Subnet Mask
The subnet mask of the local area network.
Gateway
The IP address of the router on the local area network. For example, 192.168.10.1.
DHCP Lease Time
The amount of time that a computer may have an IP address before it is required to renew the
lease. The lease functions just as a lease on an apartment would. The initial lease designates
the amount of time before the lease expires. If the tenant wishes to retain the address when
the lease is expired then a new lease is established. If the lease expires and the address is no
longer needed than another tenant may use the address.
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 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 use this option.
Computer Name
You can assign a name for each computer that is given a reserved IP address. This may help
you keep track of which computers are assigned this way. Example:
Game Server .
IP Address:
The LAN address that you want to reserve.
