DNS Flush

What basically it do ?

The domain name service (DNS) act as converter that change domain name into an IP address. To check lists of DNS mapping , you can write down ipconfig/displaydns. Here we can see the regular website of IP Address that we browsing like htpps://www.google.com.  When you repeatedly use a same URL,  our computer will lookup IP Address inside local cache instead fetching from DNS, this is because IP address are not regularly changed. Heres the thing, when the server were moved to another website or perhaps IP Address has been changed this probably will cause you to see old website for a while. When you do a ipconfig /flushdns, your system clears the cache of name to ip entries and reloads them from the connected DNS server.
