Oh yeah, I forgot to mention.

One of the motivators for #Duppy, was off-the-shelf compatibility with #letsencrypt and #certbot - certbot ships with an #rfc2163 plugin.

So if you are hosting domains for people in a database and want them to be able to easily use DNS validation to obtain certs... this makes that possible without custom software on the user's side.

Somehow, 3 gigs in a row, I've found myself involved with dynamic #DNS infrastructure.

The pattern is always the same; there is a database of some sort, and then #bind or #powerdns serving results. Updates happen using a custom web interface or home-brewed web API.

But - we have a standard for dynamic DNS updates! It's called #rfc2163. Why aren't we using it? Because DNS is less dev friendly, I guess?

So I wrote Duppy: https://github.com/pagekite/duppy - a reusable #RFC2163 DNS update server.
