Real domain with dynamic IP (lemmy.world)

I got a homelab, at the moment I am only running some local stuff and tailscale to reach my stuff remotely.

I can use tailscales ddns, but I would like a real domain. Is there a domain registrator that works with dynamic ips? Or do I need to use a CNAME instead of A record?

Does your ISP support IPv6?

[–] [email protected] 3 points 1 year ago

Silly as it is, many ISPs hand out dynamic IPv6 prefixes that may change once in a while. Or "dynamic" prefixes that never seem to change (but are not guaranteed never to change).

The reason is of course that they like being able to charge extra for static IPv4 addresses, and they see no reason to get rid of that revenue source for IPv6.

I think I can ask them about it. Never really used ipv6. Maybe that's even better. Then I can maybe use more than one IP even. I don't know how the ISPs deal with it. Do I only get one for my router, or can I get a bunch of them.. hmm

with IPv6 you are able to address your internal network devices directly without port forwarding. Just make sure your router and other gear support it so you have everything you need.

This is the way.

Yea, my stuff supports it. But I never checked out how the ISPs is dealing with it. I will check it out!

If you have a static IPv6 address you can host your own authoritative DNS locally and use it for IPv4.
