Google Chrome is the fastest web browser on this planet. Part of this fastness comes from its ability to prefetch the domain name resolutions for the most visited domains names. The DNS service is how a domain name like trishtech.com are resolved into the IP address like 18.104.22.168. Google Chrome saves the time to resolve the domain names into respective IP addresses by prefetching the most common domain names and storing them in the Host Resolver Cache. But if you change your DNS name server and want to clear the Host Resolver Cache, then Chrome allows you to do that too. You can clear Host Resolver Cache in the following way:
- Open Google Chrome browser.
- In the address bar (omnibar) type chrome://net-internals and press Enter.
- In the page that opens up, click on the DNS link in the left-side bar. If you scroll down a little, you can see all the prefeched entries in the host resolver cache.
- Click on the Clear host cache button to clear the host resolver cache entries. You would find that the entries in the list would be immediately cleared.
Often I experiment with web design on my locally installed Apache web server. For this I have to make changes in the HOSTS file but this messes up the host resolver cache in Google Chrome. By clearing the host resolver cache, you can force Google Chrome to resolve the domains again.
