Chrome.//net-internals/dns | How to Clear DNS Cache

Before discussing chrome.//net-internals/dns, you should know about the DNS server, what DNS is, and its role in chrome internals. 

What is a DNS Server?

DNS (Domain Name System) is a hub with all the IP addresses of websites available on the Internet. Humans access websites with domain names, whereas web browsers act through IP addresses (Internet Protocol). DNS converts domain names (hostnames) into IP addresses so browsers can load and display a website.

For example, forbes.com is a domain whose IP address is 151.101.194.49 (the IP address can be found on any online tools for free).

DNS acts like a contacts book whenever a person searches for a website on the internet; DNS finds the correct IP address, and that site IP address redirects to a device such as a mobile or desktop to the proper place to access the site data.

Every post or article has an IP address; when the DNS server finds the IP address, browsers pick it up and send data to the content delivery network (CDN) or origin servers. Once this process is complete, a user can see the website he or she searches for on the browser.

What does chrome.//net-internals/dns do?

Google Chrome is one of the most used browsers, compared to Mozilla Firefox, Safari, DuckDuckgo, Opera, and others. Most people choose Chrome because it is one of the fastest browsers. Every browser has a DNS system, which helps browsers communicate with websites.  

If your browser is running slow or getting stuck, you should clear or clean out your browser cache with the help of DNS chrome.//net-internals/dns.

Chrome.//net-internals/dns is used to clear the cache in the Chrome browser. Read this blog to learn how to clear the DNS cache in Google Chrome without completely shutting down.

Chrome browsers have an inbuilt DNS and proxy cache server to improve performance. Users can quickly clear the DNS manually. 

The work of chrome.//net-internals/dns is to clear the host cache from the browser by using chrome DNS. 

Whenever a user searches for information on the browser, that particular website’s DNS information is stored in the browser for future purposes; when a user opens that same website again on the same desktop and browser, it doesn’t load more and displays the recently opened website quickly with the help of DNS. 

Due to this, DNS data-storing browsers load and run slowly. To solve the problem of Chrome browser’s slow processing, you have to use Chrome.//net-internals/dns. 

This is a type of code: “chrome://net-internals/#dns.” When you copy and paste this code on Chrome, you will land on a DNS lookup page. By going there, you can clear the host cache.
