Flushing the DNS cache on your computer

These instructions will help you clear DNS cache (if needed). If you are connecting through a router, you will likely need to reset the router to clear DNS cache on it.

To flush DNS cache in Microsoft Windows (Win XP, Win ME, Win 2000):

• Click on Start->Run
• type: ipconfig /flushdns
• Your DNS cache has just been flushed.

To flush the DNS cache in Linux, restart the nscd daemon (not all distributions use nscd):

• Please note, many distributions do not cache DNS, so if nscd is not installed on your distro, this is not needed.
• in your terminal, type: /etc/rc.d/init.d/nscd restart
• Your DNS cache has been flushed.

To flush the DNS cache in Mac OS X:

• in your terminal, type: dscacheutil -flushcache
• on older versions of OS X, type:lookupd -flushcache
• Your DNS cache has been flushed.
