Most computers that are connected to the Internet do what is called DNS caching..
This means that domain names and web addresses of the websites you visit
are stored so that when you visit a page more than once,
it can load faster because it has been cached..
However, which often be a problem is that the DNS cache
can sometimes be corrupted and it causes problems like some websites
that can not be accessed when the internet connection has no problem..
At this point the DNS flush is needed..
DNS flush will force the computer to clear the DNS cache
or in other words it forces the computer to erase all memory
of the domain name and the IP address associated with the domain name..
Once the DNS cache is empty,
the computer will start asking for new data from the DNS server
and it will build DNS cache from the beginning..
If you want to erase the information in this cache,
it is called flushing the DNS..
Follow these steps MANUALLY
