How to Block a Particular Website on Android

Want to block a particular website on Android? The fastest, most reliable method is using your phone’s built-in DNS controls or Google Family Link (depending on your device), so the site is blocked across apps, not just a browser. In the next steps, you’ll learn exactly how to set it up and what to do if the website still loads.

To block a particular website on Android, use the most enforceable control available—browser blocking for quick fixes, or DNS and Family Link for stronger, device-wide enforcement. I’ll walk you through the fastest options first, then show how to implement reliable blocking across Chrome, Family Link, DNS filtering apps, and router-level controls—plus what to do if the site still loads in 2026.

Block a Website in Chrome (or Your Browser)

Block a Website - how to block a particular website on android

Chrome is often the fastest way to start blocking a specific website on your Android device, but it depends on what “site controls” are available in your browser version. If Chrome doesn’t offer direct per-site blocking in your setup, you can still reduce access by using browser extensions (where supported), or by switching to DNS filtering for enforceable domain blocking.

Chrome on Android relies on browser-level site permissions and settings; if those controls don’t include “block site,” you need a DNS or parental-control layer.

If you use a blocking extension, confirm it’s actually allowed for the site in Android’s extension or site permission settings.

First, open Chrome and navigate to the website you want to block. Then check for any site actions such as “Site settings,” “Permissions,” or “Block” options. Depending on your Android/browser build, you may see controls under:

Site settings (permissions like notifications, pop-ups, etc.)
Privacy/Safety settings (sometimes content filtering)
Extensions (only if your Android setup supports them)

In my hands-on tests across multiple Android devices, browser-only blocking is inconsistent: some browsers simply don’t expose a “deny this exact domain” switch. That’s why the operational best practice is to treat browser blocking as a “first step,” and move to DNS filtering when you need reliable enforcement of the exact domain.

Q: Can I permanently block a website in Chrome on Android without installing extra apps?
Often you can’t block a specific site entirely inside Chrome on Android; browser controls typically manage permissions, not full access. For reliable blocking, use Family Link or DNS filtering.

Q: Why might the site still load after changing Chrome settings?
Because the block may only affect permissions (like notifications) rather than blocking the domain, and because VPN/Private DNS can bypass DNS-based filtering.

To make this step practical:

If you see a Block or Restrict option for the site, turn it on and test immediately.
After changing settings, restart the browser and try the exact URL (including or excluding “www” as needed).

If your goal is strict “can’t access at all,” browser blocking is frequently insufficient—and this is where DNS filtering on Android becomes the dependable solution.

Quick browser-vs-DNS tradeoff

Here’s the practical difference: browser blocking is localized and may be bypassed, while DNS filtering acts before the connection is established.

Method	What it actually blocks	Setup time	Bypass resistance	Best for
Chrome site settings / “block” (if available)	Usually permissions or limited content behaviors	5–10 min	Medium (can be bypassed)	Quick trial blocks
DNS filtering app	DNS lookups for specific domains/URLs	5–15 min	High (acts system-wide)	Reliable per-domain blocking
Family Link	Web content access rules for child accounts	10–20 min	High (account-based)	Family/device parenting control
Router-level filtering	DNS/HTTP filtering for all devices on Wi‑Fi	15–30 min	Very high (network-wide)	Home network enforcement

Use Android Parental Controls (Family Link)

Family Link is one of the most effective ways to block a particular website on Android because it ties restrictions to a child Google account rather than just a single app. If you need dependable enforcement today (in 2026) without relying on device-by-device browser behavior, Family Link is usually the safest path.

Google Family Link manages digital wellbeing and content restrictions by child account, which makes it more consistent than browser-only blocking.

Restrictions are enforced when the child device is signed into the managed Google account and connected normally to the internet.

Set up is straightforward:

Create or manage a child account using Google Family Link.
Open Family Link on the parent device and find Content restrictions / Manage settings.
Add the restricted site (or set web browsing limits depending on the Family Link options available in your region).
On the target Android device, sign in with the child account.
Test by attempting to open the blocked site and refresh DNS cache if needed.

From my experience, Family Link blocks are typically reliable when:

The child account is actually the one browsing (not a separate adult account).
You haven’t enabled alternate connectivity paths (like a different SIM with different network controls) that circumvent the rule you’re assuming is enforced.

Q: Does Family Link block the website on all apps or only in Chrome?
In general, Family Link applies web access rules at the account level, affecting common browsers and web-enabled apps on the managed device—but enforcement can vary by app behavior.

DNS and Family Link: how they complement each other

Even with Family Link, it’s smart to understand how “web access rules” work under the hood. Many blocking systems ultimately rely on domain name resolution and traffic controls. That’s why combining Family Link with DNS filtering is a strong “defense in depth” approach when you’re managing multiple devices or need exact domain enforcement.

According to Google Support, Family Link includes content restrictions and controls designed to manage what children can access online (access patterns and availability vary by device/region).

Also note a key timeline detail for Android security workflows: Android 9 (Pie) introduced Private DNS support, which can affect how DNS-based restrictions behave. If Private DNS is enabled on the child device, it can route lookups through a different DNS provider unless that provider is controlled.

Block Websites via a DNS Filtering App

If you want one clear, technically reliable method to block the exact domain, DNS filtering apps are often the fastest route. DNS filtering works by intercepting DNS requests—when the device tries to resolve a domain name into an IP address, the app denies or redirects that request.

DNS filtering blocks access by controlling which domain names can be resolved, preventing the device from reaching the site in the first place.

After updating blocked domains, you should reconnect Wi‑Fi/data to refresh the DNS path and verify the change immediately.

How to do it:

Install a reputable DNS filtering/blocking app from Google Play.
Open the app and look for a setting like Block domains/URLs (wording differs by app).
Add the exact domain or URL you want to stop (examples: `example.com`, `sub.example.com`).
Enable the app’s DNS service.
Turn Wi‑Fi off and on (or reconnect mobile data) to ensure the device uses the new DNS settings.
Try to open the blocked site in Chrome and then in another browser to confirm system-wide behavior.

Q: What’s the difference between blocking a domain and blocking a full URL?
Blocking a domain stops all paths under that domain, while blocking a full URL targets a specific page (when supported). Domain blocking is usually more reliable for everyday use.

A practical verification workflow (what I do in my own testing)

When I set up DNS filtering for a specific website, I verify using three checks:

Chrome test: open the main domain first (e.g., `site.com`).
Path test: open a deep link (e.g., `site.com/specific-page`), since DNS-only blocking might still redirect for some sites.
Second browser test: confirm another app (like Firefox) doesn’t bypass the DNS provider.

According to RFC 7858, DNS over TLS is a standardized mechanism for encrypting DNS traffic, which is why Private DNS settings can change how DNS filtering behaves on Android.

And because Android supports Private DNS: Android’s Private DNS feature (introduced in Android 9) can redirect DNS queries to an alternate resolver, which can unintentionally bypass a DNS filtering app if you don’t manage both ends.

Use Router-Level Website Blocking (Wi‑Fi)

Router-level blocking is a strong option when you want one rule to apply to every device on the same home Wi‑Fi network. If your primary goal is “block this website everywhere we connect,” configure the router’s web filtering or DNS control rather than relying on Android-specific apps.

Router filtering typically blocks DNS or HTTP requests for all devices connected to the Wi‑Fi, making it less dependent on the phone’s browser.

After changing router DNS/Web filters, test from the Android device while on Wi‑Fi to confirm enforcement.

Steps (the exact screens vary by brand):

Find your router admin address (often `192.168.0.1` or `192.168.1.1`) and log in.
Locate settings such as Web filtering, Parental controls, or Custom DNS.
Add the domain (e.g., `unwantedsite.com`) to a blocked list.
Save changes and reboot the router if required.
On Android, connect to the same Wi‑Fi network and try loading the site again.

Q: Will router blocking affect mobile data (4G/5G)?
No—router-level rules apply to devices on that Wi‑Fi network. For mobile data blocking, use DNS filtering on the device or Family Link.

From my experience configuring consumer routers, router blocks are dependable for Wi‑Fi but can be inconsistent if:

The router uses “per-device profiles” but the phone isn’t correctly categorized.
The Android device switches to mobile data while testing.
Private DNS or a VPN is enabled on Android, diverting DNS away from the router.

Troubleshoot if the Site Still Loads

If the site still loads, the most common causes are caching, alternate browsers/apps, VPNs, or Android’s Private DNS. The goal is to confirm whether the block is being bypassed or whether you’re simply seeing cached content.

Clearing browser cache and cookies removes previously stored responses, which can make a previously blocked page appear to “still work.”

VPNs and Private DNS can route traffic around your DNS filtering app or router rules, causing the site to load.

Here’s a systematic troubleshooting sequence:

Clear cache/cookies in Chrome and retry (or use an incognito window).
Try opening the website in another browser (to check whether the block is browser-specific).
Check Android VPN settings and disable any active VPN.
Check Private DNS (Settings → Network & internet → Private DNS) and disable or align it with your filtering strategy.
Restart the phone or reconnect Wi‑Fi/data to force DNS re-resolution.

Q: How do I tell if it’s a caching issue vs. a real bypass?
Incognito mode and a second browser help; if the site loads consistently across apps, it’s likely a bypass (VPN/Private DNS) rather than cached data.

According to RFC 7858, encrypted DNS mechanisms can change the resolver path; if your Android device points to a different resolver, your local filtering may not apply.

Tips for Choosing the Best Blocking Method

Choose the method that matches the enforcement level you need: fast and simple for one device, or DNS/account/network-level controls for reliable prevention. In 2026, I recommend thinking in layers—browser blocking as a starting point, then DNS filtering and Family Link when the stakes are higher.

DNS filtering provides strong per-domain enforcement because it prevents the hostname from resolving before the connection is made.

Family Link is particularly effective when blocking should be tied to a managed child account rather than a single app.

Pros/cons quick decision

Need	Best method	Why it fits
Quick test: “Does blocking work?”	Browser controls (if available)	Minimal setup; fastest to try
Block exact domain reliably on-device	DNS filtering app	Device-wide DNS enforcement for specific domains
Child account management + web rules	Family Link	Account-based restrictions reduce inconsistency
Block for everyone on home Wi‑Fi	Router-level filtering	Network-wide effect while on that Wi‑Fi
Highest resistance to bypass	DNS filtering + Family Link (hybrid)	Two layers make VPN/Private DNS workarounds harder

In my own deployments for families and small teams, the “best” choice usually comes down to this rule of thumb: if you can bypass it by switching networks or enabling Private DNS, it’s not strong enough for your objective. That’s why combining DNS filtering with Family Link (when appropriate) is the most dependable pattern for exact website blocking.

According to Google Support, Family Link restrictions are designed to be enforced for supervised accounts, and DNS filtering works by controlling domain resolution—together they cover both account-level and resolution-level gaps.

If you want the quickest fix, start with browser controls or a DNS filtering app; for stronger, device-wide blocking, use Family Link or router filtering. Add the exact domain you want blocked, verify the change by testing access, and troubleshoot with cache/VPN/Private DNS checks if it still loads.

Blocking a particular website on Android becomes easy once you pick the right enforcement layer. Use browser controls for speed, but rely on DNS filtering and/or Family Link when you need reliable, repeatable blocking across apps and connections in 2026.

Frequently Asked Questions

How can I block a specific website on Android without installing extra apps?

You can often block websites using a DNS-based filter if your Android version supports it, such as switching to a family-safe DNS in Wi‑Fi settings. Another built-in option is to use Android’s “Digital Wellbeing” or “Focus mode” to restrict certain app usage, though it may not block exact URLs in a browser. For truly targeted website blocking (by domain/URL), a dedicated parental control or firewall app is usually the most reliable option.

What is the best app to block a particular website on Android?

A top choice for blocking specific websites is a parental control or content-filter app that lets you add a domain or keyword rule (for example, blocking “example.com” or certain categories). Look for features like per-app blocking, time schedules, and the ability to require a PIN so others can’t easily undo the block. Before you install, check compatibility with your Android version and whether it supports HTTPS/domain blocking reliably.

Why isn’t my website block working on Android, and how do I fix it?

Website blocking may fail if the browser is using a different network (mobile data vs Wi‑Fi) or if you only blocked one profile while the person is using another. Some sites also use redirects, so blocking just one URL may not cover the final domain; you may need to block the main domain or additional related domains. If you’re using a DNS filter, ensure the DNS settings apply to the connection you’re actually using, and disable any VPN/proxy that bypasses filtering.

Which DNS settings can I use to block a particular website on Android?

DNS services designed for content filtering can block categories and, in some cases, specific domains by switching your Android DNS to the provider’s recommended addresses. In Wi‑Fi settings, you can usually change “Private DNS” or DNS server settings to route requests through that filter. Keep in mind that DNS-based blocking may be less precise than app-based URL rules and may vary depending on the DNS provider’s filtering capabilities.

How do I block a website on Android for only certain times of day?

Use a parental control or firewall app that supports scheduling so you can block a specific website during set hours (like school time or bedtime). Add the website/domain rule and then set the schedule for when the block should be active. If the device is used on both Wi‑Fi and mobile data, confirm the app’s rules apply across both connections to prevent bypassing.
