UDR-204(C) Operation manual Revision 3.0
Under DHCP or PPPoE configuration using IP Router, the DVR will receive an IP address
periodically, and each time, the IP address can be different. Therefore, in order for users to
access the DVR over the network, it must update its IP address to the DDNS Server.
Under IP router configuration, IP of DVR must be setup as static IP address and it must
update its IP address to the DDNS server. Therefore DDNS Link on NETWORK SETUP
menu should be on. (When IP router is connected from static IP, it is no necessary to setup
DDNS link on)
By indicating the address of a DDNS Server, the UDR-204 will update its IP address and its
MAC address periodically. Therefore, when users access the DVR over the network, the
same URL can be used. For example, if the DVR has a MAC address of
“00:09:F8:12:34:56” and the domain name of the DDNS server is “ns.udrdns.net ”, the users
can access the DVR with the URL “u123456.udrdns.net” The DDNS will know which
machine to resolve the URL because it would contain an updated IP address and MAC
address list.
The factory default value of the DDNS server address from UNIOM Technology Co, Ltd. is as
follows:
DDNS address: 211.104.85.235
DDNS connection port: 7100
If users wish to operate the DDNS server by themselves, please contact us.
