Introduction: Chrome.//Net-Internals/Dns Clear
Google Chrome includes tools for managing DNS (Domain Name System) cache, which can be crucial for troubleshooting and improving browsing performance. While specific URLs like “chrome://net-internals/dns clear” aren’t accessible in the traditional sense, users can still manually clear DNS cache through Chrome’s settings or advanced tools to resolve browsing issues caused by outdated DNS records.
What is DNS Cache Clearing?
DNS caching involves storing recent DNS resolutions locally on a device or browser. This cache helps speed up subsequent visits to websites by avoiding the need for repeated DNS lookups. However, outdated or incorrect entries in the DNS cache can lead to connectivity issues or website loading errors. Clearing the DNS cache removes these entries, forcing Chrome to re-query DNS servers for fresh information.
Methods to Clear DNS Cache in Google Chrome

- Access Settings:
- Click on the three dots in the top-right corner (menu icon).
