How Do You Unblock a DNS Server?
If you’re experiencing issues accessing certain websites or experiencing slow internet speeds, it could be due to a blocked DNS server. DNS (Domain Name System) is responsible for translating domain names into IP addresses, allowing your computer to connect to websites. When a DNS server is blocked, it can prevent your device from accessing certain websites or cause delays in loading web pages.
Why Would a DNS Server Be Blocked?
There are several reasons why a DNS server may be blocked:
- Internet Service Provider (ISP) Restrictions: Some ISPs may block certain websites or restrict access to specific content.
- Firewall Settings: Your network administrator or firewall settings may have blocked certain DNS servers.
- Malware Infections: Malicious software can alter your DNS settings and redirect your requests to blocked servers.
Methods to Unblock a DNS Server
To regain access to blocked websites and improve your internet connection, you can try the following methods:
Method 1: Change Your DNS Server
You can change your device’s default DNS server to bypass the blocked server and use an alternative one. Here’s how:
- Open the Control Panel and navigate to Network and Internet > Network and Sharing Center.
- Select your active network connection and click on “Properties”.
- In the Properties window, select “Internet Protocol Version 4 (TCP/IPv4)” and click on “Properties”.
- Choose “Use the following DNS server addresses” and enter the preferred DNS server addresses (e.g., Google DNS: 8.8.8 and 8.4.4).
- Click “OK” to save the changes.
- Go to System Preferences and click on “Network”.

Note: You can use public DNS servers like Google DNS, OpenDNS, or Cloudflare.
Method 2: Use a VPN
A VPN (Virtual Private Network) can help bypass internet restrictions by encrypting your connection and routing it through a different server location. By using a VPN, you can access blocked websites and change your IP address, making it appear as if you’re browsing from a different location.
To use a VPN:
- Choose a reputable VPN provider:
- Research and select a VPN provider that offers reliable services with servers in locations you require.
- Subscribe to their service and install their VPN application or configure it manually on your device.

- Launch the VPN application on your device.
- Select a server location that is not blocked or restricted.
- Click “Connect” to establish a secure connection through the chosen server.
Note: Once connected, all your internet traffic will be routed through the VPN server, allowing you to access blocked websites.
Method 3: Check for Malware Infections
If you suspect that malware might be causing DNS blocking issues, it’s essential to scan your device for infections. Here’s what you can do:
- Install reputable antivirus software:
- Research and choose a reliable antivirus program that provides real-time protection against malware.
- Download and install the antivirus software on your device.
- Update the antivirus definitions to ensure it can detect the latest threats.
Note: It’s recommended to use an updated antivirus program from a trusted source.
- Launch the installed antivirus software.
- Select the option to perform a full system scan.>
- Follow the prompts and wait for the scan to complete. >
Note: If any malware is detected during the scan, follow the recommended actions provided by your antivirus software to remove or quarantine it.
Unblocking a DNS server can help resolve issues with accessing blocked websites and improve your overall internet experience. By changing your DNS server, using a VPN, or checking for malware infections, you can overcome restrictions and regain control over your internet access.
Remember to use these methods responsibly and consider any legal or policy implications when bypassing restrictions imposed by your network or internet service provider.
