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

Click "DNS" on the right hand menu

	To implement a trait on a type, the trait or the type has to be local to the code you work on. It is called the orphan rule.
	To get around this restriction, we can use the newtype pattern which involves creating a new type in a tuple struct.
	Both Vec<T> and Display trait are from the standard library and neither is local to our code.
	We are not able to implement Display trait to Vec<T>. But we can construct a wrapper type holding an instance of Vec<T> and implement Display trait on it.
	In the following example, VecWrapper<T> struct wraps Vec<T> and implements Display trait.
	To get all the methods of Vec<T> available to VecWrapper, Deref trait is implemented on it.
