# How to Flush DNS

Command Prompt and Windows Powershell, which is a new addition to Windows, can be used to clear DNS cache.

**Option 1 – Command Prompt**

To reset the DNS resolver cache, perform the following steps:

1. Click the `Start` button, then type `cmd`
2. Right-click `Command Prompt`, then choose `Run as Administrator`.
3. Type `ipconfig /flushdns` then press `Enter`. (be sure there is a space before the slash)

A command box will flash on the screen for a split second, and the DNS Resolver cache is cleared
