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.

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.
