title: How to force DNS refresh for a website?
body: <p>I'm moving my web application to another server and in the next few days I'll refresh the DNS to point to the new IP location.</p>
  
  <p>Unfortunately some browsers and SOs keep a DNS cache that will make users point to the old IP location. Some users are rookies and they'll not refresh the DNS cache manually and I know we'll lose a lot of them in the first weeks after this change.</p>
  
  <p>Is there anyway to force this DNS cache to refresh so it'll be transparent for our final users?</p>
