NBG-416N User’s Guide

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 NBG-416N, 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 
NBG-416N 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 
NBG-416N unless you are instructed to do otherwise.

Use DNS (Domain Name System) to map a domain name to its corresponding IP 
address and vice versa, for instance, the IP address of www.zyxel.com is 
204.217.0.2. The DNS server is extremely important because without it, you must 
know the IP address of a computer before you can access it. 

The NBG-416N can get the DNS server addresses in the following ways.

The ISP tells you the DNS server addresses, usually in the form of an information 
sheet, when you sign up. If your ISP gives you DNS server addresses, enter them 
in the DNS Server fields in the Wizard and/or WAN > Internet Connection 
screen.

If the ISP did not give you DNS server information, leave the DNS Server fields 
set to 0.0.0.0 in the Wizard screen and/or set to From ISP in the WAN > 
Internet Connection screen for the ISP to dynamically assign the DNS server IP 
addresses.
