DNS resolves domain name to IP addresses so people do not have to remember a series of numbers (IP addresses) when trying to visit a website. In order the speed up this process and reduce the traffic on the DNS servers, most computer operating systems will store or cache DNS lookups on your computer locally. At times, you may need to clear the cache to see changes . In this tutorial, we'll show you how to clear the DNS cache for the major operating systems on the market. Typically, this process is referred to as clearing or flushing the local DNS cache.

Flushing Local DNS Cache in Windows

  • Windows 7 and Vista:
    • Click on the Start Menu 
    • Type cmd in the search box
    • Right click on cmd in the programs search results and choosr Run as Administrator
  •  

  • Windows 98/NT/2000/XP
    • Click on the Start Menu
    • Select Run

Flushing Local DNS Cache in Linux

With the various distributions of Linux, you will find that by some run a daemon in the background to manage DNS cache, while others do not. Ubuntu is a good example of a distribution that doesn't run this daemon by default. If you're running Ubuntu and you have not already installed the ncsd daemon, you can install it with this command:

sudo aptitude install nscd

To restart the ncsd deamon in Linux, use this command:

sudo /etc/init.d/networking restart
