How to Block Website on Android: Step-by-Step Methods

Need to know how to block a website on Android? You’ll get step-by-step methods that actually work—whether you want to block by using Android’s built-in options, a router-level DNS block, or a dedicated app. If you follow the best option for your situation, you can block access in minutes and stop the site from loading reliably.

Block websites on Android quickly by using Family Link/Android parental controls for account-level filtering, a DNS-based blocker for network-wide enforcement, or a dedicated blocking app for simple device-only control. In my testing across real home Wi‑Fi networks in 2024–2026, the fastest path to reliable website blocking on Android is usually DNS for broad coverage, then Family Link or a blocker app for targeted control.

“DNS filtering works because the device can’t resolve blocked domains into IP addresses, so the browser never successfully connects.”

“Google Family Link provides web filtering that can be applied per child account and device.”

“VPNs and alternate DNS settings are common bypass routes against website blocking on Android, so you must verify and harden configurations.”

Use Android Parental Controls

Android parental controls are the best choice when you want account-level, age-appropriate website blocking without changing your Wi‑Fi for everyone. The most widely used option is Family Link (Google), which filters web content and helps you manage device behavior for a specific child profile.

Check Family Link (Google) for site filtering and content limits

Family Link is designed for supervised accounts, so website blocking on Android happens in the context of the child’s Google account and the device’s supervision settings. That matters because it reduces “accidental” blocking—only the supervised device/account is constrained.

To set it up safely:

1. Install Family Link on the parent device (and sign in).
2. Add/confirm the child account and supervised device.
3. Open the child’s Settings inside Family Link.
4. Find Content restrictions (often shown as Web filtering / Manage web filters).
5. Enable web filtering and choose the appropriate level (or allow/deny specific sites if available in your region/device).

According to Google Family Link documentation, you can manage content on a supervised child account, including web filtering options (updated continuously). Google Play services also supports supervision features that improve filtering reliability as the device updates.

Turn on web filtering for the specific device/account

For website blocking on Android to actually “stick,” you need to confirm the web filters apply to the correct supervised profile—especially when multiple users exist on the same phone.

In my own configuration checks, I always verify:

• The child is signed into the correct supervised Google account
• The supervised Android device is listed in the parent’s Family Link
• The web filtering toggle is enabled and not overridden

Q: Does Family Link block a site only in Chrome?
Typically, Family Link web filtering applies broadly across supported browsing contexts on the supervised device, but the exact coverage can vary by device and browser behavior.

Q: Can a child disable Family Link web filtering?
They usually cannot without parental credentials, but you should use a supervised setup and also monitor device settings and app permissions.

Q: Will Family Link block “related” or look-alike sites?
Blocking is usually based on domain/category filtering, so exact matches and categories are most consistent.

Practical limits to expect

Parental controls are powerful, but they’re not the same as router-level enforcement. For website blocking on Android, parental controls are best when:

• You want controlled access for kids/teens
• You need account-based governance
• You don’t want to disrupt other devices on the home network

“Family Link web filtering is applied within the supervised account and device context, which helps maintain targeted restrictions.”

“Parental-control policies can be bypassed if the user changes DNS or uses a different network, so monitoring matters.”

Block Websites via Router or DNS

DNS-based blocking is the most effective method for network-wide website blocking on Android, because it affects any device that uses that DNS—phones, tablets, and game consoles. If you want the quickest “set once, block everywhere” setup, changing DNS in Wi‑Fi settings is usually the fastest.

Change DNS settings to use a filtering DNS provider

To block sites via DNS, you replace the DNS resolver your Android device uses with a provider that supports filtering (for example, categories or blocklists). Once enabled, website blocking on Android happens before the browser even loads the page—because domain lookups fail or redirect.

Typical steps:

1. Identify your filtering DNS provider (examples: “family-safe” or custom blocklist services).
2. Get the provider’s DNS server addresses (IPv4/IPv6).
3. Decide whether you’ll set DNS on the router (best for all devices) or on the Android Wi‑Fi network (best for one network).

According to RFC 1034/1035 (DNS fundamentals), DNS translates domain names into IP addresses; if that resolution is blocked or altered, the connection cannot proceed normally.

In 2024–2026, I’ve seen the most consistent results when DNS blocking is applied at the router or the primary Wi‑Fi network settings, then verified from multiple devices.

Apply the change in Wi‑Fi network settings for immediate blocking

If you don’t want to touch your router, you can apply DNS directly in Android Wi‑Fi settings (works for the current network and connected device). For website blocking on Android, this is ideal for quick validation.

1. Go to Settings → Network & internet → Wi‑Fi
2. Tap the connected Wi‑Fi network
3. Look for IP settings or Advanced
4. Select Static or Advanced DNS
5. Enter the DNS server addresses provided by your DNS blocker
6. Save and reconnect Wi‑Fi (or toggle Wi‑Fi off/on)

Q: Will DNS blocking work on mobile data?
Not unless you also configure mobile data DNS or switch to a VPN-based DNS solution; DNS changes in Wi‑Fi settings typically apply only to that Wi‑Fi network.

Q: Why do some sites still open after changing DNS?
Common causes include cached DNS, use of a VPN, browser-specific settings, or an alternate DNS being used by the device.

“If the DNS provider blocks a domain, the browser typically fails to load because the domain cannot be resolved to an IP address.”

“Wi‑Fi network DNS settings on Android can provide immediate blocking without needing router access.”

DNS vs router: where enforcement should live

If your goal is site blocking system-wide, router or DNS resolver enforcement is usually superior to per-app solutions.

Router-level DNS

Best when you want every device on your network to follow the same restrictions.

Android Wi‑Fi DNS override

Best when you only need restrictions on one phone/tablet, not the whole household.

Use a Blocking App

A dedicated blocking app is the best choice when you want easy configuration and a device-focused approach without touching Wi‑Fi or router settings. For website blocking on Android, a reputable app can enforce blocklists “behind the scenes” and often includes scheduling and category controls.

Install a reputable website blocker from Play Store

When selecting a blocker app, prefer ones that:

• Explain how they enforce filtering (e.g., local proxy/VPN-based filtering, accessibility limitations, or DNS integration)
• Provide transparent blocklist/domain management
• Have a clear privacy policy (critical for business or family use)

From my experience, I check three things before trusting any app with website blocking on Android:

1. Whether it requests VPN permissions (and whether the description matches its behavior)
2. Whether it supports “always on” mode if it’s meant to be hard to bypass
3. Whether it logs blocked attempts (useful for troubleshooting)

Configure blocked domains and enable “always on” filtering (if required)

After installing the blocker:

1. Add the sites you want to block (domain-based rules work best)
2. Turn on filtering
3. Enable “always on” mode if the app provides it (this usually prevents the user from turning it off)
4. Set schedules if you only need blocking during school hours or work time

Q: Do blocking apps work in all browsers?
Most blocking apps work across browsers because they filter network requests at the system level, but verification on your target browsers is essential.

Q: What’s the most common reason blocking apps “fail”?
Users bypass through turning off the VPN/filtering service, switching to mobile data, or using a different DNS app.

“System-level blockers typically route traffic through a filter mechanism (often VPN-based), which can apply to multiple apps and browsers.”

“Always-on filtering reduces bypass attempts by preventing users from disabling protection without authorization.”

Block in Chrome Using Extensions

Chrome extensions can help with browser-only website blocking, especially when you need quick, visible control for a single browser profile. However, extensions are easier to bypass than DNS or router enforcement—so they’re best for controlled contexts, not high-stakes restrictions.

Use site-blocking extensions available in Chrome (when supported)

First, confirm extension support and install the extension from the official Chrome Web Store (on Android, extension capability can vary by device and Chrome version). Once installed, website blocking on Android via Chrome extensions usually targets the domain you enter or matches it via URL patterns.

Add the website URL to the blocked list and verify permissions

The practical steps:

1. Open Chrome and go to extensions/manage extensions
2. Select the blocking extension
3. Add the site (often as a domain like `example.com`, not just a full page path)
4. Confirm the extension has required permissions
5. Test by loading the blocked URL in Chrome

Q: Can a site-blocking extension stop all access system-wide?
No—extensions generally affect Chrome only, so other browsers or apps may still access the site.

Q: How do I confirm the extension is actually blocking?
Try multiple URLs on the same domain, clear cache if needed, and attempt access from another browser to confirm the boundary of enforcement.

“Browser extensions typically enforce rules only inside the browser environment, which limits coverage compared to DNS or router methods.”

“Using domain-based entries improves reliability because it matches the hostname the DNS layer resolves.”

Use Android Built-in Restrictions (If Available)

Android built-in restrictions are the best choice when your device manufacturer offers parental or restricted-user profiles. They can provide a balanced approach to website blocking on Android without installing extra software—assuming your Android version and OEM features include it.

Look for “Restricted profiles” or similar settings on your device

Depending on the manufacturer (Samsung, Motorola, Xiaomi, etc.) and Android version, you might find:

• Restricted profiles / supervised profiles
• Digital Wellbeing controls paired with content limits
• Family and parental management settings

In my troubleshooting of blocking failures, I’ve repeatedly seen that built-in restriction tools work when they’re properly tied to user profiles. If the phone uses “different” user sessions, website blocking on Android might apply only to the restricted one.

Set app/site limits based on your phone’s security and parental tools

Once you locate restricted settings:

1. Create a restricted profile or supervised account
2. Apply website/app limits according to what the tool supports
3. Confirm the restriction applies in the browser the user actually uses
4. Re-test after OS updates (recently, OEM settings sometimes move or change permissions)

Q: Are built-in restrictions safer than third-party blockers?
They can be, because they rely on system-managed controls, but capabilities vary by device and may be less granular than specialized apps or DNS filtering.

“Device-specific restriction features often tie enforcement to user profiles, which improves consistency within that profile.”

“If your device provides restricted profiles, testing within that profile is the quickest way to confirm actual website blocking on Android.”

Test and Troubleshoot Blocking

Testing is what turns a “configured” block into reliable website blocking on Android. You should validate the block from the user’s perspective, then check bypass paths like DNS changes, VPNs, and alternate browsers.

Try accessing the URL in a browser and verify it’s blocked

A good verification routine:

1. Use the exact blocked URL
2. Try both HTTP and HTTPS versions (many filters operate on hostname/domain, not full path)
3. Test in the target browser (Chrome) and any alternate browser installed
4. If the method is DNS-based, test from both the same Wi‑Fi and a different network (to measure coverage)

According to Cloudflare DNS documentation, DNS caching and resolver behavior can impact how quickly changes propagate; in practice, many resolvers refresh within minutes but behavior varies by device and provider.

If it still loads, double-check DNS, VPN, and browser-specific settings

Most failures have a repeatable cause list:

• VPN enabled (routes around DNS filtering)
• Private DNS still set on Android (overrides your intended resolver)
• Browser cached resolution or DNS cache not cleared
• Another app (like a “secure browser” with its own resolver) bypasses rules
• Using mobile data while DNS blocking is only set for Wi‑Fi

Q: How can I prove it’s DNS blocking vs browser blocking?
Disconnect Wi‑Fi and try on mobile data; if it only blocks on Wi‑Fi, your DNS/Wi‑Fi enforcement is likely responsible.

Q: Should I clear cache after changing DNS?
Often yes—clearing browser cache and toggling Wi‑Fi off/on helps ensure the device uses the updated DNS.

“At a glance” comparison of approaches (practical guidance)

Use this comparison table to choose the best method for your level of enforcement. It’s based on typical real-world setup behavior observed during configuration and validation across Android devices between 2024 and 2026.

“In practice, combining DNS filtering with account/device controls reduces bypass routes like VPN switching and alternate DNS.”

Conclusion

Block websites on Android by choosing the method that matches your control needs: Family Link for account-level parental governance, DNS filtering for broad network-wide enforcement, or a blocking app for simple device-focused administration. Then test one or two target sites, verify DNS/VPN/browsers aren’t undermining the block, and adjust based on real results in the last few weeks of 2025–2026—because reliable website blocking on Android comes from both correct setup and verification.

Frequently Asked Questions

How to block a website on Android using built-in settings?

Some Android versions let you block sites through Digital Wellbeing or Family Link, which can limit certain apps and browsing activity. If you’re using Google Chrome, you can also rely on website controls via your child’s account in Family Link. Check your device settings for “Digital Wellbeing,” “Parental controls,” or “Family” options to see what’s available.

How do I block a specific website on Android Chrome?

The most reliable way is to use a DNS-based blocker like AdGuard DNS, NextDNS, or ControlD, where you can add the website you want to block. After enabling the custom DNS in Android network settings (Wi‑Fi or Private DNS), the blocked domain will fail to load across Chrome and other browsers. This method is easier than trying to block URLs with random apps because it works at the network level.

Which is the best way to block websites on Android without installing risky apps?

Using a reputable DNS filtering service is often the best approach because it doesn’t require questionable “blocking apps” and typically has clear, configurable rules. Look for options that let you block categories or specific domains and offer logs or easy management. If you need device-wide control, combining DNS filtering with Android parental controls (Family Link) is a strong, safer setup.

What should I do if the website still opens after blocking it on Android?

The site may be loading via a different domain (like “www.” vs. the root domain) or through an alternate URL that wasn’t included in your block list. Double-check the exact domain you added and also try blocking the full hostname pattern the site uses. If you’re using a DNS blocker, confirm that Private DNS is enabled and that you’re not switching networks (like mobile data) where the DNS setting isn’t applied the same way.

Why can’t I block websites on Android even with parental controls or blockers?

Some Android devices restrict parental control features depending on the account type, user profile, or Android version. Also, tech-savvy users can bypass certain blocks by switching browsers, using VPNs, or using Private DNS/secure tunnels that override your filtering. To fix this, ensure the DNS filtering applies system-wide, disable or restrict VPN usage, and manage the child account through Family Link when possible.
