I needed a Dynamic DNS service for a couple of devices I had in my DMZ, but most free services requires you to confirm the hostname manually regularly, or include some kind of restriction.
I use Cloudflare for some domains, and I dug in their APIs to make my own DDNS.
It should be easily to adapt it to fit other DNS APIs, feel free to contribute!
