Specify the IP Addresses That the Modem Router Assigns
By default, the modem router acts as a Dynamic Host Configuration Protocol (DHCP) server. 
The modem router assigns IP, DNS server, and default gateway addresses to all computers  connected to the LAN. The assigned default gateway address is the LAN address of the 
modem router. 
These addresses must be part of the same IP address subnet as the 
 modem router’s LAN IP 
address. Using the default addressing scheme, define a range between 192.168.0.2 and 
192.168.0.254, although you can save part of the range for devices with fixed addresses.
