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.
Meanwhile, my ISP would often rotate their customer behind their CGNAT, so the IP address from the routers upnp would often return 10.x.x.x . One of the main reason I gave up using dynamic DNS and use Tailscale instead.
Port forwarding wouldn’t work anyway with CGNAT, so I don’t think that’s much of an issue.
