title: Amazon AWS/EC2 - How to put to servers on same "private network"
body: <p>I'm new at Amazon AWS/EC2. Basically, I have two EC2 instances set up and running - 2x t2.medium, Windows 2012 servers, etc. </p>
  
  <p>Each server has it's own public and private ip addresses from different subnets:</p>
  
  <pre><code>Server 1: 53.171.139.195/171.30.51.181
  Server 2: 53.164.26.68/171.30.59.198
  </code></pre>
  
  <p>I simply need these servers to be able to communicate with one another on the same private network.</p>
  
  <p>I see things like elastic ip's, vpc's. Still researching, but I'm not sure what I need. Can this be done and what do I need to configure?</p>
  
  <p><strong>Update:</strong>
  Based on @Bram's response below, I looked at VPC's. Apparently, a default VPC was created when I started my instances.</p>
  
  <pre><code>171.30.0.0/16
  </code></pre>
  
  <p>So... Are the on the same subnet by default???</p>
