HubSpot Guide: How to Flush Your DNS Cache

Following a HubSpot style of clear, actionable instruction, this guide explains how to flush your DNS cache on Windows, macOS, and common browsers so you can quickly fix loading errors, connection problems, and outdated page issues.

When your DNS cache stores old or corrupted records, your device may struggle to reach the right server, even when your internet connection seems fine. Clearing these records forces your system to look up fresh information and often restores normal browsing in seconds.

What Is DNS Cache and Why It Matters

DNS, or Domain Name System, works like the internet's phone book. Instead of you memorizing long IP addresses, DNS turns easy-to-remember domain names into the numerical addresses computers use to reach websites.

Your device stores these lookups locally in a DNS cache. Over time, this cache can become outdated or corrupted, leading to problems such as:

  • Websites not loading even though they are online
  • Pages loading the wrong version of a site
  • Intermittent connection or redirect errors
  • Issues after changing DNS settings or moving a site to a new host

Flushing the cache deletes these stored records so your system can retrieve updated DNS information from authoritative servers.

Before You Flush DNS in a HubSpot-Style Workflow

Before jumping into the step-by-step instructions, it helps to confirm that DNS is the real issue and not something else, like general network failure. A process-driven, HubSpot-inspired troubleshooting workflow usually includes:

  • Checking your connection – Confirm Wi-Fi or Ethernet is working by loading several unrelated websites.
  • Testing on another device – If another device on the same network can load the site, the issue may be local DNS cache.
  • Restarting your router or modem – Power-cycling your equipment can resolve some DNS delivery issues.

If a single device continues to have issues while others work fine, flushing the DNS cache is a logical next step.

HubSpot-Style Steps: Flush DNS on Windows

On Windows, flushing DNS is done through the Command Prompt. These steps match the systematic approach you see in many HubSpot technical tutorials.

HubSpot Method: Flush DNS on Windows 10 and 11

  1. Open Command Prompt as Administrator
    • Click the Start menu.
    • Type cmd or Command Prompt.
    • Right-click Command Prompt and choose Run as administrator.
  2. Run the DNS Flush Command
    • In the Command Prompt window, type:
      ipconfig /flushdns
    • Press Enter.
  3. Confirm the DNS Cache Is Cleared
    • You should see a message like: Successfully flushed the DNS Resolver Cache.

Once complete, close Command Prompt and try reloading the problem website.

Additional Windows DNS Commands

If you are working through a more advanced, HubSpot-like troubleshooting checklist, you may also use:

  • ipconfig /registerdns – Renews DNS registration.
  • ipconfig /release and ipconfig /renew – Refreshes your IP address and network configuration.

These extra commands are optional but useful when you suspect deeper network or DNS configuration problems.

HubSpot Guide: Flush DNS Cache on macOS

On macOS, you use the Terminal app to flush the DNS cache. Commands vary slightly by version, but the basic process is consistent.

Step-by-Step for macOS Monterey, Ventura, and Later

  1. Open Terminal
    • Click the Launchpad icon in the Dock.
    • Type Terminal in the search bar and open it.
  2. Enter the DNS Flush Command
    • Type the following command:
      sudo dscacheutil -flushcache; sudo killall -HUP mDNSResponder
    • Press Enter.
  3. Authenticate
    • Enter your administrator password when prompted.
    • Press Enter again.

You will not see a success message, but the command runs silently and clears your DNS cache.

Other macOS Versions

On some older versions of macOS, the command is slightly different, but the HubSpot-style process is the same: open Terminal, run the relevant flush command, then test your connection again.

HubSpot Tutorial Style: Clear DNS in Browsers

Sometimes issues live inside the browser rather than the operating system. Many modern browsers maintain their own DNS cache. Clearing it is simple and fits well with a HubSpot-inspired, stepwise diagnostic flow.

Chrome: Clear DNS Cache

  1. Open Google Chrome.
  2. In the address bar, visit:
    chrome://net-internals/#dns
  3. Click Clear host cache.

After clearing the cache, close and reopen Chrome for best results.

Edge and Other Chromium-Based Browsers

Microsoft Edge and many Chromium-based browsers use the same DNS internals page:

  1. Open the browser.
  2. Go to edge://net-internals/#dns (or similar URL, depending on the browser).
  3. Click Clear host cache.

Safari and Firefox

Safari and Firefox do not always expose a dedicated DNS cache screen, but you can often clear DNS-related data by:

  • Clearing browsing history
  • Removing cached files
  • Restarting the browser after a system-level DNS flush

Combining OS and Browser Steps in a HubSpot Workflow

A reliable, HubSpot-aligned troubleshooting routine often includes both system and browser actions:

  1. Flush DNS at the operating system level (Windows or macOS).
  2. Clear the browser DNS cache if your browser supports it.
  3. Close and reopen the browser.
  4. Test the problematic site in an incognito or private window.

If the issue persists, try accessing the site from a mobile device on cellular data to rule out broader network or ISP issues.

When Flushing DNS May Not Be Enough

Flushing DNS is a powerful fix, but some problems require additional steps. Drawing from a HubSpot-style, holistic approach, consider the following if issues remain:

  • Check DNS server settings – Try switching to public DNS servers like Google DNS or Cloudflare.
  • Scan for malware – Malicious software can alter DNS behavior.
  • Inspect VPN or proxy configurations – Temporary disablement can reveal conflicts.
  • Look for site-level issues – The website itself may be down or misconfigured.
