For a long time, I needed a simple and minimalistic tool showing a quick overview of my domain names configuration and statistics. I originally planned to implement it as a shellscript, but Node makes it so easy to write efficient CLI tools and distribute them via npm so it made more sense to go this way. The tool performs asynchronous DNS requests and as a bonus, displays a nice colored Unicode table, thanks to the great cli-tables module.
Here is the output of running dnc with two domains in the configuration file:
To install, simply invoke:
npm install -g dnc
