What is DNS Cache?

DNS stands for Domain Name System, which is essentially the phone book of the internet. When you enter a website URL into your browser, such as www.example.com, your device needs to translate that human-readable name into a machine-readable IP address to establish a connection.

In order to improve efficiency and speed up the browsing experience, DNS caching is used. DNS caching involves storing previously accessed domain names and their corresponding IP addresses on your computer or network router for a certain amount of time. This means that when you revisit a website, your device doesn’t have to perform a fresh DNS lookup; instead, it can retrieve the information from the cache.

The DNS cache works as a temporary storage facility, storing the IP address for faster retrieval in the future. It allows your computer to remember the IP addresses of websites you have recently visited without having to request them again from the DNS server. This caching mechanism helps to reduce network traffic and decrease the time it takes to load web pages, making your browsing experience more efficient.

The DNS cache exists at multiple levels. From the local computer level to the internet service provider (ISP) level, different systems and devices maintain their own caches. This allows for quicker access to frequently visited websites and reduces the load on DNS servers.

However, there are situations where it becomes necessary to flush or clear the DNS cache. This is especially true when there are DNS-related issues, such as incorrect or outdated IP address information for a particular website. Clearing the DNS cache can help to resolve these issues and ensure that your device retrieves the most up-to-date information from the DNS server when accessing websites.

Now that you have a basic understanding of DNS cache, let’s explore how to flush and clear the DNS cache in Windows.

Why Clear DNS Cache?

Clearing the DNS cache on your Windows computer can be beneficial in a number of situations. Let’s take a look at a few reasons why you might want to clear your DNS cache:

  1. Resolving DNS-related issues: Sometimes, you may encounter problems accessing certain websites or experiencing slow internet speeds. In these cases, clearing the DNS cache can help resolve DNS-related issues. By flushing the cache and obtaining fresh DNS records, you can eliminate any potential conflicts or errors that might be causing the problem.
  2. Updating DNS information: DNS cache stores IP addresses and domain name mappings. If a website’s IP address has changed recently, your computer may still be holding onto the old information. By clearing the DNS cache, you force your computer to fetch the latest DNS records, ensuring that you are accessing the most up-to-date version of the website.
  3. Fixing website loading errors: At times, you may encounter errors like “DNS_PROBE_FINISHED_NXDOMAIN” or “ERR_CONNECTION_REFUSED” when trying to visit a website. These errors can be caused by outdated or corrupted DNS cache entries. Clearing the DNS cache can help in resolving such errors by refreshing the cache and fetching the correct IP address information for the website.
  4. Securing your online activities: DNS cache poisoning or DNS spoofing attacks can compromise your online security by redirecting your requests to malicious websites. By regularly clearing the DNS cache, you minimize the risk of falling victim to such attacks, as your computer will fetch fresh DNS records from reputable servers.
  5. Troubleshooting network connectivity: If you are experiencing network connectivity issues, clearing the DNS cache can be a useful troubleshooting step. It allows your computer to establish fresh connections with DNS servers, helping to eliminate potential conflicts or misconfigurations that might be causing the problem.

Overall, clearing the DNS cache can help ensure a smoother and more reliable internet browsing experience. It allows your computer to fetch the latest DNS information and resolves DNS-related issues that may be impacting your online activities.

How to Flush DNS Cache in Windows?

Flushing the DNS cache in Windows can be done using various methods. Here are three common methods to flush the DNS cache:

  1. Method 1: Using Command Prompt
  2. 1. Press the Windows key + R to open the Run dialog box.
    2. Type cmd and press Enter to open the Command Prompt.
    3. In the Command Prompt, type ipconfig /flushdns and press Enter.
    4. Wait for the command to execute successfully, and you’ll see a confirmation message.

  3. Method 2: Using Windows PowerShell
  4. 1. Press the Windows key + X and select Windows PowerShell (Admin) to open PowerShell with administrative rights.
    2. In the PowerShell window, type Clear-DnsClientCache and press Enter.
    3. Wait for the command to complete, and you’ll see a confirmation message.

  5. Method 3: Using Windows Network Adapter Settings
  6. 1. Right-click on the Start button and select Network Connections.
    2. In the Network Connections window, right-click on your active network adapter and select Properties.
    3. Scroll down and select Internet Protocol Version 4 (TCP/IPv4).
    4. Click on the Properties button.
    5. In the IPv4 Properties window, click on Advanced.
    6. Go to the DNS tab and click on Clear to clear the DNS cache.
    7. Click OK on all open windows to save the changes.

Choose the method that suits you best and flush the DNS cache to ensure that your computer obtains fresh DNS records for improved browsing performance and to resolve any DNS-related issues that you may be experiencing.

Method 1: Using Command Prompt

One of the simplest and quickest ways to flush the DNS cache in Windows is by using the Command Prompt. Here’s a step-by-step guide:

  1. Press the Windows key + R to open the Run dialog box.
  2. Type cmd and press Enter to open the Command Prompt.
  3. In the Command Prompt window, type the following command:

ipconfig /flushdns

  1. Press Enter to execute the command.
  2. Wait for the command to complete the flushing process. Once completed, you will see a confirmation message that the DNS Resolver Cache has been successfully flushed.

The “ipconfig /flushdns” command instructs your computer to clear the DNS cache, effectively removing any stored DNS records. By doing this, your computer will start with a fresh cache and fetch the latest DNS information when accessing websites.

Keep in mind that flushing the DNS cache does not permanently disable caching. The cache will start accumulating new DNS records as you visit websites. This process helps improve browsing speed by reducing the time taken to resolve domain names to IP addresses.

Flushing the DNS cache using the Command Prompt is a simple yet powerful method to fix issues related to outdated or incorrect DNS information. It can help in resolving DNS-related problems such as slow browsing, difficulty accessing certain websites, or being unable to connect to the internet.

Now that you know how to flush the DNS cache using the Command Prompt, you can easily refresh the DNS records on your Windows computer and enjoy a faster and more reliable browsing experience.

Method 2: Using Windows PowerShell

Another effective method to flush the DNS cache in Windows is by using Windows PowerShell. Here’s a step-by-step guide:

  1. Press the Windows key + X on your keyboard.
