How Can You Use Chrome://net-internals/#dns to Clear the DNS Cache in Chrome?

Before proceeding with this post, it is essential to understand what a DNS cache is and how DNS cache clearing works. DNS cache refers to a small amount of data about regularly used domains and websites. The main objective of the DNS cache is to speed up browsing, and when remote or ISP DNS servers are down, you can reach that website using Chrome DNS cache.

However, when a website changes its DNS entry or due to some other faulty network condition, you need to clear out the DNS cache to reach to correct IP address on the Internet.

In simple terms, DNS cache clearing means getting rid of existing cached data from Google Chrome. Once cleared, Google Chrome will ask for all the new IP addresses and DNS information for that website.

Here’s the process to clear the DNS cache on the Google Chrome browser.

Open a new tab
Now type the URL in the search box section: chrome://net-internals/#dns
Hit the Clear Host Cache button
Now you are almost done, as DNS is cleared out
Open another tab and type the URL, Chrome://net-internals/#sockets
Click on the Flush Socket Pools button
Now, close the Google Chrome tab
