6.1.2 DDNS Server
DNS, which stands for “Dynamic DNS”, is a method, protocol, or network service that provides the
capability for a networked device, such as a router or computer system (in this case, the NVR) using the
Internet Protocol Suite to notify a domain name server of changing in real time the active DNS
configuration of its configured host names, addresses or other information stored in DNS.
A popular application of dynamic DNS is to provide a residential user’s Internet gateway that has a
variable, often changing, IP address with a well-known host name resolvable through standard DNS
queries.
This is useful if the NVR is placed on the Internet with a dynamic public IP, in which once the DDNS is
properly set up, users can access the NVR remotely with the DDNS domain name without worrying if the
IP has changed or not.
*Please make sure a valid DNS server has been configured under the “Network Setting” page to enable
this function to work properly.
*The NVR currently works with DDNS service provided by “PLANET DDNS” and “DynDNS”. For more
information, please go to
www.planetddns.com and www.dyndns.com
*If the NVR is placed behind a router or Internet gateway, please make sure port forwarding for port 80
is configured on the router or the gateway in order for the DDNS function to properly register with the
service. It’s often suggested to use the DDNS function in the router / gateway for such case instead.
*Once you have the DDNS function successfully up and running, please DO NOT forget to configure
port forwarding for the NVR Web port (default 80) and the streaming port (default 9877) in the
router/gateway for remote viewing. You can then type in http://yourddnsdomain in the browser to access
the NVR remotely for live viewing.
1. In order to properly configure the DDNS service function, please register a free DDNS domain name
and account from PLANET DDNS first. Go to http://www.planetddns.com from the browser to do so.
