title: Override DNS lookup for URL in AWS vpc
body: <p>I have few public ips for which I want my resources (ec2, lambda etc) under vpc access via some DNS.</p>
  <p>On VM we usually edit hostfile but wanted to know how I can achieve this on AWS.</p>
  <p>Say if external IP I want to access is 1.2.3.4, I want it to be resolved when I ping to some.example.com(non existing dns)</p>
  <p>Thanks</p>
