Windows reset dns cache

• Modern browsers, OS, and DNS clients store cache of IP addresses and other DNS information automatically. When a computer visits a website for the first time, it stores the website’s DNS information in the cache, and on the next visit of the same website, it looks in the cache to see if the web site’s information is present to use. An old version of a site opens if the website’s DNS information has changed since the computer’s last visit.

  Flushing the cache removes all the data stored in the cache, forcing the computer to find the new DNS information for the website. It is usually done to speed up the process and minimize requests for the same hostnames. When IP addresses are changed, or bad results are cached, its necessary to clear the DNS cache. DNS cache can be cleared via command line or from browsers also. Steps to flush DNS Cache for major operating systems and browsers are as below.

Are you facing website loading issues or worried about data privacy offline and online? You must know how to flush and reset the DNS cache in your Windows 11 or earlier PCs!

When you browse websites, the Windows 11 PC plays a major role in helping your web browser load the queried pages faster by caching the Domain Name System (DNS) addresses of the websites you visit. Problems in this DNS cache file can stop you from visiting an updated website, cloud app, or other online resources that rely on DNS addresses.

Flushing the DNS resolver cache can help resolve DNS-related problems in Microsoft Windows 11 and previous versions. Issues would include website not found errors or not being able to view certain web pages that have changed. Read on to learn the methods to flush and reset the DNS resolver cache in Windows 11.

What Is DNS Cache?

While you recognize a website by its URL like technipages.com, the web browser or computer recognizes the same website using its IP address, which is 172.67.69.195. Now, all these IP addresses for billions of websites are available in various DNS servers around the world. Your Internet Service Provider (ISP) also maintains a secondary DNS server cache as a backup to the primary DNS servers.

Картинка с сайта: www.technipages.com

When you type an URL in the address bar of Chrome or Mozilla web browser for the first time, it requests the IP address from a nearby DNS server to open the web page. The Windows 11 PC copies the resolved IP from the first query and saves it in a DNS resolver cache.

The next time you open the same web page, the web browser no longer requests a DNS server to translate the URL to an IP address. It takes help from the DNS resolver cache in your operating system. This is known as a DNS cache of a local computer like Windows 11. Similar to Windows PCs, macOS, Linux, etc., computers also maintain a local cache copy of all the websites that you visit.

What Is Flush DNS and What Does It Do?

Flush DNS is a common Command Prompt code for all modern Windows operating systems since Windows 2000. You can use this code to force the Windows PC to clear the records in its DNS resolver cache. Operating system developers allow the users to do this manually to avoid data security issues, website loading problems, and other DNS address-related issues.

After you use the Flush DNS command, Windows wipes the entire DNS cache that it built since the recent clean installation of Windows 11 or any other Windows operating system. The web browsers from now on need to send a DNS resolver query to the nearest DNS server to get the latest IP of the URL you’re trying to access. Soon, Windows 11 will record these resolved IPs in the local DNS resolver cache.

FAQ

What is the DNS Resolver Cache?

Whenever you visit a website using its domain name (i.e. microsoft.com), your browser is directed to a DNS server where it learns the IP address of that website. You are then directed to that website. A record of the IP address that the domain name points to is created within Windows so that if you visit that same website again, the information is accessed quicker. These records that get created make up the DNS Resolver Cache.

Why would flushing the DNS Resolver Cache fix anything?

Sometimes an IP address to a site may change. If the DNS Resolver Cache has the old IP address record, it may result in your computer not being able to reach the site. Cached data can also become corrupt. Therefore, clearing it is a step you can take whenever you cannot connect to a site.

Can I view the data in the DNS Resolver Cache?

Yes, you can. From a Command Prompt, you can use the following command to view the data in the DNS resolver cache:

ipconfig /displaydns

Картинка с сайта: www.technipages.com

Alternatively, you can use the Microsoft PowerShell terminal on Windows 11 or 10 computer and execute the following code in it to view the data stored in your Windows PC’s DNS resolver cache:

Get-DnsClientCache

Conclusion

So, now you know how to flush and reset the DNS resolver cache in a Windows 11 PC. You also learned how to delete the local cache copy of DNS using Command Prompt and Run command dialog box in earlier versions of Windows like Windows 8, 7, Vista, XP, etc. Give the above methods a try when you face internet connectivity issues with a specific website or app. Don’t forget to comment below if I missed any other steps to flush and reset the DNS resolver cache in Windows PCs.

Next up, Why Is It Important to Route DNS Traffic Over Your VPN?

The Domain Name System (DNS) translates human-readable domain names (like www.example.com) into machine-readable IP addresses (like 192.0.2.1). And DNS cache is a temporary database maintained by your computer that stores recently accessed domain names and their corresponding IP addresses. DNS cache helps speed up the process of resolving domain names to IP addresses, thus improving your internet browsing experience. However, sometimes the DNS cache can become outdated or corrupted, leading to various connectivity issues. In such cases, you can run Flush DNS command to remove this stored cache and forces your device to retrieve the information from the DNS again. If you are experiencing internet connectivity problems, Here is how to flush DNS cache on Windows 11 to fix such problems.

The DNS cache (also known as DNS Resolver Cache) stores recently accessed domain names and their corresponding IP addresses for a specified period. The next time you open the same web page, the web browser no longer requests a DNS server to translate the URL to an IP address. It takes help from the DNS resolver cache in your operating system.

The DNS cache improves the performance and efficiency of your internet browsing experience. However, over time, the information in the cache can become outdated or corrupted, leading to potential connectivity issues, such as trouble accessing certain websites, slow-loading web pages and more. In such situations, you need flush DNS cache to allow your Windows computer to communicate with the host correctly.
