How to Check If My DNS Is Working Properly: A Quick Guide

The Domain Name System (DNS) is a critical component of the internet infrastructure that allows us to access websites and other internet services using easy-to-remember domain names. However, just like any other technology, DNS can have issues that can disrupt our online experience. That’s why it is essential to regularly check if your DNS is working properly to ensure uninterrupted access to the internet.

In this quick guide, we will walk you through the steps to check if your DNS is functioning correctly. Whether you are experiencing slow internet speeds, intermittent connectivity issues, or simply want to ensure the reliability of your DNS, this guide will provide you with the necessary tools and techniques to diagnose and troubleshoot any DNS-related problems. So, let’s dive in and learn how to check if your DNS is working properly.

What Is DNS And Why Is It Important?

DNS, or Domain Name System, is a critical component of the internet that translates human-readable domain names into IP addresses. It acts as a phonebook for the internet, allowing users to access websites simply by typing in domain names such as, instead of having to remember the corresponding IP address like

DNS plays a pivotal role in ensuring smooth and efficient internet connectivity. Without DNS, we would need to remember the IP addresses of every domain we wanted to visit, which would be both impractical and inconvenient. It simplifies the process by mapping easy-to-remember domain names to their respective IP addresses.

Ensuring that your DNS is working properly is crucial for seamless browsing and accessing online services. If DNS issues arise, it can lead to problems like slow internet speeds, website inaccessibility, email delivery failures, and overall connectivity disruptions. By understanding DNS and its significance, you can troubleshoot and resolve any issues that may arise, ensuring a smooth online experience.

Common Signs That Indicate DNS Issues

If you are experiencing difficulties accessing websites, it might be due to DNS issues. DNS (Domain Name System) is responsible for converting human-friendly domain names into IP addresses that computers understand. To identify and resolve DNS problems, it is crucial to be aware of the common signs that indicate such issues.

One common sign of DNS problems is slow or intermittent internet connectivity. If you frequently encounter difficulties in connecting to websites or experience slow loading times, it could be an indication of DNS issues. Additionally, if you receive error messages like “DNS server not responding” or “server DNS address could not be found,” it is highly likely that your DNS settings require attention.

Another sign of DNS issues is being redirected to incorrect websites or receiving search results unrelated to your queries. This could be caused by incorrect DNS configurations, malware, or even a compromised router.

To ensure your internet connection works smoothly, it is important to address DNS issues promptly. Understanding the common signs of DNS problems will help you identify and resolve them effectively, ensuring a seamless browsing experience.

Step-by-step Guide To Check DNS Settings On Windows

When it comes to troubleshooting DNS issues, Windows users may find themselves in need of verifying their DNS settings. This step-by-step guide will help you check if your DNS settings are working properly on your Windows computer.

1. Open the Control Panel: Click on the “Start” button, search for Control Panel, and open it.

2. Network and Internet Settings: Inside the Control Panel, click on “Network and Internet” and then go to “Network and Sharing Center.”

3. Change adapter settings: On the left-hand side of the screen, you will find an option that says “Change adapter settings.” Click on it.

4. Choose active network interface: Look for the network interface you are currently using (e.g., Wi-Fi or Ethernet), right-click on it, and select “Properties.”

5. Internet Protocol Version 4 (TCP/IPv4): Locate the following entry in the list of items and double-click on it. This will open a new window.

6. Verify DNS settings: In the new window, make sure that the options “Obtain an IP address automatically” and “Obtain DNS server address automatically” are selected. If they are not, make the necessary changes and save them.

Verifying and adjusting your DNS settings using this step-by-step guide can help you ensure that your Windows computer is using the correct DNS servers for a smooth and reliable internet browsing experience.

How To Verify DNS Functionality On Mac Computers

Mac computers have built-in tools that allow you to easily verify the functionality of your DNS settings. Here’s a step-by-step guide to help you ensure that your DNS is working properly on your Mac:

1. Open the Terminal application on your Mac. You can do this by searching for Terminal in the Spotlight search or navigating to Applications > Utilities > Terminal.

2. Once the Terminal window opens, type in the following command and press Enter:
Replace “” with the domain name you want to check.

3. The Terminal will display information about the DNS server used for the lookup and the corresponding IP address. If you receive a valid IP address, it indicates that the DNS resolution is working correctly.

4. Additionally, you can use the “dig” command in the Terminal to perform more advanced DNS queries. For example:
This command will provide you with detailed information about the DNS records associated with the domain.

By using these built-in tools on your Mac, you can easily verify the functionality of your DNS and ensure that it is working properly.

Troubleshooting DNS Problems On Mobile Devices

Mobile devices, such as smartphones and tablets, have become a primary means of accessing the internet. However, just like any other device, they can encounter DNS problems that hinder their ability to connect to websites and online services.

To troubleshoot DNS issues on mobile devices, start by checking your Wi-Fi or mobile data connection. Ensure that you have a stable and reliable internet connection. If the issue persists, try the following steps:

1. Restart your device: A simple restart can often fix minor DNS problems.
2. Clear DNS cache: Clearing the DNS cache can resolve issues caused by outdated or corrupted DNS information. Open the Settings app, find the Network or Wi-Fi settings, and look for an option to clear the DNS cache.
3. Change DNS settings: You can manually set the DNS servers your device uses. Look for the DNS settings in the Wi-Fi or Network settings and enter Google DNS ( and or any other reliable DNS server.
4. Disable any VPN or proxy: Virtual private networks (VPNs) or proxies can sometimes interfere with DNS resolution. Disable them temporarily to see if that resolves the issue.
5. Contact your mobile network provider: If the problem persists, reach out to your mobile network provider’s customer support for assistance. They may be able to provide specific troubleshooting steps or investigate network-related issues.

By following these troubleshooting steps, you can improve your chances of resolving DNS problems on mobile devices and regain full access to the internet.

Advanced Techniques To Diagnose And Resolve Complex DNS Problems

In some cases, simple troubleshooting steps may not be enough to resolve DNS issues. This is when advanced techniques come into play. These techniques are targeted at diagnosing and resolving more complex DNS problems that may require a deeper understanding of networking and domain name systems.

One powerful tool that can aid in diagnosing DNS issues is the command-line utility called nslookup. Nslookup can be used to query DNS servers and retrieve detailed information about domain names, IP addresses, mail servers, and more. By using nslookup, you can test DNS resolution, check for DNS errors, and troubleshoot DNS misconfigurations.

Another useful tool for diagnosing DNS problems is traceroute. Traceroute allows you to track the path that packets take to reach a destination IP address, revealing any network connectivity issues or delays along the way. By analyzing the traceroute output, you may identify problematic routers or network segments that could be causing DNS resolution problems.

Additionally, it is important to keep your DNS software and server configurations up to date. Check for available updates and patches for your DNS software and apply them as necessary. Regularly reviewing and adjusting your DNS server configurations can ensure that they are optimized for performance and security.

By utilizing these advanced techniques and tools, you can effectively diagnose and resolve complex DNS problems, ensuring that your DNS is working properly and your online activities run smoothly.
