The Domain Name Service (DNS) cache on a computer is a local cache of domain name-to-IP address information that is saved locally for easier access by applications that access the Web. If you know that there have been changes made to the DNS entries for certain websites, you can clean your local DNS cache so that it stops incorrectly loading those updated websites.
