title: Do URLs corresponding to IP address get cached in browsers?
body: <p>Scenario is : We had some   x.x.x.x Ip address corresponding to URL www.website.com for our website URL .We changed it so some y.y.y.y ip address corresponding to same URL www.website.com. 
  But a problem occured and some of our customers were not able to reach our server(website) using that URL. </p>
  
  <pre><code>How new ip addresses get published across internet?     
  How much time does it normally take,to complete this process. 
  Can it be possible that some browsers due to cached IP address,don't ask to DSN to reslove URL to IP ?
  Do browers cache "IP TO URL resolving" ?
