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?
I think using the cloudflare API is the way to go. You could probably set up an internal service that translates your home router’s dyndns request to a cloudflare API call.
Only if you had root access to your router. It’s a lot easier to write or find a very simple update script and schedule it to run every now and then via crontab.
The daemon script is simpler, true. but usually you can just point your router at some dyndns URL and you could put an internal IP for that.
