MetaCert DNS for family safety

The MetaCert DNSis 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.

MetaCert Family Safe DNS

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.

For consumers

The MetaCert DNS can be used by parents/guardians at home. In the coming months 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.

For enterprise

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

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.

Instructions on how to change your DNS

Example: Changing DNS server settings on Windows 7

  1. Go the Control Panel.
  2. Click Network and Internet, then Network and Sharing Center, and click Change adapter settings.
  3. Select the connection for which you want to configure MetaCert DNS. For example: To change the settings for an Ethernet connection, right-click Local Area Connection, and click Properties. To change the settings for a wireless connection, right-click Wireless Network Connection, and click Properties. If you are prompted for an administrator password or confirmation, type the password or provide confirmation.
  4. Select the Networking tab. Under This connection uses the following items, select Internet Protocol Version 4 (TCP/IPv4) and then click Properties.
  5. Click Advanced and select the DNS tab. If there are any DNS server IP addresses listed there, write them down for future reference, and remove them from this window.
  6. Click OK.
  7. Select Use the following DNS server addresses. If there are any IP addresses listed in the Preferred DNS server or Alternate DNS server, write them down for future reference.
  8. Replace the Preferred DNS address with the IP addresses of the MetaCert DNS servers; 184.169.223.35
  9. Restart the connection you selected in step 3.
  10. Test that your setup is working correctly; see Testing your new settings below.
  11. Repeat the procedure for additional network connections you want to change.

Mac OS X

DNS settings are specified in the Network window.

Example: Changing DNS server settings on Mac OS 10.5

  1. From the Apple menu, click System Preferences, then click Network.
  2. If the lock icon in the lower left-hand corner of the window is locked, click the icon to make changes, and when prompted to authenticate, enter your password.
  3. Select the connection for which you want to configure MetaCert DNS. For example: To change the settings for an Ethernet connection, select Built-In Ethernet, and click Advanced. To change the settings for a wireless connection, select Airport, and click Advanced.
  4. Select the DNS tab.
  5. Click + to replace the first listed address with, 184.169.223.35
  6. Click Apply and OK.
  7. Test that your setup is working correctly; see Testing your new settings below.
  8. Repeat the procedure for additional network connections you want to change.

Router

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:

  1. In your browser, enter the IP address to access the router’s administration console.
  2. When prompted, enter the password to access network settings.
  3. Find the screen in which DNS server settings are specified.
  4. If there are IP addresses specified in the fields for the primary and seconday DNS servers, write them down for future reference.
  5. Replace the primary address with 184.169.223.35
  6. Save and exit.
  7. Restart your browser.
  8. Test that your setup is working correctly; see Testing your new settings below.

Mobile or other devices

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.

To change your settings on a mobile device:

  1. Go to the screen in which wi-fi settings are specified.
  2. Find the screen in which DNS server settings are specified.
  3. If there are IP addresses specified in the fields for the primary and seconday DNS servers, write them down for future reference.
  4. Replace the primary DNS with 184.169.223.35
  5. Save and exit.
  6. Test that your setup is working correctly; see Testing your new settings below.

Testing your new settings

To test that the MetaCert DNS resolver is working:

  1. From your browser, type in a hostname (such as http://metacert.com). If it resolves correctly, bookmark the page, and try accessing the page from the bookmark. If both of these tests work, everything is working correctly. If not, go to step 2.
  2. From your browser, type in a fixed IP address. You can use http://18.62.0.96/ (which points to the website http://www.eecs.mit.edu/) as the URL. If this works correctly, bookmark the page, and try accessing the page from the bookmark. If these tests work (but step 1 fails), then there is a problem with your DNS configuration; check the steps above to make sure you have configured everything correctly. If these tests do not work, go to step 3.
  3. Roll back the DNS changes you made and run the tests again. If the tests still do not work, then there is a problem with your network settings; contact your ISP or network administrator for assistance.

To test that the MetaCert family safety control is working:

From your browser, type in http://test3.metacert.com. If you get a warning page that says it may contain inappropriate content, you know it’s working.

Reporting issues

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.

Switching back to your old DNS settings

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.

If you like what you see, please like us on Facebook and tell your friends and family to try out our service. Our vision is to help improve online family safety across every device with internet access. Anything you can do to help us in that quest will be greatly appreciated.

    @Or I assume you’re using our iPad browser? If you are, then I’m afraid there’s not a lot you can do apart from restore. This is the same when you forget your passcode to Apple settings. We have just released an update that replaces the pincode with a username and password – so we can soon add account syncing.
