3.1.4 BASIC - DHCP
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).

DHCP SETTINGS
Enable DHCP Server:
Once your Wireless 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 values (from and to) define a range of 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 (see Static DHCP Client below), so that the
DHCP Server knows that this specific address can only be used by a specific computer or device.
Your Wireless router, by default, has a static IP address of 192.168.0.1. This means that addresses
192.168.0.2 to 192.168.0.254 (from 2 to 254) can be made available for allocation by the DHCP Server.
