3. Select your Domain Name Servers (DNS). Domain name servers (DNS) convert Internet
names such as www.google.com, www.netgear.com, etc. to Internet addresses called IP
addresses.
– Select the Get Automatically from ISP radio box if you have not been assigned a static
DNS IP address.
– If the Use these DNS Servers radio box is selected, enter valid DNS server IP addresses
in the Primary DNS Server and Secondary DNS Server fields.
4. Click Apply to save your settings. Click Tes t to verify that the connection is active.
Configuring Dynamic DNS (If Needed)If your network has a permanently assigned (static or fixed) IP address, you can register a domain
name and have that name linked with your IP address by public Domain Name Servers (DNS).
However, if your Internet account uses a dynamically assigned IP address, you will not know in
advance what your IP address will be, and the address can change frequently. In this case, you can
use a commercial dynamic DNS service, which allows you to register an extension to its domain,
and resolves DNS requests for the resulting FQDN to your frequently-changing IP address.
For rollover mode, you will need a fully qualified domain name (FQDN) to implement features
such as exposed hosts and virtual private networks regardless of whether you have a fixed or
dynamic IP address.
Note: At this point in the configuration process, you should now be connected to the
Internet.
Note: If your ISP assigns a private WAN IP address such as 192.168.x.x or 10.x.x.x, the
dynamic DNS service will not work because private addresses will not be routed
on the Internet.
