How To Flush DNS

Sometime we enters correct address of a site still we gets negative result.(Like server not found in our browser but opening correctly in friends browser).All these problems are caused due to wrong DNS cache.Let's see how?...


Most operating systems automatically  cache IP address and other DNS results. This is done to speed up the process.For example if we visit google first time ,then it will save all info related to IP address and DNS. If we visit google second time ,system will use already stored info and less time to communicate with host server .


Sometimes bad results are cached and cause problem in subsequent communication with host server ,so for resolving this problem flushing of DNS is done.....
