When Google Chrome encounters issues related to DNS, it’s often due to outdated or corrupted DNS information stored in the browser. To resolve these connectivity issues, it’s necessary to clear Chrome’s DNS cache. This can improve the browser’s performance and prevent interruptions when accessing websites. In this guide, we’ll show how to use Chrome’s net internals tool to flush the DNS cache, both on desktop and Android devices.
Flushing DNS on Chrome ensures that the browser retrieves fresh DNS entries from the system, avoiding problems caused by an old DNS entry. This process is quick and effective for resolving issues like outdated or corrupt information. For Linux, Apple, and other operating systems, similar steps are used to clear the DNS cache at the browser or system level, including manually shutting down DNS proxy caching servers.
What is DNS and How Does it Work?
The DNS (Domain Name System) acts like the internet’s address book, helping browsers find the correct IP address for a website. When you type an address like “example.com” into your browser, the DNS server quickly translates it into an IP address, such as 192.0.2.1, which is how computers communicate. This process is crucial for loading websites, sending emails, and using other online services. Without this translation, your browser wouldn’t know how to connect to these resources.
Every time you access a website, your browser stores this information in a DNS cache, keeping a record of all the queries it has made to the DNS server. When you enter a new URL, the browser sends a request to the DNS server to fetch the URL’s IP address, then loads the site into the window. This caching system speeds up the process, but over time, it may need to be cleared to prevent loading issues or outdated data.
What Is chrome://net-internals/#dns?
The chrome://net-internals/#dns page is a powerful tool within Chrome known as Net-Internals. It provides a real-time visualization of network-related events and the state of your browser. Using this tool, you can view detailed NetLog logs and load NetLog dumps from both earlier dates and later dates to troubleshoot and debug any network issues. This Net-internals/#dns feature helps in understanding how Chrome resolves domain names by showing DNS resolver cache, DNS requests, and response data.
For web developers and users who need to gain insight into their browser’s performance, this tool is incredibly useful. It offers a backstage look at the inner workings of Chrome and other Chromium-based browsers like Opera and Microsoft Edge. By analyzing the logs and data, you can identify and address issues affecting network performance, ensuring a smoother browsing experience.
At what point is it essential to flush the DNS cache in Chrome?
Flushing the DNS cache in Chrome becomes essential when you encounter issues such as
- DNS error messages like DNS_PROBE_FINISHED_NXDOMAIN or ERR_NAME_NOT_RESOLVED. These errors typically indicate that your browser is struggling to resolve domain names.
- If websites are either not loading or taking an unusually long time to load, it’s a sign that the cached information might be outdated or corrupted.
- Another situation where clearing the DNS cache is necessary is when you face problems with inaccessible websites that work on other devices, or if you notice incorrect page display, where browser pages are not displaying correctly or are missing content.
Addressing these issues by clearing the cache can often resolve these problems and improve your browsing experience.
Following these methods will ensure better browsing performance.
