4.2 Access the ZyXEL Device Using DDNS
If you connect your ZyXEL Device to the Internet and it uses a dynamic WAN IP
address, it is inconvenient for you to manage the device from the Internet. The
ZyXEL Device’s WAN IP address changes dynamically. Dynamic DNS (DDNS)
allows you to access the ZyXEL Device using a domain name.
To use this feature, you have to apply for DDNS service at www.dyndns.org.
This tutorial shows you how to:
• Registering a DDNS Account on www.dyndns.org
• Configuring DDNS on Your ZyXEL Device
• Testing the DDNS Setting
Note: If you have a private WAN IP address, then you cannot use DDNS.
