move your domain(s) to porkbun, but setup cloudflare's nameservers on your domain. then you can manage your records and setup ddns through cloudflare.

For those of you that use DDNS for essentially homelab (say to allow friends and family to watch media on your self hosted Plex Media Server) - just use TailScale.

I would think about actual publicly know IP address (like it is for dynamic DNS) only for things like hosting your own mail server.
