If you are a parent, you can block all websites except a few on the computer and phone that your kid uses to completely control the content your kid can access online. If you are an employer, you can allow only certain websites on work computers to effectively reduce digital distractions and help keep your employees productive.
This article will show you how to block access to all websites except one or two (or more) websites.

You can easily edit the Allowlist at any time.

However, Family Safety for Windows 10 removes the option to allow only selected websites. Luckily, there is still a built-in way to restrict all websites except a few.
1. On your computer, open Internet Explorer.
2. Click the Tools icon in the top right corner and choose Internet options.
3. In the Internet Options window that appears, go to the Connections tab. Click LAN settings.
4. Check the box next to Use a proxy server for your LAN.
5. Enter “127.0.0.1” in the Address box. Enter “80” in the Port box. Click Advanced.
6. In the Proxy Settings window, go to the Exceptions section.
7. Enter the websites that you want to whitelist. For example, to block all websites except Gmail, enter “mail.google.com”. Make sure that you use semicolons to separate websites.
8. Click the OK buttons.
Once the blocking is applied, all websites excluding the ones that have been whitelisted are blocked on Google Chrome, Internet Explorer, Microsoft Edge, Firefox or other web browsers on your Windows PC. This way, all potentially inappropriate or distracting websites are completely inaccessible.
Applies to: Android 10 or above
If you want your kid to be able to access only selected websites on his or her Android phone and stay safe online, you can try Google Family Link, a parental controls service by Google. It will require some setup. Let’s get started.
1. Install the Google Family Link app. Open it.
2. When asked if you want to create a Google account for your child, click Yes.
3. Create an account.
4. On your child’s Android device, sign in with his or her account.
5. Enter the password of your own account to verify that you are a parent.
6. Install Google Family Link on child’s Android device.
7. On your Android device, go to Parent settings in Google Family Link.
8. Tap Filters on Google Chrome. Now you have three options. Choose Only allow certain sites.
9. Tap Manage Sites and add specific websites to allow. For example, to block all websites except Google, add the domain URL “google.com”.
Now all websites excluding the allowed ones are blocked on Chrome on your kid’s Android device. If your kid wants to use a website not in the allow list, he or she can send you a request. Once you approve the request, the website will be unblocked.
Applies to: iOS 12 or later
If your or your child’s iPhone is running iOS 12 or later, then Screen Time is available for you to control web content in a few ways, such as allowing only few websites.
1. On your or your child’s iPhone with Screen Time, go to Settings > Screen Time.
2. Tap Turn on Screen Time to enable it.
3. Tap Use Screen Time Passcode. Set a passcode. This is optional and recommended.
4. Tap Content & Privacy Restrictions.
5. Enable Content & Privacy Restrictions, which will require you to enter the passcode.
6. Tap Content Restrictions > Web Content.
7. By default, all websites are allowed and accessible. You need to enable Allowed Websites Only.
8. Tap Add Website to add specific websites to allow one by one.
If your iPhone is running iOS 11 or earlier, don’t worry. There is a similar feature available. The feature is called Restrictions, and you can find it in Settings > General.
The hosts file is a system file named “hosts”. You can find it on a Windows or macOS computer, an iPhone or an Android phone, etc. You may already know that it’s possible to block certain websites by editing the hosts file.
It’s also possible to use the hosts file to restrict Internet access to only certain sites. But it’s not recommended to do so unless you are confident with this method.
1. In the hosts file, list the IP address of each allowed website, followed by the website name.
2. To block all sites excluding the listed ones, you need to block all TLDs (top-level domains).
For details, please see this post.
Again, if you are not confident or familiar with this method, don’t try it.
If your Wi-Fi router comes with parental controls containing a whitelist feature, then the answer can be yes.
It takes certain setup to apply the blocking. And the setup can be different, depending on the router brand and model.
If you don’t want to mess up with your router’s settings, please ignore this.
1. Access your router’s settings by logging in.
2. Find the parental controls, web filtering or similar settings. On some routers (such as ASUS ZenWiFi AX), the settings can be hidden in the firewall settings.
3. There should be two filtering types: the blacklist and the whitelist. Enable the latter.
4. Add specific websites or URLs to the whitelist one by one.
5. Save your settings.
Now the blocking should be implemented on your web browser, be it Chrome, Internet Explorer, Firefox, Edge or Safari, etc.
We block certain websites to get rid of addictive, violent, explicit, drug or other unwanted websites. But sometimes it’s not enough. There are numerous potentially distracting or bad websites out there. They may be just a click away from your children, your employees or yourself. It’s a good idea to block all websites except a few needed ones. This article shows how to easily allow only few websites on computers and smartphones. I hope it helps.
