Set up umbrella domain

As of now, we specify all domains that should change in cloudflare. This can be complicated and won't work across different cloudflare accounts without increasing complexity.

A better way would be to have a domain, say "myserver.example.com", be the only domain I update with the new IP. All domains that should point to my server should have CNAME records to "myserver.example.com".

Power Outage Mechanism

Everything in this app lives in memory, so in case of power outage the service looses all its data. If ISP distributes a new IP to my router at this point, which it often does, then service won't know it has changed.

Simple solution is to store current IP as a file. This way we can save the state of the service and know if the IP has changed during power outage.
