DNSControl: Version control your DNS configuration
I am now versioning my DNS configuration. With the tool DNSControl it is possible for a number of DNS providers and registrars to manage the DNS and name server settings of your own domains. For example, it is possible to configure several DNS services at the same time (for example as backup DNS) or to make major changes by making a small code change and deploy them through continuous integration. In my configuration I even let JavaScript code generate part of the configuration. A great tool, I think!
