So I dont have to install the no-ip dynamic update client on my dvr? I tried pinging the DDNS provider and everything seems to be working ok until the router rebouts. On the dashboard of my DDNS account it shows my old ipv4 adress near my hostname but it does not update from the dvr nomatter how long I wait. I dont stay at the building where the dvr and cameras are installed very much, would that be a problem since I am logging into the DDNS service from a different internet connection? Also do I have to configure the DDNS for my router, I logged into my router and it said I could do something with hostnames I just have to change the default setting for the device which is Wlan to a set static ip but there is no other option exept Wlan. I am very new to networking so I probably didnt make any sense or misused alot of networking terms
If you've configured the DVR with the login credentials for your DDNS, there isn't a need for additional software.
If the DVR is somehow causing issues, you may want to look into configuring the router instead. Most routers support the popular DDNS services. I personally prefer to use the router's built in client, and it hasn't ever failed to work properly. If you do decide to configure the service on your router, you should disable it on the DVR. Having more than one client configured for DDNS may cause problems with your provider.
In addition, it's considered best practice to set a static private IP address for your DVR that is outside the range of the router's LAN DHCP. This internal IP address does not affect DDNS, and keeps any dynamic IP changes in the LAN from disrupting DVR service.
