Once you have decided on the network number, pick an IP address that is easy to 
remember, for instance, 192.168.1.1, for your WiMAX Modem, but make sure that 
no other device on your network is using that IP address.
The subnet mask specifies the network number portion of an IP address. Your 
WiMAX Modem will compute the subnet mask automatically based on the IP 
address that you entered. You don't need to change the subnet mask computed 
by the WiMAX Modem unless you are instructed to do otherwise.
7.6.2  DHCP Setup
DHCP (Dynamic Host Configuration Protocol, RFC 2131 and RFC 2132) allows 
individual clients to obtain TCP/IP configuration at start-up from a server. You can 
configure the WiMAX Modem as a DHCP server or disable it. When configured as a 
server, the WiMAX Modem provides the TCP/IP configuration for the clients. If 
DHCP service is disabled, you must have another DHCP server on your LAN, or 
else each computer must be manually configured.
The WiMAX Modem is pre-configured with a pool of IP addresses for the DHCP 
clients (DHCP Pool). See the product specifications in the appendices. Do not 
assign static IP addresses from the DHCP pool to your LAN computers.
These parameters should work for the majority of installations. If your ISP gives 
you explicit DNS server address(es), see 
.
7.6.3  LAN TCP/IP
The WiMAX Modem has built-in DHCP server capability that assigns IP addresses 
and DNS servers to systems that support DHCP client capability.
The LAN parameters of the WiMAX Modem are preset in the factory with the 
following values:
• IP address of 192.168.1.1 with subnet mask of 255.255.255.0 (24 bits)
• DHCP server enabled with 32 client IP addresses starting from 192.168.1.33. 
These parameters should work for the majority of installations. If your ISP gives 
you explicit DNS server address(es), see 
.
