I won't list out the pros and cons of using DDNS here, however, I find it useful for certain use cases. If you are already using DigitalOcean to manage domain records, it is possible to use their domain record API to do DDNS.

Application

I've implemented a C# application to do this. The source code is here.

Configuration Requirements

Configuration requirements are documented here.

Deploying with Docker

I deployed this with Docker so notes on how to do so are here.
