How do I flush my local DNS cache?

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):

1. Click on Start->Run
2. type:

ipconfig /flushdns

Your DNS cache has been flushed.

Note

for Windows7, try this FlushDNS.bat script.

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.

To flush the DNS cache in Linux

in your terminal, type:

# /etc/rc.d/init.d/nscd restart

or

# service nscd restart

Your DNS cache has been flushed.

Please note, many distributions do not cache DNS, so if nscd is not installed on your distro, this is not needed.
