DNS information answers your browser where to locate a website. Your computer stores this data in its local cache to quickly point browsers accurately.

In this tutorial, I will explain to you how to free your DNS cache on your Windows computer and Chrome browser.

This tutorial will let you to quickly refresh DNS records cached on your device and assist you in troubleshooting website issues.

What is DNS Cache?

DNS cache is the same as an address book. Your computer caches the Domain Name System (DNS) information on every website you access.

DNS is a technology that reports to your computer about the associated IP address of a domain name.

Preserving the DNS data in a local DNS cache helps your browser quickly connect to a website.

At first, your browser will look for DNS information in the local cache once you enter a domain name in the browser’s address bar. If the browser gets the details, then the browser uses the DNS cache to visit the website.

If your local computer had not cached the DNS information, then the browser will obtain it from other DNS servers across the internet.

Having a DNS cache helps the browser takes the fastest route to get the DNS information of the website you visit.

However, local DNS cache may sometime cause a problem. For example, when you are moving your website to a new host or a new domain name.

When a domain owner makes a DNS change, the DNS data may not get refreshed instantly on your computer. Due to this delay, you may end up visiting the old website or see a not found error.

Updated DNS records will eventually get refreshed, but you don’t need to wait, and you can clear DNS cache manually.
