Click Apply to save the settings.
3.3.11 Dynamic DNS
The device supports dynamic domain name service (DDNS). The dynamic DNS service allows a dynamic
public IP address to be associated with a static host name in any of the many domains, and allows access to
a specified host from various locations on the Internet. Click a hyperlinked URL in the form of
hostname.dyndns.org and allow remote access to a host. Many ISPs assign public IP addresses using DHCP,
so locating a specific host on the LAN using the standard DNS is difficult. For example, if you are running a
public web server or VPN server on your LAN, DDNS ensures that the host can be located from the Internet
even if the public IP address changes. DDNS requires that an account be set up with one of the supported
DDNS service providers (DyndDNS.org or dlinkddns.com).
Choose Advanced > Dynamic DNS. The page shown in the following figure appears.
