body: <p>As the title says. Why can we only assign a public IP address of SKU <strong>basic</strong> and <strong>dynamic</strong> (which is a legacy type and does not support <strong>Availability Zone Scenarios</strong>)? </p>
  
  <p>Doesn't that complicate things e.g. when connecting with on-prem VPN devices?</p>
