Flush DNS basic concepts it to remove already resolve IP addresses of domainnames from your system.... this has nothing to do with visit pages.... those cache are build up by BROWSERS and you have to clear by there method.

ipconfig /flushdns only flush all the stored resolved values.... and it will not improved speed as well because you need to query again your root server to resolve and it takes time. Always having dns cache make it faster as it resole locally......

it can be helpful, if any of your site changes it IP address and your server/machine still see the old IP....

Yes true flushDNS is nothing to do with visit pages, as i discuss Cache is the place where visit pages are stored stored temporarly and it is not must that due to flushdns the process will be sppedup but it can helps out in this.

Anyway thnx for the suggestion and correction.
