### Short Introduction

Want to block harmful websites and malware without buying expensive software? You can easily protect your home network using DNS filtering with free, family-safe services like Cloudflare or OpenDNS. This method works on all connected devices without needing to configure each one.

### Simplified One-Line Flowchart

- Change router DNS ➔ Use family-safe DNS (Cloudflare/OpenDNS) ➔ Block adult & malicious sites for every connected device

### Easy Step-by-Step Method

**Step 1: Use Cloudflare Family DNS (Easiest)**

- Open your router settings (usually at `192.168.0.1` or `192.168.1.1`).
- Look for DNS settings and enter these:
  - Primary DNS: `1.1.1.3`
  - Secondary DNS: `1.0.0.3`

- These block malware and adult sites automatically.

**Step 2: Use OpenDNS (Customizable Control)**

- Create a free account: [https://www.opendns.com/home-internet-security](https://www.opendns.com/home-internet-security)
- Set your router’s DNS to:
  - Primary: `208.67.222.123`
  - Secondary: `208.67.220.123`

- Log in to OpenDNS dashboard to block specific categories/websites.

**Step 3: (Optional) Set Device-Specific DNS**

- For kids’ devices, override system DNS with family-safe options if they try to bypass router settings.

**Step 4: (Optional Advanced) Use Pi-hole or Firewalla**

- For deeper blocking and monitoring, set up:
  - [Pi-hole](https://pi-hole.net/)
  - [Firewalla](https://firewalla.com)

### Quick Tips (Optional)

- Write down original ISP DNS before changing settings.
- Test by visiting blocked websites (e.g., adult content or known malware pages).
- Combine DNS filtering with a strong parental approach for better results.

### Important Notes

- Tech-savvy kids can bypass DNS with VPNs or mobile data.
- Consider combining DNS filtering with supervision and conversation.
- Some DNS filters may mistakenly block useful sites—use a whitelist if needed.
- If using Microsoft Family Safety, ensure the child has a non-admin Windows account.
