Introduction: Hi there, Readers!
Welcome to our comprehensive guide on how to flush DNS cache in Windows 11. DNS (Domain Name System) plays a vital role in translating human-readable domain names into numerical IP addresses, enabling seamless web browsing and online activities. However, a congested or corrupted DNS cache can lead to internet connectivity issues, including slow page loads, broken connections, and intermittent website access. Flushing the DNS cache can resolve these issues by refreshing the cache and eliminating any outdated or incorrect entries.
Section 1: Why Flush DNS Cache?
Understanding the DNS Cache
When you access a website, your operating system queries a DNS server to resolve the domain name into its corresponding IP address. This IP address is then stored in the local DNS cache for quick retrieval in subsequent requests. Over time, this cache can accumulate obsolete or incorrect entries, which can interfere with internet connectivity.
Benefits of Flushing DNS Cache
Regularly flushing the DNS cache offers several benefits:
- Improves Internet Connectivity: By removing outdated or corrupted entries, flushing the DNS cache ensures that your device is accessing the most accurate and up-to-date DNS information, resulting in faster and more reliable internet access.
- Resolves Domain Name Resolution Errors: If you are experiencing difficulty accessing certain websites, flushing the DNS cache can help resolve domain name resolution errors caused by corrupted or expired DNS entries.
- Enhances Network Troubleshooting: Flushing the DNS cache can be a useful step in troubleshooting network connectivity issues, as it eliminates the DNS cache as a potential source of the problem.

Using Third-Party DNS Servers
If you are still experiencing DNS issues after flushing the DNS cache, consider using a third-party DNS server such as Google Public DNS or Cloudflare DNS. These servers often provide faster and more reliable DNS resolution.
Static IP Configuration
In some cases, assigning a static IP address to your device can resolve persistent DNS issues. However, this should only be done if you have a thorough understanding of network configuration.
Section 4: DNS Cache Flushing in Different Scenarios
After Changing Network Settings
When changing network settings, such as switching Wi-Fi networks or connecting to a VPN, it is advisable to flush the DNS cache to ensure that the new settings are applied correctly.
After Updating Windows
Windows updates can sometimes introduce changes to the DNS cache. Flushing the cache after an update can help resolve any compatibility issues or incorrect entries.
Troubleshooting Network Connectivity Issues
Flushing the DNS cache is an essential step in troubleshooting network connectivity issues. It eliminates the DNS cache as a potential source of the problem, allowing you to focus on other potential causes.
