Chrome DNS cache a.k.a Chrome Host Cache is a temporary store of DNS records that Chrome uses to resolve domain names to IP addresses. This cache helps to speed up the browsing experience by avoiding the need to repeatedly contact a DNS server for the same information.
Let’s understand how to DNS Cache in Chrome works:
When you visit a website for the first time, Chrome will contact a DNS server to resolve the domain name to an IP address. The DNS server will return the IP address to Chrome, and Chrome will store this information in its cache. The next time you visit the same website, Chrome will look for the IP address in its cache and use it to connect to the website, without having to contact the DNS server again.
Sometimes corrupt or outdated Chrome DNS cache can lead to issues like incorrect or slow website loading. Clearing the DNS cache in the Chrome browser can help you in resolving such problems.
Although it’s a one-click process, the option to achieve this is not available in the browser settings, like you can Clear Browser Cache. You need to visit Chrome’s internal pages to make that thing happen.
In case, you made landed on this blog post, then it’s highly possible you’re facing issues accessing websites due to the DNS cache and would like to clear the DNS cache to resolve the issue, right?
How to Clear DNS Cache in Chrome (Host Cache)

Open Chrome browser and type or copy-paste
chrome://net-internals/#dns in the address bar and hit enter.
In the Chrome DNS Lookup page, locate the Host resolver cache option and click on the Clear host cache button.
On this page, there’s a DNS lookup where you can enter the domain name for example (geekermag.com) in the available field. Here, you can check the IP address of the domain before and after you have cleared the host cache.
If the problematic domain has chosen a different IP address, the lookup results will show this change.
