Own domain for Jellyfin and privacy concerns (lemmy.world)

Hi everyone,

a couple of friends and I have a Jellyfin server running which is exposed to the internet via a reverse-proxy and https by using a free dynDNS provider.

The setup is working fine besides the dynDNS provider. We constantly face connection issues, making the dynamic DNS functionality very unreliable.

So I started looking into possible solutions and one particular would be to buy an own domain which would only cost a few bucks each month. With this I could keep the current setup and would just need to change the domain (and possibly the SSL certificate). I found a provider over which I could buy (rent?) a domain and which also provides dynDNS functionality. But I am not too sure if I understood this correctly:

  • if I have an own domain, why would I need the additional dynDNS functionality? I would guess that I would just continue updating your server's IP address to the domain name like we are doing now
  • can the provider over which I rent the domain with servers in my country actually see what our traffic is? Especially since we are streaming our movies etc.
  • is there a better way of obtaining and setting up your own domain also in terms of privacy and reliability than with a bigger company offering such services?

Thanks a lot for your feedback!

Edit: An important fact I forgot to add in my main post is that during these issues, the general server connection should be fine since it is located at a friends house and his internet connection is unaffected (e.g. we could still talk in Discord normally and he had no internet issues whatsoever)

Can you explain the connection issues? Dynamic dns services aren’t much different than a normal domain name.

If the problem is with your ip address changing then you need to get a more permanent ip.

In fact you can usually get a domain name from the dynamic dns provider and they can update it.

A way around this is to use a service like Tailscale. Their ip address for your host won’t change. The downside is you need to be on von to access it. There might be other options.

The server is running at my friends house who has a fiber connection. When we face these connection issues, it does not necessarily mean that all of us cannot access Jellyfin but often times only a couple of us cannot access (same error as if you mistype a web-address, so it cannot resolve the domain name). During these periods of connection issues, the internet connection of my friend is working completely fine. I have a script running that constantly sends the current IP address to the dynDNS provider. I also looked into how often our ISP changes the IP address and it is not very often and not during these issues.

A different domain name won’t fix the issue you’re describing.
