IP addresses are easy to use in the configurations that inspired mrsk. Small apps that are fairly static. There are two main problems that mrsk is trying to solve.
1. Moving our stuff out of the cloud without going back to static hosts.
2. Giving new rails devs a tool where they can deploy their application easily, in a modern fashion.
Both of these are not so large or complex that you must use hostnames in configs instead of IP addresses. I will note, that most of our internal configs, do in fact, use hostnames rather than IP's. But judging a tool because an example used an IP address seems shortsighted.
There are plenty of things in mrsk to discuss without fixating on that.
