Do you know if they support dynamic DNS? I self host most of my stuff and I have a dynamic IP at home

Yes, in that they have an API for their DNS service. It's supported by ddns-updater.

		Really wish they would allow creating limited scope API keys though. You can only limit keys by domain, not by action or record which would be ideal.
