Setup

First, be sure you're collecting the email address in the form:

Digital Ocean recently released private networking support in their NYC2 Data center.

They also published a blog post on how to setup a new droplet with private networking. But one thing the post doesn't do is tell you how to scale your private network for many boxes. One approach is obviously to edit /etc/hosts (but this gets annoying when you add a new box). A better way is to create an internal DNS zone (via the digital ocean web interface) and have your droplets use it:

Steps

setup the internal DNS zone file

1. Login to digital ocean
2. Click "DNS" on the right hand menu
