We are often asked how you can set up a computer or mobile device so any inappropriate adult sites are automatically blocked. While you can purchase software that does it, it is really easy to set things up for free using OpenDNS, which is a free internet security service. The entire process just takes a couple minutes to complete. Please note that nothing is 100% perfect, so we still suggest always having adult supervision around when kids are online.
iPad, iPhone and Android Mobile Devices
1.) Go to your Settings section and tap on your WiFi icon. Please note that these instructions will only work with WiFi. If you plan on using a wireless mobile carrier for access, they will not apply to it. With a tablet or phone on a wireless carrier, the best solution would be to set Parental Controls that block web browsers and download and install the free KidzSearch App which will filter adult content search results and block websites from being directly entered. At the very least, just use a SafeSearch website, such as KidzSearch.com
2.) Click on the details section of your wireless provider. On an iPhone you will see an ‘i’ with a circle around it. You want to edit the wireless settings for your current provider by tapping on the ‘i’, or whatever links gets you to the DNS editor.
3.) The next step is what will give you automated filtering and it involves changing the DNS settings. Before you change it, be sure to write down what is currently set so you can go back to regular non-filtered settings if needed. It will be a set of numbers like “18.104.22.168”
4.) Click on the DNS numbers and erase them by back spacing. Next, add a DNS provider that filters websites. We like OpenDNS. You need to use the following for OpenDNS.
Enter it exactly as shown above. Double check your entry and click return/done when finished.
On an Android Device, including the Kindle Fire, you will need to go to settings / Wi-Fi and then press and hold your current connection for a few seconds. Select Modify Network and be sure Show Advanced Options is selected. Change the IP settings from DHCP to Static. Next, page down the list of options until you see DNS 1 and DNS 2. This is where you would change it to use Open DNS (22.214.171.124, 126.96.36.199).
You now have OpenDNS installed which will keep your mobile device safe by blocking any adult sites. You should still use KidzSearch.com as your search engine since you need to know what safe sites are available that won’t get blocked by OpenDNS. However, with OpenDNS installed, you don’t need to worry about your child typing in a porn address by mistake or otherwise.
For added safety, we strongly suggest also using Parental Settings and blocking all web browsers and unapproved App downloads. You can then use the Free KidzSearch App as your tablet or mobile phone browser, which will prevent outside website links from being entered directly (sites can only be searched using the SafeSearch engine provided). Installing the free KidzSearch App just takes a minute and there is no setup or signing up for anything. It will make your setup a lot safer. In addition, as mentioned earlier, OpenDNS settings will not work if the tablet or phone is being used on a 3G/4G outside signal, such as if you are away from your wireless home router. The KidzSearch App will give you backup safety when this happens. It is also a lot simpler in case your are not able to configure OpenDNS on your device, even for home use. However, we still suggest always using OpenDNS if possible for added safety.
More detailed instructions for using OpenDNS are available from the OpenDNS Website that covers just about any mobile device, but the process is all the same in that you only need to change the DNS provider. Be sure you use the most updated DNS settings (188.8.131.52, 184.108.40.206) worked best for us, but it could change in the future.
Alternative DNS Services to Block Porn Sites
The following services can also be used to block adult content. It is often just a matter of personal preference when choosing what is best for you. The procedure is exactly the same as described above, but uses different DNS IP numbers.
Primary DNS Server: 220.127.116.11
Secondary DNS Server: 18.104.22.168
Primary DNS Server: 22.214.171.124
Secondary DNS Server: 126.96.36.199
Primary DNS Server: 188.8.131.52
Secondary DNS Server: 184.108.40.206
Primary DNS Server: 220.127.116.11
Secondary DNS Server: 18.104.22.168
Locking Your Settings
For extra security, there are numerous apps that will lock your settings so a password is required to make a change to them, such as Mobile Fence. This will keep a more adventurous child from changing the DNS settings. Some of these apps also claim to block adult websites, but based on some testing we did, they were just not nearly good enough in our opinion and still required using the OpenDNS Server filtering to properly block adult content.
We also strongly suggest protecting what apps can be downloaded. Just click on the settings menu when in the app store and select Content Filtering. You can then set it to the appropriate level, such as only showing Everyone rated apps. Requiring a password to make any purchases is also a very good idea too and can be activated via the settings menu.
Making your Desktop or Laptop Safe
This is very similar to the change made for safe mobile browsing. You need to change the DNS settings. On Windows 8 go to Control Panel -> Network and Internet ->Network Sharing Center
1.) Click on your current Ethernet link.
2.) An Ethernet status box will come up. Click on the properties button.
3.) On the list, select Internet Protocol Version 4 (TCP/IPv4) located near the bottom.
4.) Click on properties.
5.) Change the bottom selection from “Obtain DNS server address automatically” to “Use the following DNS server addresses:” and enter
as your primary address
as the alternate DNS address.
Your computer/laptop is now secure. The procedure for Windows 10 is similar, but the actions are different.
1.) Right click on the start menu and select Network Connections. Next, right click on the connection you are using (it must be active with no red cross over it). Select Properties from this new list.
2.) Look for ‘Internet Protocol Version 4 (TCP/IPv4)’ and select it. Click on the Properties button.
3.) Change Obtain DNS server address automatically to “Use the following DNS server address and enter 22.214.171.124 as primary and 126.96.36.199 as the alternate. Click Okay to finish.
Flushing Your DNS Cache
You may need to flush your DNS cache for the settings to hold.
First, go to a command prompt window. In the programs run input box (click on the start menu to get to it, or use the “Ask me anything” box for Windows 10), type: ‘cmd’ followed by enter. Next, type ‘ipconfig /flushdns’ and hit enter. You may also want to reboot your computer too. Do not include the single quotes when typing things.
This is for more advanced users, but you can also configure your wireless router to make any device that connects to your router filtered by following these instructions on the OpenDNS site.
Dealing with YouTube
YouTube is a wonderful resource with just about any video ever made on it. Blocking it can be limiting for some people. With OpenDNS set, it will automatically filter YouTube videos so they are in “Safety Mode.” If you want to restrict YouTube videos without relying on OpenDNS, we have an article that explains how to turn on YouTube Safety Mode. You will need to decide for yourself if the Safety Mode settings on YouTube are good enough, but it is the best available. On KidzSearch.com we do not allow YouTube videos and have many child-friendly alternative video sites as good alternatives that are all reviewed safe videos.
Even with OpenDNS installed, if an image search is done on Google.com, it will show adult pictures. OpenDNS will prevent them from being opened, but having them show up in search results is an obvious problem. We suggest also setting Google SafeSearch to block them. See our guide to Locking Google SafeSearch
Unfortunately, there are a host of other image search engines that allow adult images to be viewed on them. We suggest using KidzSearch Image Search, since it only searches and displays safe image sources, such as selected educational and government websites.
Safe Web Search Engines
Using DNS filtering will prevent adult sites from appearing, but you will still get adult content in the search results if you are using a regular search engine, like Google, Yahoo, Bing, etc. However, they will be blocked if a child tries to open one of the adult links. A major problem is that you can still get explicit titles and even images appearing. A better approach is to use DNS filtering coupled with a SafeSearch website, such as KidzSearch.com. This method will block adult websites that are typed in a browser as well as blocking them from even showing up in the search results. You can also configure Google.com to only return SafeSearch websites, but that can get reset if cookies are cleared or if a different is used by your child. On a mobile device we suggested using the KidzSearch App
