Most of the modern Internet browser softwares like IE, Firefox, Google Chrome etc provide “Private Browsing mode”. In this private browsing mode the Internet cookies are not saved, the browsing history is not maintained and no other data is kept after you close the browser. This is a good relief if you want to browse Internet privately on a shared computer for any reason. But, is this more truly private ? Yes it seems like, because the Internet browsers do the best they can do, but yet there are traces of which websites you opened on your computer.
These traces are not kept by the browser, but kept by the operating systems like Windows, Linux, or MAC OS. These traces are nothing but your DNS cache which is maintained by the OS. It stores which website has what IP address, this is a feature which helps to open websites faster by saving on time which is spent on checking the IP address of a domain using outside name server. Although DNS cache is a good feature to speed up the Internet browsing experience, but it has potential to bust your private Internet browsing. In this article, I will show you how you can see and clear the DNS cache to remove the traces of the websites which you have visited in the private browsing mode.
