Clearing the DNS (Domain Name System) cache can resolve issues related to outdated or incorrect DNS records stored in Chrome. This guide explains how to clear DNS cache using Chrome’s internal tools accessed through chrome://net-internals/#dns, offering steps, benefits, and best practices for maintaining optimal browsing performance.

Understanding DNS Cache

What is DNS Cache?

DNS cache stores recent DNS lookup results locally on your device, speeding up subsequent access to websites by avoiding repeated DNS queries. However, outdated or incorrect entries in the DNS cache can lead to connectivity issues or slow browsing speeds.

Why Clear DNS Cache?

  • Resolve Connectivity Issues: Clearing DNS cache can fix problems where websites fail to load due to outdated DNS records.
  • Refresh DNS Data: Ensure accurate DNS resolution by removing stale entries from the cache.

  1. Open Chrome Browser: Launch Google Chrome on your desktop.
  2. Navigate to Net-Internals: Type chrome://net-internals/#dns in the address bar and press Enter.
