4.4 DDNS
The Dynamic Domain Name System (DDNS) update integrates DNS with DHCP. The two protocols are
complementary: DHCP centralizes and automates IP address allocation; DDNS update automatically
records the association between assigned addresses and hostnames at pre-defined intervals.
The DDNS allows frequently changing address-hostname associations to be updated frequently. Mobile
hosts, for example, can then move freely on a network without user or administrator intervention. DDNS
provides the necessary dynamic update and synchronization of the name-to-address mapping and
address-to-name mapping on the DNS server.
Before enabling DDNS, go to the System Ports tab to configure the DNS Server and Default Gateway
parameters and ensure that the NVR connects to the Internet.
To enable DDNS:
1. Choose Main Menu > Network > DDNS > Enable DDNS .
2. Configure parameters displayed.
