The MetaCert DNS is the world’s most sophisticated method of blocking pornography without blocking access to innocent websites. It blocks over 700 million pages of sexually explicit content – or 32+ billion URLs. The biggest problem that MetaCert solves is the issue with ‘over-blocking on mass scale. MetaCert’s error rate of false positives is less than 0.3% – in simple terms, we don’t block innocent websites like every other service provider.
Disputed domains are reviewed and where necessary, revised within two hours on average. Try contact Norton, McAfee or Kasperskey about an innocent website blocked by their products. We reached out to some of them about their blocking of our family safety iPad browser website and we have yet to hear back.
For most of our customers today, the MetaCert Primary DNS is 126.96.36.199 and secondary DNS is 188.8.131.52. Customers based in Europe should switch these around.
Our DNS service is free for home use, but public wifi providers, ISPs and companies should contact our team should they wish to use our DNS service in their workplace, or sell it as a service to customers. Please contact our VP of Partnership, Sheetal Walsh for more information
MetaCert DNS can be used by anyone, anywhere in the world. It is the world’s best solution for blocking pornography on the web (MetaCert’s definition can be found here), blocking more than 626 million pages and counting (our crawler and classification system is busy working 24×7). What’s important, is that the MetaCert DNS does not block sites it shouldn’t, unlike systems based on keyword blocking.
The MetaCert DNS can be used by parents/guardians at home. In the coming weeks we are going to develop an easy-to-use software application that will automatically configure your computer with the necessary change. The application will allow you to turn the blocker on and off. You will also be able to manually include any other website that you wish to block, just for your computer.
Until we build this slick application, you must make the change manually. It also means that you will not be abele to switch the blocker off. To switch the blocker off you will need to revert back to your old DNS. We have provided detailed instructions below.
The MetaCert DNS can be used by companies that wish to block pornography in order to mitigate the risk of lawsuits from staff, or reduce the likelihood of viruses being downloaded onto office computers. It can be used by public wifi hotspot providers at airports, coffee houses and hotels. And it can be used by ISPs, router manufacturers, mobile operators, schools and libraries.
Before you change your DNS settings to use MetaCert’s DNS, be sure to write down the current server addresses or settings on a piece of paper. It is very important that you keep these numbers for backup purposes, in case you need to revert to them at any time.
After changing your settings, if you encounter a problem and cannot connect to the Internet, please get in touch with our support team using this form – select “Contact support” on the right.

Every router uses a different user interface for configuring DNS server settings; we provide only a generic procedure below. For more information, please consult your router documentation.
Note: Some ISPs hard-code their DNS servers into the equipment they provide; if you are using such a device, you will not be able to configure it to use MetaCert DNS. Instead, you can configure each of the computers connected to the router, as described above.
To change your settings on a router:
DNS servers are typically specified under advanced wi-fi settings. However, as every mobile device uses a different user interface for configuring DNS server settings, we provide only a generic procedure below. For more information, please consult your mobile provider’s documentation.

If you want to report a problem to the MetaCert, please copy and paste the results of the commands in your ticket and use this form to report it. Please be as descriptive as you can about the problems you are experience and make sure to tell us what operating system you are using.
If you had not previously configured any customized DNS servers, to switch back to your old settings, in the window in which you specified the MetaCert IP address, select the option to enable obtaining DNS server addresses automatically, and/or delete the MetaCert IP addresses. This will revert your settings to using your ISP’s default servers.
If you need to manually specify any addresses, use the procedures above to specify the old IP addresses.
If necessary, restart your system.
