Flush DNS Cache in Ubuntu Using the following command
sudo /etc/init.d/nscd restart
why clear DNS cache ?
So if you have an invalid DNS entry cached on your local client you’ll need to flush it out of the cache so your client can do a new lookup and get the correct information. Or your other option is to wait until that DNS entry expires and the cache flushes it automatically… which typically takes about 24 hours.
