The Nuclear Option: How to Hard-Block Porn at the Network Level

You installed a blocker on your phone. Then you deleted it. You installed a browser extension. Then you disabled it.

If you are technical, you know that "software" blockers are easy to bypass. You need a "Hardware" or "Network" level block.

This guide covers the 3 best DNS (Domain Name System) blockers in 2025. These block porn before it even reaches your device.

Option 1: NextDNS (Best for Customization)

• Pros: Highly customizable, analytics, can block specific apps (e.g., TikTok, Instagram).
• Cons: Requires account setup.
• Setup:
  1. Create free account at nextdns.io.
  2. Go to "Privacy" tab -> Add "OISD" blocklist (blocks ads + porn).
  3. Go to "Parental Control" -> Enable "Pornography".
  4. Change your Router's DNS IP to the one NextDNS gives you.

Option 2: Cloudflare Family (Easiest / Fastest)

• Pros: Zero setup, fastest speed (1.1.1.1 infrastructure).
• Cons: No whitelisting. It's all or nothing.
• IP Addresses (IPv4):
  • Primary: 1.1.1.3
  • Secondary: 1.0.0.3

Option 3: OpenDNS Family Shield (The Classic)

• Pros: Been around forever, very stable.
• Cons: Slower than Cloudflare.
• IP Addresses:
  • Primary: 208.67.222.123
  • Secondary: 208.67.220.123

The "Psychological" Gap

DNS blocking is powerful, but it has one flaw: You have the admin password to your router.

If you are truly addicted, you will find a way to switch the DNS back. This is why "Tech" alone fails.

• Tech (DNS) stops the accidental peek or the "doomscroll."
• Psychology (Halto) stops the urge that drives you to hack your own router.

Recommendation: Use NextDNS for the network + Halto for the brain.
