LAN and WAN IP Addresses

The LAN parameters of the NBG6616 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), read the embedded Web Configurator help regarding what fields need to be 
configured.

The NBG6616 is pre-configured with a pool of 32 IP addresses starting from 192.168.1.33 to 
192.168.1.64. This configuration leaves 31 IP addresses (excluding the NBG6616 itself) in the 
lower range (192.168.1.2 to 192.168.1.32) for other server computers, for instance, servers for 
mail, FTP, TFTP, web, etc., that you may have.

The NBG6616 has built-in DHCP server capability that assigns IP addresses and DNS servers to 
systems that support DHCP client capability.

IP alias allows you to partition a physical network into different logical networks over the same 
Ethernet interface. The NBG6616 supports three logical LAN interfaces via its single physical 
Ethernet interface with the NBG6616 itself as the gateway for each LAN network.
