Clear DNS cache for Windows/Mac/Linux

The DNS cache on a computer stores the IP addresses of network locations, both public (Internet) and private. Once an IP address for any network location (e.g. a website) is learned, then a typical computer will remember that address for 24 hours. To force a computer to re-learn IP address and DNS information, its cache needs to clear. This can be done using the following methods:

Windows

Open the Start menu.

Go to Run. If you do not see the Run command in Vista, search for "run" in the Search bar.

In the Run text box, type: ipconfig /flushdns

Press Enter or Return, and the DNS cache will be cleared.

Mac

Open the Terminal application.

Type: dscacheutil -flushcache

Press Enter or Return, and the DNS cache will be cleared.

Linux  

To flush the DNS cache in Linux, you need to restart the nscd daemon. 

Open a terminal window.

Type /etc/rc.d/init.d/nscd restart in your terminal.

Press Enter or Return, and the DNS cache will be cleared.
