In this tutorial, we will learn how to block Facebook using a DNS server. This can be useful if you want to restrict access to Facebook on your network for various reasons such as productivity or security concerns. By blocking Facebook at the DNS level, you can prevent users from accessing the website without having to rely on individual device settings.
What is a DNS Server?
A DNS server stands for Domain Name System server. It is responsible for translating domain names (e.g., www.facebook.com) into IP addresses (e., 220.127.116.11). When you type a URL into your web browser, the DNS server is queried to find the corresponding IP address so that your browser can connect to the website.
Why Block Facebook at the DNS Level?
Blocking Facebook at the DNS level has some advantages over other methods like using firewall rules or browser extensions:
- Simplicity: Blocking Facebook at the DNS level is relatively simple and does not require complex configurations.
- Network-Wide Blocking: By blocking Facebook at the DNS server, you can ensure that all devices connected to your network are unable to access it.
- Difficult to Bypass: Compared to other methods, blocking at the DNS level is more difficult for users to bypass as it affects all devices on the network.
Steps to Block Facebook Using Your DNS Server
To block Facebook using your DNS server, follow these steps:
Step 1: Access Your Router’s Configuration
The first step is to access your router’s configuration page. Open a web browser and enter your router’s IP address in the address bar. This IP address is typically mentioned in the router’s documentation or can be found by running the ipconfig command in the command prompt.
Step 2: Find the DNS Settings
Once you have accessed your router’s configuration page, navigate to the DNS settings. The location of these settings may vary depending on your router’s manufacturer and model.
Look for options related to “DNS” or “DNS Server. “
Step 3: Configure DNS Blocking
In the DNS settings, you will find options to configure custom DNS servers. Usually, these options are labeled as “Primary DNS” and “Secondary DNS.”
Enter the IP address of a DNS server that blocks Facebook. Some popular options include:
- OpenDNS: Primary DNS: 18.104.22.168, Secondary DNS: 208.220.123
- Norton ConnectSafe: Primary DNS: 22.214.171.124, Secondary DNS: 199.127.10
Note that these are just a few examples, and you can use any other suitable DNS servers that offer blocking functionality.
Step 4: Save and Apply Changes
After configuring the custom DNS servers, save your changes by clicking on the “Save” or “Apply” button (the label may vary depending on your router’s interface). Allow your router a moment to apply the changes.
Verifying Facebook Blocking
To verify whether Facebook blocking is working correctly, try accessing Facebook from a device connected to your network (e., a computer or smartphone). If everything is set up correctly, you should see an error message indicating that the website cannot be reached.
Congratulations! You have successfully blocked Facebook using your DNS server.
Blocking Facebook at the DNS level is an effective way to restrict access to the website on your network. By following the steps outlined in this tutorial, you can easily configure your DNS server to block Facebook and ensure that users connected to your network are unable to access it.
Remember that DNS blocking is just one method of restricting access, and determined users may find ways to bypass it. For more robust control, consider combining DNS blocking with other methods like firewall rules or content filtering applications.
