    Dynamic DNS (basic questions)

    Dynamic DNS (basic questions) 19th Mar 17 at 10:06 PM
    I have a friend with a domestic CCTV system. He's just changed ISP and got a new router and asked for help as he couldn't access any cameras.

    I got everything working over the LAN, but he can't access the cameras over the internet.

    It seems he was using some kind of Samsung DDNS service previously (he has the details). I looked in the router settings, but there are only three DDNS providers you can select -- none of them Samsung, and they only appear to offer paid services. My friend reckons the Samsung DDNS service was free.

    The host name he has is (Where "something" is an alphanumeric string.)

    The only service providers listed in the router settings are:

    I've never used DDNS before, so I'm not really sure how to set it up.

    Can anyone help?

    I imagine his cameras are samsung cameras and the old DNS was part of the samsung camera software.

    Depending on his ISP, his IP address (even if dynamic) is likely pretty static in reality (unless he does silly things like turning his router off at night). You might not even need dynamic dns.

    I've had the same IP on plusnet for about 3 years. Same with my Virgin Media connection.

    Hopefully this post doesn't get deleted.
    I use no-ip on my Netgear DG834GT router, if you look hard enough, there is a free option, but you have to login every 30 days to keep the account alive.
    They email you a few days in advance as a warning.
    Only takes seconds to login and solve the catchpa.

    I've moved over to DuckDNS ( from No-IP.
    It's the same sort of thing, no frills and free with none of this 30 day activation

    Oh yeah -- I think I saw that, but... my friend isn't exactly "hands on" when it comes to computers. There's no way he'll remember (or be bothered) to login regularly.

    I've pretty much given up. He's not sure what the DDNS settings are, and... doesn't seem that bothered about fixing it for now. So there's not much more I can do :-/

    Thanks again, everyone. I think I understand DDNS and CCTV systems a little bit better, at least.
