How to Block Porn Sites on all Web browsers & Network Devices.

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.

BLOCK PORN PORNOGRAPHIC CONTENT

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.

  1. 208.67.222.123
  2. 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:

  1. 199.85.126.20
  2. 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.
