title: AWS - Acceidentally created VPC in 172.168.0.0/16 CIDR block, effects?
body: <p>We accidentally created a VPC in 172.168.0.0/16 CIDR block, we realize we need to change this, however, does anyone know the ill effects of such an issue? </p>
  
  <p>Will every call to a local ip (as we expect) actually go via internet?</p>
  
  <p>Can we get an IP conflict with somebody who has taken up these IPs?</p>
  
  <p>Can our internal traffic actually go out to the internet if somebody has an IP in this block?</p>
  
  <p>Edit:</p>
  
  <p>Our subnets routing tables route the traffic in this range into the local network, however I am pretty sure there will still be adverse effects.</p>
