A dynamic DNS system for DigitalOcean

The DigitalOcean API allows domain name records to be updated. This means that it is possible for DigitalOcean DNS records to be used as a dynamic DNS system. Existing clients seem to query third-party services like http://ifconfig.me/ip. Rather than relying on these services, I wanted to use my own DigitalOcean droplet to serve the IPs.

doddns is composed of a client and server, which run on the local machine and a remote server respectively. The server is meant to run on a DigitalOcean droplet. It responds to HTTP requests with the IP address of the client a la http://ifconfig.me/ip. The client updates the DNS record for the given domain and subdomain with this address automatically.
