Configuring DDNS
ZXHN H108N supports the DDNS function. This procedure introduces how to configure DDNS to
enable the host that has a dynamic IP address to provide the domain name service.
Prerequisite
Before configuring DDNS, make sure that:
The inbound connection is enabled.
The domain name has been registered.
Context
DNS is the way in which a URL or domain is converted to an IP address. In many home networking
environments, the DSL IP address is provided by DHCP and therefore changes from time to time.
Dynamic DNS (DDNS) allows you to have a website such as www.my-site.com in which the IP address
is dynamically assigned.
After DDNS is applied, the device that has the dynamic IP address can also provide the domain name
service. For example, when the device obtains an IP address through xDSL dial-up or DHCP server
dynamic allocation, the device provides the domain name service. If the device IP address changes,
it does not affect the subscriber’s access to the host by using the domain name.
Steps
1.
On the navigation tree, click [Application→ DDNS]. The DDNS configuration page is displayed,
see Figure 42.
Figure 42 DDNS
