In this tutorial I 'll show you the safest way to block the access to porn sites and harmful content on all browsers in all or in specific devices on your home network.
Internet is a huge library of all types of content: useful, informative, dangerous, pornographic, etc. This makes its usage risky for children when parents don't take the appropriate actions to prevent dangerous adult sites from appearing to every Internet connected device.
One solution to block the dangerous and pornographic content is to install a parental control software or a blocking plugin (extension) on every computer and every mobile device on the network. But most software and plugins can be easily bypassed or disabled. So, we must proceed one step ahead and apply an overall solution for kids so that our protection will not get easy bypassed. To accomplish this task we 'll use the Domain Name System.
The Domain Name System (DNS) is used to resolve hostnames into machine-readable IP addresses for any device or service connected to the Internet or to a private network.
In fact, DNS memorizes and translates Domain Names (e.g. www.microsoft.com) to numerical IP Addresses (e.g. 191.239.213.177). For example: when you want to connect to a website (e.g.www.microsoft.com) your computer "asks" the default DNS server (commonly provided by your ISP), for the numerical IP Address of this website. The DNS server "answers" this request by providing the numerical IP Address of the site (e.g. 191.239.213.177) to your computer.
How to Block the Access to Porn Sites on all Web browsers & Network Devices.
In this article we present two (2) free reliable DNS filtering services and the way to use them in order to prevent the appearance of dangerous content on your Web browser and Network Device(s).
Open DNS
Open DNS is a DNS security service and company (was bought by Cisco in August 2015), which provides phishing and content filtering protection to its customers. Open DNS offers a free DNS content filtering service, called FamilyShield for home and personal use. During our tests we found Open DNS Family Shield as a very reliable and fast content filtering service.
In order to use the Open DNS FamilyShield service for your protection, you have to use the following DNS servers on your router (for global protection) or in every Internet connected device.
- 208.67.222.123
- 208.67.220.123
Norton ConnectSafe
Symantec's Norton ConnectSafe is the second reliable free DNS service that we suggest to prevent the access to adult and pornographic content. During our tests, this content filtering service works great and blocked all requested porn sites, but it was very slow in its response.
If you want to use Norton ConnectSafe DNS service to protect your family from unsafe sites, then you have to specify the following DNS servers on your router (global protection) or in every computer or mobile device that you want to protect:
- 199.85.126.20
- 199.85.127.20
How to specify and use DNS content filtering servers on devices:
Below you can find detailed instructions on how you can block Porn & Harmful sites on all or specific network devices.
Block the Access to Porn Sites on all Web browsers (For all Network Computers & Devices).
Router Configuration: Global protection.
By applying the following steps, you 'll prevent all computers and mobile devices on your home network to access unsafe and dangerous sites from any Web browser (Internet Explorer, Firefox, Chrome, Safari, etc.).
1. Open your Internet browser & type your router's IP address * in the address bar. (e.g. 192.168.1.1). Hit Enter.
* Note: To find your router's IP address in Windows:
- Go to Control Panel > Network and Sharing Center.
- Click Adapter Settings on the left.
- Double click to open the active Network Connection (e.g. the "Local Area Connection").
- Click Details. Your router's IP address is the number displayed next to IPv4 Default Gateway. In this example it is "192.168.1.1"
2. At 'Login Screen' enter your credentials to access the router's web interface.
3. Locate the DNS server settings.
4. Write down (for safety reasons) the IP Address numbers that are currently listed next to "Primary DNS Server" & "Secondary DNS server" boxes (if listed).
4. Then delete the current DNS IP Addresses from all boxes and then type the new DNS IP Server addresses that you want to use for content filtering.
(In this screenshot we have used OpenDNS server addresses for content filtering.)
5. Save settings and logout from your router's configuration web interface.
Device's DNS Configuration – Single Protection.
If you want to prevent only specific devices from accessing unsafe content, then you have to change DNS servers only at the specific device(s) that you want to protect. Detailed instructions according to your device's OS are given below:
Block the Access to Porn Sites on a Windows PC.
Windows DNS Configuration.

4. Select the 'Internet Protocol Version 4 (TCP/IPv4)' and click Properties.
5. Select "Use the following DNS server addresses" and type the new DNS IP Server addresses that you want to use for content filtering.
6. Press OK and close network properties.
Block the Access to Porn Sites on a MAC PC.
MAC OSX DNS Configuration.
To prevent the access to pornographic and malicious material in all browsers on a MAC computer:
1. Go to System Preferences.

3. Select the Active connection on the left and then type the new DNS Server IP Addresses that you want to use for content filtering, separated by comma. (e.g. 199.85.126.20, 199.85.127.20).
(In this screenshot we have used Norton ConnectSafe server addresses for content filtering.)
4. Click Apply and close Network settings.
Block the Access to Porn Sites on Android.
Android DNS Configuration.
To prevent the access to pornographic content on your Android device:
1. Open Android Settings.
2. Tap Wi-Fi.
3. Tap and long press the Network that you 're connected to. Choose Modify network config.
4. Check Show advanced options.
5. Change the IP Settings from DHCP to Static.
6. At DNS1 & DNS 2 fields type the new DNS servers that you want to use for device protection and tap Save.
7. Close Wi-Fi settings.
That's it!
