How to Block Porn Sites

Protecting devices from access to adult explicit content is an increasingly critical need, whether to protect minors, improve concentration and digital well-being, avoid malware risks or maintain safer browsing. There are multiple effective methods: from home router settings, DNS filters, browser extensions and parental control apps that make your life easier. Below is a comprehensive and fully updated step by step guide. Let's get started :)

Why Learn How to Block Porn on the Internet?

Blocking access to pornographic sites is not only a parental control measure. It also helps reduce digital risks and improve the quality of Internet use. Pretty common reasons include:

🔒 Child protection

Children are accessing the Internet at increasingly younger ages. Accidental exposure to pornography can be harmful, affect their emotional development, cause anxiety and generate inappropriate curiosity.

🛡️ Digital security

Many pornographic sites contain:

• Malware disguised as videos or pop-ups
• Phishing that impersonates premium pages
• Ads that redirect to scams
• Scripts that attempt to steal data. Blocking them prevents infections and attacks.

🧠 Control of habits and digital well-being

Some users seek to block these sites to reduce impulses, avoid distractions or reinforce healthy habits. Communicate to seek help.

🏠 Family-level filtering

In shared households, blocking inappropriate content prevents accidental access on televisions, tablets or shared devices.

How to Block Porn Sites at the Internet Level

Blocking content from the network before it reaches the device is one of the most efficient alternatives. This allows you to protect all Wi-Fi devices without individual configuration.

How to Block All Porn Using Your Wi-Fi Router

This method is ideal for families, schools or any place where you want complete protection. The steps below generally work on Asus, TP-Link, Huawei, Netgear, Movistar, Orange and Vodafone routers, etc :)

1. You must be connected to the router to access its settings.
2. Enter the router address into your browser's address bar:

• 192.168.1.1
• 192.168.0.1

3. Log in with the administrator username and password (usually: admin; usually pasted on your router).
4. Go to the Parental Control settings or Security section
5. The section you're looking for is usually:

• Parental Controls

6. Enable "Block websites by category." Some routers (Asus, TP-Link Archer, TP-Link Deco, Netgear Nighthawk) block websites by category:

• Adult content
• Gambling
• Violence

7. Select the category you want to block - The router automatically blocks porn-related domains. Just choose:

• Adult Content
• Pornography
• +18 websites

8. Save changes and restart the router.

Using DNS Filters to Block Porn from Internet

• CleanBrowsing Family Filter 185.228.168.168 and 185.228.169.168 blocks adult content & provides a safer browsing experience.
• OpenDNS FamilyShield 208.67.222.123 and 208.67.220.123 block adult content & other categories of websites.
• Cloudflare Family (1.1.1.3) 1.1.1.3 1.0.0.3, blocks malware & adult content.

How to configure them on the router (recommended)

1. Access the router's IP address (192.168.0.1 or 192.168.1.1)
2. Look for Network / Internet / WAN / DNS.
3. Replace the DNS with the DNS settings for the chosen service.
4. Save and restart.

SafeSearch makes it less complicated since it automatically filters explicit images, videos and results.

2. Go to the “SafeSearch filters” section.
3. Enable: Filter explicit results.
4. Scroll down and click Save.

Bing

How to Completely Block Porn: Advanced Methods

These methods are designed for when you want protection or when a minor tries to bypass restrictions. However, we must note that no solution is 100% bypass-proof. For this, combining several of them is a brilliant idea :)

How to Prevent Porn Access with VPNs and Proxy Restrictions

Some people try to use VPNs or proxies to bypass blocks. You can prevent this as follows:

On your router:

1. Disable VPN Passthrough.
2. Block VPN ports - 1194, 1701, 500, 4500, 51820.
3. Enable Block VPN applications option if possible.
4. Force DNS through your filtered provider (Cloudflare 1.1.1.3 or CleanBrowsing).
5. Block DNS-over-HTTPS (DoH) and DNS-over-TLS (DoT), if possible.

On mobile devices:

Enable Android Family Link or iOS Screen Time to enable supervised mode, as this will prevent the installation of VPN apps, changes to DNS settings, and the use of private DNS (Android devices) and VPN profiles (iPhone iOS).
