How to Flush DNS Resolver Cache in Windows 10


Information A DNS (Domain Name System) resolver cache is a temporary database, maintained by Windows, that contains records of all your recent visits and attempted visits to websites and other Internet domains.

The Internet relies on the Domain Name System (DNS) to maintain an index of all public websites and their corresponding IP addresses. Every time a user visits a website by its name (such as "tenforums.com"), the user's web browser initiates a request out to the Internet, but this request cannot be completed until the website name is converted into an IP address.

This conversion process is called name resolution and is the job of DNS, but it takes time. A DNS cache attempts to speed up the process by handling the name resolution before the request is sent out to the Internet.

If the IP address of a website changes before your DNS cache updates, you may not be able to load the webpage. If you are running into a lot of Page Not Found errors and you know you are connected to the Internet, you could try flushing your DNS cache to have your computer request new information.

This tutorial will show you how to flush your DNS resolver cache in Windows 10.



Here's How:

1. Open a command prompt.

2. Enter the command below into the command prompt, and press Enter.
*Arrow ipconfig /flushdns
3. When it has Successfully flushed the DNS Resolver Cache, you can close the command prompt if you like.


Tip If you get a Could not flush the DNS Resolver Cache: Function failed during execution. error message, then make sure that the DNS Client service is enabled and running, and try again.






That's it,
Shawn

flush dns

Hello,

Sorry for the delay in response.



No, Flush DNS will not reset the IP to default. It only flushes or resets the

contents of the DNS client resolver cache.



Hope this information is helpful. Please do let us know if you need further

assistance.



Thank you.

 

Windows 10 DNS caching problem

After some time of messing around with the two windows 10 machines I have, one a laptop, the other a surface pro 4, I've consistently hit the DNS resolution issues that many other people have reported.

Basically what happens is DNS resolution stops functioning for a period of time, however previously cached domains still resolve. A simple and effective solution to this is to just flush dns cache with ipconfig /flushdns command. More frustrating is that
it appears when DNS resolution fails, nxdomain is cached as well (which may actually be a significant part of the problem).

Microsoft network engineering should take a good look at how the resolver cache is handled, as it appears that some failure which results in DNS resolution failure will end up with a cached nxdomain (which should never happen). The fact that a simple dns
flush fixes the problem instantly strongly suggests that there is a bug in this part of the code which needs closer examination.

 

flush dns

Hi,

Using Ipconfig/flushdns helps you to flush or resets the contents of the DNS client resolver cache. You can use this procedure to remove negative cache entries from the cache, as well as any other entries that have been added

dynamically.


Hope this information is helpful.

Thank you.

 

DNS Cache Users

Just a note. If you change your DNS server, say go to Google (8.8.8.8) or switch to OpenDNS or any other than your default ISP, it's a good idea to flush the DNS. It will get rid of any possible "redirects" from previous DNS and will rebuild.
