Primary IP Address: Private IP address is used for the purpose of system management. When it is assigned, PC on
the LAN is able to use the specified address to access this ADSL Router through Ethernet.
By default, the IP address and subnet mask is 192.168.100.100 and 255.255.255.0 respectively.
This will give you an available range of IP addresses from 192.168.100.2 to 192.168.100.254
that can be assigned to PCs on the LAN.
Secondary IP Address: If you applied for multiple IP address from your ISP, you will have a range of IP address for
the ADSL Router and other network devices on the LAN. You can fill in the IP address
assigned by ISP in the public IP address field.
DHCP Server
This page allows you to enable DHCP server on LAN interface and then your router can assign IP addresses to those
PCs connected to your router.
The ADSL Router implements a built-in DHCP (Dynamic Host Configuration Protocol) server, which dynamically
assigns IP addresses and DNS server to the PCs on the LAN. DHCP function spares you the hassle of manually
assigning a fixed IP address to each PC on the LAN. It is probably you already have a DHCP server on your network
and you do not enable this function. By default the DHCP Server is enabled on private LAN interface
(192.168.100.0).
Choose the Enabled radio button and click Configure to get advanced settings. Enter the requiring information and
click Apply to invoke the configurations that you set. Below is the web page for setting DHCP server.
