How to flush DNS Cache in Windows 10

  1. What’s the point of the DNS client service? It takes no time at all to perform the DNS lookup and have the correct address. It takes much longer to try the cached value, empty the cache because it’s wrong, and try again. I solidly maintain that caches cost time, they don’t save it.

  2. The point is that 99% of the time, the cached DNSs are correct. It would take considerably more time and resources to perform the DNS lookup each time. I’m also not so sure you understand just how much the DNS cache is referred to. Just because you visit example.com once, does not mean that the DNS must be resolved once. It must be resolved for every page you visit, every image that loads, every javascript etc. – visiting a single page does not mean that everything is sent in one single request.

  3. I have Windows 8.1 and I’ve had to flush my DNS cache every day, multiple times. Is there a way to solve this?

  4. Hi i am not able to clear DNS cache. Even after using ipconfig /flushdns command its showing some data if i use ipconfig /displaydns.. can any one help me

  5. After you do ‘ipconfig /flushdns’, don’t forget to clear the cache in your browser to see the effect of any DNS resolver changes, such as edits of your local HOSTS file. Also, note that you can always view the contents of the local DNS cache using command ‘ipconfig /displaydns > dns.txt’. The list will be in file dns.txt in the current folder.
