There are various ways to try and stop inappropriate online content like pornographic material being accessible to children, one is to install parental control software. The software can be effective at blocking this type of material up to a point but can be messed with or bypassed. Another option which doesn’t need any software installed on your computer is filtering content through the Domain Name System (DNS).
DNS is a set of online servers that translate standard website names into their corresponding IP address which the browser needs to show the website (for raymond.cc it’s 220.127.116.11). It’s like a huge Windows HOSTS file with billions of entries. ISPs generally use their own DNS servers which will be the default for all devices using your internet connection. However, they are not always that fast, private or secure.
There are many third party DNS services that can filter out specific website addresses, like ad hosting, malicious content, illegal content and of course, adult or pornographic content. Here we show you eight free DNS services that offer adult or pornographic content blocking as standard. All you have to do is add the DNS addresses to your Windows network properties. Instructions are supplied on the specific websites if you don’t know how to do it. IPv6 addresses are also included for more advanced users.
1. OpenDNS Family Shield
OpenDNS was one of the first to offer free DNS servers with adult content filtering back in 2010. It is possible to create a free account and customize the DNS service with extra filters (such as blocking social networks, P2P or gambling), domain blocking and even creating a custom block page. However, it’s not a requirement and you can just set and forget using the addresses provided.
OpenDNS has two free DNS services, Family Shield and Home. Family Shield is pre configured to filter out adult content by default and will be enough if that’s all you want. To block even more, such as illegal activity, social networking or custom domains, create an account and set up custom filtering. This works with both Home and Family Shield. The process looks complicated but there are many guides on the internet to help.
