The easiest way to clear your DNS cache is to use the Run dialog box, a Windows tool that allows you to quickly run commands, launch apps, and open files if you know what to type.

Why Flush Your DNS Cache

The purpose of DNS is to let you visit websites by typing a URL instead of an IP address. The point of a DNS cache is to speed up website access by making it so that your computer doesn’t have to wait for a DNS lookup every time you visit a website that you’ve already been to in the past. If this local record ends up getting corrupted, it’s out of date, or you connected to a DNS server that provided incorrect information, you may have trouble accessing websites. By clearing or flushing your DNS cache, you force your computer to check a DNS server when visiting sites because there is no longer a local record. While Windows 10 maintains a local DNS cache that you can flush with the methods found in this article, your router may also keep a cache. If you find that flushing your DNS in Windows 10 doesn’t fix your internet connectivity problem, then rebooting your router may help. Was this page helpful? Thanks for letting us know!
