So when I set out to "play around", I looked at these projects and tried to modify them. Fortunately for them, but unfortunately for beginners, these are already quite far developed and complex projects. So impatient me set out to "quickly write something in Python". Almost two weekends later, I put in so much time that I thought I might as well share this for others to explore (and hopefully enjoy). I tried keeping things simple and without external dependencies. In the end it was a good experience but became much bigger than I intended.
So I hope you enjoy: https://github.com/vvm2/shiddns
