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?
Cloudflare, Porkbun, Namecheap and many other registrars offer dynamic DNS via API or a ddns client very easy to setup.
