## Why Root-Based Ad Blocking?

Root access enables **system-level ad blocking** that surpasses traditional methods:

### ✅ **Advantages of Root Ad Blocking**

* **System-wide protection** - Blocks ads in all apps, browsers, and system components
* **No battery drain** - Unlike VPN-based blockers, hosts blocking adds no extra battery consumption
* **No network overhead** - Ads are blocked at the hosts file level before network requests
* **Works offline** - Continues working without internet connectivity
* **Fewer ad requests** - Pages and apps load without fetching ad content

### 🔄 **How Root Ad Blocking Works**

Root ad blocking operates by modifying the **hosts file** (`/system/etc/hosts`), which acts as a local DNS resolver. When an app tries to connect to an ad server:

1. The system checks the hosts file first
2. Ad domains are redirected to `0.0.0.0` or `127.0.0.1` (localhost)
3. The connection fails instantly, blocking the ad
4. Content loads without waiting for ad network requests

**Honest limits:** apps that use hardcoded DNS or DNS-over-HTTPS can bypass hosts blocking, and some first-party ads are served from the same domains as content. Pair hosts blocking with a DNS filter for those cases.

***

## Requirements

### 📱 **Device Requirements**

* ✅ **Rooted Android device** ([complete rooting guide](../rooting-guides/))
* ✅ **Magisk**, **KernelSU**, or **APatch** installed ([compare methods](../rooting-guides/root-framework-comparison.md))
* ✅ **Working root access** (verify with a terminal: `su -c whoami` should print `root`)

### 🔧 **Supported Root Managers**

| Root Manager | AdAway | Bindhosts | Notes |
|--------------|--------|-----------|-------|
| **Magisk** | ✅ Systemless | ✅ Magic mount (no WebUI) | Widest compatibility |
| **KernelSU** | ⚠️ Needs helper module | ✅ OverlayFS default, SuSFS modes | Use the systemless hosts module or AdAway Helper for AdAway |
| **APatch** | ⚠️ Needs helper module | ✅ hosts_file_redirect mode | Kernel redirect module available |

> \[!TIP]
> On KernelSU and APatch, AdAway needs the [systemless hosts module](https://github.com/symbuzzer/systemless-hosts-KernelSU-module) or [AdAway Helper](https://github.com/DEMONNICA/AdAway-Helper) to write the hosts file. Bindhosts works on all three managers without helpers.

### ⚠️ **Important Notes**

* Always know how to revert changes before proceeding
* Some banking and payment apps may require whitelisting
* OTA updates can reset direct system modifications; systemless methods survive them

***

## Method 1: AdAway (Recommended)

**AdAway** is the most user-friendly root ad blocker for Android. It writes a merged hosts file systemlessly and also offers a local VPN mode for non-rooted devices. Also available in our [ad blocker collection](../apps-and-modules/ad-blocking#ad-tracker-blocking).

### 📥 **Installation**

* **F-Droid (recommended):** [AdAway on F-Droid](https://f-droid.org/packages/org.adaway)
* **GitHub:** [AdAway releases](https://github.com/AdAway/AdAway/releases)
* Or install the APK directly with `adb install adaway.apk`

### ⚙️ **Initial Setup**

1. **Launch AdAway** and grant root permissions when prompted
2. **Choose blocking method:**
   * **Root method** (recommended on rooted devices): writes the hosts file systemlessly
   * **VPN method**: local VPN that filters DNS requests, no root needed
3. **Configure hosts sources** (see below)
4. **Apply changes** - AdAway downloads and merges the lists

### 📋 **Hosts Sources Setup**

Navigate to **Hosts Sources**. AdAway ships with defaults (AdAway hosts, StevenBlack, Peter Lowe). Valid hosts-format sources you can add:

```text
• AdAway default: https://adaway.org/hosts.txt
• StevenBlack Unified: https://raw.githubusercontent.com/StevenBlack/hosts/master/hosts
• StevenBlack with social/fakenews/gambling/porn extensions:
  https://raw.githubusercontent.com/StevenBlack/hosts/master/alternates/fakenews-gambling-porn-social/hosts
• Peter Lowe ad servers:
  https://pgl.yoyo.org/adservers/serverlist.php?hostformat=hosts&showintro=0&mimetype=plaintext
• AdGuard DNS filter (hosts format):
  https://adguardteam.github.io/HostlistsRegistry/assets/filter_1.txt
```

> \[!WARNING]
> Only use hosts-format sources. Adblock-syntax lists such as EasyList and EasyPrivacy are for browser blockers and do not work in AdAway.

### 🔧 **Optimal Configuration**

* **Enable automatic updates** in settings (daily or weekly)
* **Configure the whitelist** for apps that break when their domains are blocked
* **Check the blocked domain count** after applying to confirm lists loaded

***

## Method 2: Bindhosts (Advanced)

**Bindhosts** provides systemless hosts blocking with auto-updating, AdAway coexistence, and multiple redirect methods for stronger root hiding. Find it in our [ad blocking modules](../apps-and-modules/ad-blocking#ad-tracker-blocking).

### 🎯 **Why Choose Bindhosts?**

* **Fully systemless** - no permanent system modifications
* **Self-updating** - maintains current hosts lists automatically
* **Advanced root hiding** - SuSFS bind mounts and in-kernel redirect methods
* **Web UI management** on KernelSU and APatch (Magisk uses the action button and terminal)
* **AdAway coexistence** - can run alongside AdAway

### 📥 **Installation**

1. Download the module zip from [GitHub releases](https://github.com/bindhosts/bindhosts/releases)
2. Flash it in your root manager (Magisk, KernelSU, or APatch)
3. Reboot, then open the module action button or Web UI

### ⚙️ **Operating Modes**

Bindhosts probes the best mode automatically. You can override it in the developer options:

| Mode | Method | Root Manager | Notes |
|------|--------|--------------|-------|
| `0` (default) | Magic mount / OverlayFS + path_umount | All | Automatic; AdAway compatible on Magisk and APatch |
| `1` | SuSFS assisted bind mount | KernelSU | Requires a SuSFS-patched kernel |
| `2` | Plain bind mount | All | Highest compatibility; leaks a mount if unassisted |
| `3` | hosts_file_redirect | APatch | In-kernel redirect; requires the KPM |
| `4` | ZN-hostsredirect | All with ZygiskNext | No mount; recommended by the author |

Higher SuSFS modes (overlay, bind + spoof, source mod) exist for KernelSU. See the [official modes documentation](https://github.com/bindhosts/bindhosts/blob/master/Documentation/modes.md) for the full table.

### 🖥️ **Web UI and Terminal**

The Web UI (KernelSU and APatch) manages custom rules, sources, whitelists, and blacklists. From a root shell or Termux:

```bash
su
bindhosts                  # interactive menu
bindhosts --action         # toggle apply/reset
bindhosts --force-update   # update lists now
bindhosts --query doubleclick.net   # check a domain
bindhosts --tcpdump        # sniff active IPs (no DNS filter running)
bindhosts --custom-cron    # set update hour
bindhosts --enable-cron    # enable scheduled updates
bindhosts --force-reset    # reset the hosts file
```

### 📋 **Custom Sources**

Add hosts-format sources in the Web UI, or append them to the module's sources file, then run `bindhosts --force-update`.

***

## Configuration & Optimization

### 🎛️ **Whitelist Management**

Apps that may need whitelisting when they break:

```text
• Banking and payment apps (PayPal, Google Pay, Samsung Pay, regional banks)
• Social media (Facebook, Instagram) if feeds misbehave
• Google services (Gmail, Drive) if sync fails
• YouTube if in-app features break
```

**AdAway custom rules:** Your Lists → Allowed/Blocked Hosts.
**Bindhosts custom rules:** add them in the Web UI.

### 📱 **App-Specific Configuration**

**Chrome or WebView still showing ads on KernelSU:** open KernelSU Manager → Superuser → Chrome (and Android System WebView) and disable **Umount modules**, so the browser sees the modified hosts file.

***

## Troubleshooting

### 🔧 **Common Issues & Solutions**

#### Issue: Ads Still Appearing

1. **Confirm the blocker applied:** check the blocked domain count in AdAway or run `bindhosts --query doubleclick.net`
2. **Reboot the device** after applying
3. **Check the Chrome/WebView umount setting** on KernelSU (see above)
4. **Hardcoded DNS apps:** apps using DoH or fixed DNS servers bypass hosts blocking; use a DNS filter such as [RethinkDNS](https://github.com/celzero/rethink-app) for those

#### Issue: Apps Crashing or Not Working

1. **Whitelist the domains** the app needs in AdAway or Bindhosts
2. **Remove conflicting sources** that block content delivery networks

#### Issue: Banking Apps Fail

1. Whitelist the bank's domains
2. Configure root hiding (Zygisk denylist, Shamiko, ZygiskNext, or SuSFS)
3. Some apps still refuse to run on rooted devices; this is not fixable by whitelisting

#### Issue: Slow Browsing

1. **Reduce sources:** fewer, focused lists beat many large ones
2. Remove duplicate sources that overlap heavily

### 🔍 **Diagnostics**

```bash
# Verify root works
su -c whoami

# View the effective hosts file
su -c head /system/etc/hosts

# Check whether a domain is blocked (bindhosts)
bindhosts --query doubleclick.net
```

## Advanced Tips

### 🔐 **Malware and Tracker Blocking**

Hosts lists focus on ads. For malware and phishing, pair your blocker with a DNS filter (RethinkDNS, AdGuard DNS, or NextDNS), or use StevenBlack's alternate lists that bundle the social tracking extension.

### 🔄 **Backup and Restore**

* **AdAway:** use the built-in backup/export in settings
* **Bindhosts:** settings and sources live in the module folder under `/data/adb/modules/bindhosts/`

### 🧩 **Complementary Root Tools**

* [ForceDNS Cloudflare](https://github.com/LuferOS/forcedns_Magisk-kernelsu) - forces all DNS traffic to Cloudflare via iptables
* [AdGuard Home for Root](https://github.com/twoone-3/AdGuardHomeForRoot) - runs a full DNS filter on the device

## FAQ

### ❓ **Frequently Asked Questions**

**Q: Will ad blocking affect app functionality?**
A: Most apps work normally. Whitelist domains for apps that rely on blocked networks.

**Q: Can I run AdAway and Bindhosts together?**
A: Bindhosts supports AdAway coexistence, but a single active hosts writer avoids conflicts. Do not run two hosts writers in competition.

**Q: Do I need to update hosts files manually?**
A: AdAway has a built-in auto-updater, and Bindhosts self-updates on a schedule. Manual updates are a fallback.

**Q: Will this work with a VPN?**
A: Yes. Hosts-based blocking operates below the VPN layer and works alongside VPN apps, unlike VPN-slot blockers.

**Q: How much storage do hosts files use?**
A: Typically 1-3 MB depending on the sources. Very large lists can slow DNS lookups slightly.

**Q: Does this work on mobile data?**
A: Yes, hosts blocking applies to Wi-Fi and mobile data alike.

**Q: Will OTA updates remove ad blocking?**
A: Systemless methods (AdAway root mode, Bindhosts) survive OTA updates. Direct writes to `/system` do not.

**Q: What about non-root ad blocking?**
A: See the [non-root alternatives guide](../non-root-alternatives.md) for Private DNS, RethinkDNS, browser extensions, and patched apps.
