Dynamic Dns - D-Link DSL-G604T User Manual

To configure the DNS for the Router, use the DNS Relay Selection pull down menu to select the DNS
configuration for the router. There are three choices:

Disable DNS – Selecting this option will disable the DNS function of your router.

Use Auto Discovered DNS Server Only – This choice will enable the router to automatically
find the DNS Server for your setup.

Use User Discovered DNS Server Only – This choice will enable the DNS Servers entered in
the Preferred DNS Server and Alternate DNS Server fields. These two IP addresses must be stated
to you by your ISP.
The router will first try the Preferred DNS Server to resolve a website's URL IP address. If that IP
address fails to resolve the URL, the Router will then try the Alternate DNS Server. Your ISP must
provide this information to you. Click Apply to set the DNS configurations into the memory of the
Router.

Dynamic DNS

The Router supports DDNS, a service that maps Internet domain names to IP addresses. DDNS serves
a similar purpose to DNS in that DDNS allows anyone hosting a Web or FTP server to advertise a
public name to prospective users. Unlike DNS that only works with static IP addresses, DDNS works
with dynamic IP addresses, such as those assigned by an ISP or other DHCP server. DDNS is popular
with home networkers, who typically receive dynamic, frequently-changing IP addresses from their
service provider. To use DDNS, one simply signs up with a provider and installs network software on
their host to monitor its IP address. Please see your ISP for further information.
