Understanding DNS and Its Importance
Domain Name System (DNS) is often referred to as the “phonebook” of the internet. It translates human-friendly domain names, like www.example.com, into machine-readable IP addresses, like 192.0.2.1. This process is essential for navigating the internet successfully because, without it, you’d need to memorize complex numerical addresses to reach websites.
AdGuard DNS aims to provide users with a fast and secure DNS service that blocks unwanted ads and trackers. However, many users can face issues where dns.adguard.com is not working, leading to frustration and potential privacy concerns. Understanding how DNS functions and identifying the underlying problems can help you maintain a seamless online experience.
Common Reasons for dns.adguard.com Not Working
When you experience issues with dns.adguard.com, it can stem from several factors. Here are some prevalent causes:
1. Configuration Errors
If your device or network is not configured correctly to use AdGuard DNS, you might run into connection issues. Configuration mistakes often include incorrect DNS server addresses or improper network settings.
2. Internet Connectivity Issues
At times, the problem might be with your internet connection rather than AdGuard itself. If your network is down or experiencing instability, DNS queries to any server will be affected.
3. ISP-Level Restrictions
Some Internet Service Providers (ISPs) may block access to third-party DNS servers like AdGuard. If you suspect this is a cause, testing another DNS service would be helpful.
4. Firewall or Antivirus Interference
Firewall and antivirus software can sometimes mistakenly block legitimate DNS queries or traffic to dns.adguard.com. Configured incorrectly, they can obstruct necessary connections to keep your system secure.
5. DNS Cache Issues
Your device stores DNS cache to speed up the loading of frequently accessed websites. However, if the cache becomes stale or corrupted, it can lead to issues. Regular clearing of the cache is essential for smooth browsing.
Troubleshooting Steps for dns.adguard.com Issues
If you encounter issues with dns.adguard.com, follow these detailed troubleshooting steps to potentially resolve the problem.
Step 1: Check Your Internet Connection
Before diving into DNS settings, ensure your internet connection is stable. You can perform a simple test by trying to access other websites. If they load correctly but dns.adguard.com does not, continue with the next steps.

Open Terminal and enter the following command:
sudo killall -HUP mDNSResponder
Step 4: Disable Firewall/Antivirus Temporarily
To check if your firewall or antivirus software is causing the problem, temporarily disable them and see if dns.adguard.com works. If you find this is the cause, consider adding an exception for AdGuard in your security software settings.
Step 5: Test Different DNS Providers
If dns.adguard.com remains unresponsive, testing another DNS service can help you determine if the issue lies with AdGuard or your network setup. Consider using Google DNS (8.8.8.8 and 8.8.4.4) or Cloudflare DNS (1.1.1.1) temporarily.
For example, to switch to Google DNS:
- Follow the instructions mentioned in Step 2, but enter the Google DNS addresses instead.

What is DNS.adguard.com and how does it work?
DNS.adguard.com is a DNS service provided by AdGuard, designed to enhance user privacy while browsing the internet. It blocks ads and trackers at the DNS level, which can improve loading times and protect against unwanted content. By routing your DNS queries through their servers, AdGuard helps ensure a clean and faster browsing experience.
When a user attempts to access a website, their device sends a DNS query to resolve the site’s domain name into an IP address. DNS.adguard.com responds to these queries with filtered results, preventing access to malicious sites or blocking ads as specified in the user’s preferences. This results in a smoother browsing experience with less clutter.
Why is DNS.adguard.com not responding?
There could be several reasons why DNS.adguard.com is not responding. Network issues such as regional outages, ISP problems, or incorrect device configurations can lead to unresponsive DNS queries.
