How to Flush DNS Cache in Windows 11: A Step-by-Step Guide

Understanding DNS Cache

Before we dive into the process of flushing DNS cache in Windows 11, it’s essential to understand what DNS cache is and why it’s necessary. DNS (Domain Name System) cache is a temporary storage of DNS records that allows your device to quickly look up domain names. However, if your DNS cache becomes outdated or corrupted, your device may struggle to resolve domain names, leading to issues with internet connectivity, DNS resolution, and overall system performance.

Flushing DNS cache in Windows 11 is crucial for several reasons:

Improved DNS Resolution: A flushed DNS cache ensures that your device can resolve domain names quickly and accurately, reducing the likelihood of DNS resolution errors.

Enhanced System Performance: A clean DNS cache improves system performance by reducing the load on your device’s DNS resolver, allowing it to handle more requests and maintain a stable connection.

Better Internet Connectivity: A flushed DNS cache ensures that your device can connect to the internet without encountering DNS resolution errors, resulting in faster and more reliable internet connectivity.
