192.168.1.254 (zero and 255 are reserved). In other words, the first three numbers specify the
network number while the last number identifies an individual computer on that network.
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-417N, 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-417N 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-417N unless you are instructed to do otherwise.

3.4.7 DNS Server Address Assignment

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-417N 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
1
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
2
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.
