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?
My router actually has a UPnP API that I can request and get my external IP, which I like so I can poll it every few seconds and not worry about rate limiting or something.
