title: AWS setting CIRD
body: <p>I know this topic has a lot information all over but I can't find an answer to a simple question. </p>
  
  <p>I am willing to have a subnet for each availability zone in my region (3 zones). My VPC CIDR is 10.0.0.0/19 and I want each subnet to have same amount of IPs. My question is what is the CIDR Block I should assign for each subnet?</p>
