in the past when I've had to use DDNS services they are provided by DVR/NVR manufacturer. Ones I've used in the past are Samsung and Hik.
they've always worked perfectly and to this day they are still connected. I assume the external IP is changing on a regular basis but the DDNS service automatically updates it.
i am testing a tp link nano router at home in order to create a hardwired Ethernet connection at my alarm panel, wirelessly from my EE router.
worked a treat but the other day could not connect. my external ip had changed but no-ip had not automatically updated it. am I missing something here?
or is this a limitation of free DDNS services?
