title: What does the dualstack prefix mean in AWS ELB?
body: <p>When I add an ELB as Alias Target in AWS Route 53, it automatically adds the <code>dualstack</code> prefix to my ELB DNS. What does this represent?</p>
  
  <p>When I try <code>dig</code>, both returns the same endpoints.</p>
  
  <p>Note: This is an internal load balancer.</p>
