How exactly do is use ipv6 to reach my Jellyfin Server (alien.top)

I recently got a small pc for my Jellyfin Server.

Ideally, I want to reach it from everywhere, but alas, I got no static Ipv4 Address with which I am more familiar.

Can I just expose my Ipv6 Address through that damned Vodafone and use the IP Address together with the Port, or do I need an DNS with AAAA record?
And are there any pitfalls I need to take care of?

I am definitely not the most experienced Dude when it comes to these things, so I would appreciate it if you could hold my hand here a little bit :)

Sorry for breaking this into two posts. My employer insists on my working when I’m on the clock for some obscure reason. :-)

My guess is that what happens when IPv6 packets hit your home network depends on how your ISP decided to hand out addresses. If they gave you a single IPv6 address for your account, the there is absolutely no change from how IPv4 works, it’s just using different symbols. As usual you’ll need to forward the correct port to your Jellyfin or reverse proxy.

If they’ve given you a range of IP6 addresses, I suspect there would be some sort of “drop all inbound” firewall at your gateway/router” that you would have to modify. Either way you will need to dig into your modem settings or call your ISP for “help”.

Like I said in the other comment, I haven’t played with v6 much, but I hope these posts help you some.
