How to Block Internet Sites on Android: Step-by-Step

Want to block internet sites on Android? This step-by-step guide shows the fastest, most reliable way to restrict specific websites—whether you’re using built-in Android controls, DNS filtering, or a trusted parental app. Follow the steps, and you’ll know exactly how to block a site, verify it’s blocked, and keep the settings from being easily bypassed.

Blocking internet sites on Android is easiest when you match the method to your goal: use Family Link for child/account-level control, a site-blocking app for direct URL lists, or Private DNS for system-wide filtering across apps. In this guide, you’ll learn practical, step-by-step ways to block websites on Android phone or tablet and the quick checks I use to verify the blocks actually work in real browsing—not just on paper.

Check Your Best Option (Family Link vs Browser vs DNS)

The best option depends on whether you’re blocking for a child account, a single browser, or your whole device. In my experience setting these up across different Android versions (and testing with multiple browsers), DNS-based filtering is the most “global,” Family Link is the most managed for families, and browser-level controls are best for quick, limited restrictions.

Private DNS is supported in Android 9+ and lets you route DNS lookups through a provider of your choice for system-wide filtering.

Family Link provides account-based supervision, including “blocked sites” that apply when the child uses the controlled Google account.

DNS filtering works across most apps because many apps rely on domain names resolved via DNS, not just the browser.

Here’s a direct decision view:

• Family Link is ideal if you’re managing a child Google account and want rules tied to identity.
• Website blocking apps are ideal when you want explicit URL/domain lists and simple on/off control on the device.
• Private DNS is ideal when you want system-wide domain/category filtering (most apps), but it can be bypassed if the device is configured to use another DNS route (e.g., a VPN).
• Browser-level blocking is best when you only need to restrict one browser profile (e.g., Chrome but not other apps).

Q: What’s the most “set it and forget it” method on Android?
Private DNS is typically the most comprehensive for system-wide filtering because it impacts domain resolution across apps.

Q: Will Family Link block sites in every app?
Family Link’s blocked sites primarily target browsing behavior under the supervised account; it’s most consistent in supported Google-managed contexts rather than every single app.

To help you choose quickly, use this comparison:

Now, if you’re leaning toward DNS filtering, it helps to understand common providers and what they typically offer. (This is not an endorsement—just a practical snapshot for setup planning.)

Block Sites Using Google Family Link

The fastest way to block sites for a child on Android is usually Google Family Link, because it links restrictions to the child’s Google account instead of just a specific app. When Family Link is set up correctly, blocked sites and content filters become enforceable in the supervised profile, and you can also manage screen time and app approvals.

Family Link is an account-based supervision tool that lets parents manage a child’s Google account settings from a parent device.

In Family Link, “Blocked sites” settings are meant to prevent access to specific domains when the child attempts to browse.

Family Link restrictions are typically enforced in supported browsing contexts for the supervised Google account.

Start by adding the child’s Google account to Family Link:

1. Open Family Link on your Android or iPhone.
2. Sign in with your Google account, then add the child and follow the setup prompts.
3. On the child device, confirm permissions and supervision activation.

Then configure website restrictions:

• Go to Family Link settings for your child.
• Look for Content restrictions / Manage content.
• Choose Blocked sites (or similar naming) and add the domains you want to block.

A practical tip from my testing: add the root domain (e.g., `example.com`) rather than trying to block every possible subpage URL. DNS-style blocking can be inconsistent if only a deep path is listed, but domain-level blocks tend to be more reliable.

Q: Does Family Link require the child to use a specific browser?
Family Link is account-based, so restrictions are designed to apply broadly in the supervised environment; however, enforcement can vary by app and browser support.

Verify the block in a way that catches real-world failures:

1. Open the child’s browser (often Chrome).
2. Navigate to a restricted domain you just added.
3. Confirm the browser shows a block message or an inability to load the page.
4. If it loads, revisit whether the child account is properly supervised and whether the site was added in the exact format Family Link expects.

Block Sites Using a Website Blocking App

If you need fast, direct control over a list of domains, a website blocking app from Google Play is usually the quickest path. These apps typically work by intercepting web requests or managing DNS rules at the device level (depending on the app), and most let you maintain a blocklist that updates immediately.

Many Android site-blocking apps require explicit permissions to filter web traffic at the device or browser level.

Blocklists in site-blocking apps are typically enforced by matching domain names, not just full URLs.

After enabling a blocker, testing with an already-known restricted URL helps confirm enforcement.

Step-by-step approach:

1. Install a reputable site blocker from Google Play.
2. Open the app and grant all required permissions (the app will usually explain why each permission matters).
3. Add websites or categories you want to block.
4. Turn the blocker On.

What I look for during setup:

• Clear toggles for “enabled” status
• Transparent reporting (recent blocked attempts, rule matches)
• Options for domain vs URL matching
• Compatibility with common browsers (Chrome, Firefox, Samsung Internet)

Comparison snapshot (what can differ across apps):

Feature	What you should check	Why it matters
Domain matching	Does it block `domain.com` and subdomains?	Most people forget subdomains like `www.` or `m.`
Browser compatibility	Does it support Chrome specifically?	Some apps focus on specific engines or profiles
Bypass risk	Can users disable the service easily?	Enforcement weakens if the user can stop it
Logging	Does it show blocked events?	Logs let you verify blocks without guessing

Q: Can a site blocker stop all traffic if I use multiple browsers?
It depends on the app’s enforcement method; some filter system-wide, while others only target specific browsers.

Finally, test properly:

• Use a previously blocked URL and check it loads.
• Then try a second browser to confirm whether the blocker is browser-only or truly system-level.
• If the second browser bypasses the rule, you may need system-wide DNS filtering instead (or select an app with broader enforcement).

Block Sites by Using Private DNS (DNS Filtering)

For the broadest coverage, enable Private DNS and select a DNS filtering provider. Because DNS (Domain Name System) is how devices translate website names like `news.example.com` into IP addresses, DNS filtering can block domains across many apps—not only a browser.

Private DNS routes DNS queries through the configured provider, affecting name resolution across apps.

DNS-over-TLS commonly uses TCP port 853, while DNS-over-HTTPS commonly uses TCP port 443.

Android’s Private DNS setting is designed to apply system-wide for DNS resolution when configured correctly.

Step-by-step:

1. On your Android device, open Settings.
2. Tap Network & Internet (wording varies by manufacturer).
3. Tap Private DNS.
4. Choose one of:

• Off (to test baseline), then
• Private DNS provider hostname (and enter the provider’s hostname), or
• Select a built-in provider if your Android version lists one.

1. Save and wait for the network to re-connect.

According to Android Developers (Private DNS documentation), Private DNS is intended to change how your device resolves hostnames (domain-to-IP lookups), which is exactly what blocking relies on.

Also keep in mind one operational reality: DNS filtering is only as strong as your device’s path to DNS. If a VPN or an alternative DNS mechanism is enabled, traffic may bypass Private DNS.

To anchor your troubleshooting, use these concrete checks:

• Try loading a blocked domain in Chrome and another browser (e.g., Firefox or Samsung Internet).
• If one browser still loads, check browser-specific settings like DNS-over-HTTPS toggles (some browsers can perform their own secure DNS).

Q: Will Private DNS block apps that don’t use a browser?
Often yes—if the app reaches websites by resolving domains through DNS, the DNS filter can block that resolution.

In my own testing in 2025 on multiple Android builds, the most reliable verification is to test from at least two different apps that normally open URLs (a browser and a content app that has embedded web views). That catches cases where one app uses a different networking stack than expected.

Use Browser-Level Blocking (Quick Setup)

If you only need to restrict one browser, browser-level blocking is the fastest setup with the lowest risk of breaking other apps. This approach is helpful when you’re trialing restrictions temporarily or when full system-wide filtering would be too aggressive.

Browser extensions and built-in browser content controls can restrict access to specific websites within that browser’s profile.

After browser updates, extension permissions or blocklist rules may reset and should be re-validated.

Start with Chrome (and then replicate if needed):

1. Open the browser settings (Chrome: Settings → Privacy & security).
2. Look for:

• Site restrictions / content controls
• Safe browsing settings
• Managed profiles (if available)

1. If the browser supports it, use a parental control extension or a built-in blocklist feature.

If you’re using another browser:

• Check whether the browser supports managed profiles (common on corporate or managed devices).
• If it supports extensions, choose one that specifically blocks domains (not just “adult content” heuristics).

Q: What’s the biggest limitation of browser-level blocking?
It typically won’t affect other browsers or in-app webviews, so users can often bypass restrictions by switching apps.

Re-check settings after changes:

• Browser updates
• Profile switches
• Clearing site data in the browser
• Installing/removing extensions

From my experience, browser-level controls are excellent for “temporary governance,” but for family or workplace enforcement, Private DNS or Family Link tends to be more consistent.

Troubleshooting: If Sites Still Open

When blocked sites still load, it usually means the filter isn’t being applied to the traffic you’re testing. In practice, the most common causes are cached results, bypass routing (VPN/alternate DNS), or the site-block rule format not matching the domain the browser actually requests.

Clearing browser cache and cookies can be necessary to ensure new blocking rules take effect.

A VPN or custom DNS configuration can bypass Android Private DNS filtering by rerouting network traffic.

Blockers that rely on domain matching may fail when users enter a full URL instead of the root domain.

Try these fixes in order:

1. Clear browser cache/cookies

• In Chrome: Settings → Privacy → Clear browsing data
• Then retry the blocked URL.

1. Test in a private/incognito window

• Incognito reduces cookie-based exceptions and cached redirects.

1. Disable VPN and DNS alternatives

• Turn off VPN first, then re-test.
• If you use an app that sets its own DNS, disable it temporarily.

1. Re-check permissions and on/off state

• For site-blocking apps, confirm the service is enabled and still running.
• For Family Link, confirm the device remains supervised for the correct Google account.

1. Validate the domain format

• Add `example.com` rather than a single long URL.
• Include both the bare domain and `www.` if your target provider matches strictly.

Q: How do I confirm whether the block is working at the DNS level?
Use two browsers (or a browser + another networked app) after enabling Private DNS; if both still resolve and load, DNS filtering may be bypassed.

If you want a fast “root cause” test, I recommend this sequence: disable VPN → confirm Private DNS is set → restart the browser → test in incognito. In my own checks, this process usually reveals whether the issue is caching, bypass routing, or a misconfigured filter.

When you block internet sites on Android, the fastest options are Family Link for account-based control or a site-blocking app for explicit URL/domain lists; for broader protection, use Private DNS filtering. Pick the method that matches your goal, add the domains you want to restrict, and then verify the blocks using at least two test apps or browsers. If you’re setting this up for a child or multiple devices, start with Family Link or Private DNS, and adjust permissions as needed to balance safety with usability.

Frequently Asked Questions

How do I block specific websites on Android without an app?

You can block websites on Android using built-in options like Private DNS or by using DNS-based filtering. Go to Settings > Network & internet > Private DNS and set a filtering provider or custom DNS hostname that blocks unwanted domains. If your phone doesn’t support filtering DNS for specific sites, consider using Android’s built-in browser restrictions (if available) or enabling a family/parental control service.

What is the best way to block internet sites on Android for kids?

The best approach is to use a dedicated parental control app or family link that supports website filtering per user profile. These tools typically let you block categories (like adult content) and specific domains while also showing usage reports. Make sure the app is installed under the child’s device profile and that the settings are protected with a PIN to prevent easy changes.

Which Android browser supports website blocking or restrictions?

Many browsers don’t offer true per-site blocking built in, so the most reliable method is DNS-based filtering or parental control apps. If you use Chrome, you can still benefit from Private DNS filtering or system-wide parental controls that affect all browsers. For stricter control, choose a solution that blocks at the network/DNS level so the restriction works in Chrome, Firefox, and in-app browsers.

How can I block a website on Android using Private DNS?

Open Settings > Network & internet > Private DNS and select “Private DNS provider hostname.” Enter a DNS hostname from a filtering provider (or a custom DNS you control) that blocks categories or specific domains. After saving, test by reopening the site in Chrome or another browser; the page should fail to load or show a block message.

Why won’t blocked websites load on my Android even after I set restrictions?

This usually happens because the browser is using a different network path (like mobile data vs Wi‑Fi) or the DNS settings weren’t applied system-wide. Try switching between Wi‑Fi and mobile data to confirm the block works on both, and clear the browser cache/cookies if you previously visited the site. Also check for VPN or Private DNS overrides—VPNs can bypass DNS filtering and make site blocks ineffective.
