What your DNS cache does is to temporarily store the locations (IP addresses) of all your recently viewed websites on your local device so that next time you access those sites, they load faster. This is very convenient as your computer will not have to look for the corresponding IP address of a website each time you try to open the page. This cache automatically updates over a certain time. However, if the location of the website changes before the entry in your DNS cache updates, your computer will still be looking for it at its old address. To avoid that, all you have to do is flush the DNS cache of your computer. Here is how to do it:
ipconfig /flushdns
Windows IP configuration successfully flushed the DNS Resolver Cache.
To run the command for flushing DNS, you must know the computer’s administrator account password.
MacOS 10.10.4 and above: sudo killall -HUP mDNSResponder
MacOS 10.10.1, 10.10.2, and 10.10.3: sudo discoveryutil mdnsflushcache
MacOS 10.7, 10.8, and 10.9: sudo killall -HUP mDNSResponder
MacOS 10.5 and 10.6: sudo dscacheutil -flushcache
# service nscd restart
or
# /etc/init.d/nscd restart
sudo apt-get install nscd
sudo /etc/init.d/nscd restart
