The exact steps on how to flush DNS under Linux really depend on the installed Linux distribution, and installed system packages. Please check with your distribution documentation on the exact steps you need to take to Flush your DNS cache. Please note that some distributions by default do not install DNS caching service, so flushing the DNS cache might not be required or possible without further package manipulation.
Normally you will need to restart the caching service, or if you have local name server by using commands such as:
- /etc/init.d/nscd restart
- /etc/init.d/named restart
- or nscd -I hosts
In combination with the above – you may need to reboot your computer and/or clear your browser cache.
If the above do not help, please allow 24-72 hours for the new DNS change to take place.
