3.3.9 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).
