My ISP does not give me a static IP. It doesn’t change often, but in the rare case that it has changed I never discover it before I actually need it.
So. I wanted a very simple way of auto-updating the
home.example.com record. I didn’t want to bother with a thirdparty client from something like dyndns (and I didn’t want to pay for anything).
As I use Cloudflare as dns service for all domains I own I could just use their API and solve it with a oneliner, but doing it with Ansible is more readable...
