title: Is it possible that one domain name has multiple corresponding IP addresses?
body: <p>For example, when we connect to <code>www.example.com</code>, at first we try to connect to <code>192.0.2.1</code>. And if first try fails, then we try <code>192.0.2.222</code>.</p>
  
  <p>Is it possible? Can we register multiple backup IP addresses for one domain name?</p>
