If you’re having connection issues, you might want to clear your DNS cache. In this article, you’ll learn the benefits of it and how to flush DNS cache on popular operating systems.

  • Ways to Flush DNS Cache

Reasons to Flush DNS Cache Periodically

Similar to web browsers, operating systems also store cache files called Domain Name System (DNS) cache. The cache files contain information about all visited websites — hostnames, IP addresses, and resources records.

Most operating systems perform DNS caching to lessen DNS servers’ burden during high traffic. The caches’ validity period is determined by Time To Live (TTL). As long as the cache files are still valid, they will answer content requests without having to go through the DNS server.

Despite so, using corrupt or outdated DNS cache files can lead to error and security vulnerabilities. Therefore, we recommend you to flush DNS cache periodically.

Here are the reasons why you should clear DNS cache regularly:

  • Prevent search behavior tracking — storing DNS records makes it easier for hackers to predict your browser history.
  • Security — DNS cache files are the main target for DNS spoofing, which endangers users’ sensitive information like login credentials and personal data.
  • Solve technical problems — forcing the operating system to search updated DNS records can solve connection issues and incorrectly displayed web content.
