What is the best way to block adult websites on home Wi-Fi?

Changing the DNS settings on the router to a filtering service like CleanBrowsing or OpenDNS Family Shield is the most effective method, as it protects all connected devices simultaneously.

Will changing DNS slow down my internet?

No. Filtering DNS services like Cloudflare and CleanBrowsing have very fast response times and will not noticeably affect browsing speed.

Can VPNs bypass this blocking?

Yes. DNS-based blocking can be bypassed using a VPN. For stricter control, consider also blocking VPN usage at the router level or using parental control software as an additional layer.

Does this work with all router types?

Yes. The process is very similar across all router brands and models — the DNS settings are found under the LAN/DHCP section in virtually all routers.

Does the blocking also apply to phones connected to Wi-Fi?

Yes. When DNS is changed at the router level, all Wi-Fi connected devices are protected — including smartphones, tablets, smart TVs, and gaming consoles.

Blocking Pornographic Websites Permanently from Your Router by Changing DNS — For All Devices 2026

28/03/2026

Blocking adult and inappropriate websites at the router level is the most effective method for protecting all family members, as it applies to every device connected to the Wi-Fi network without requiring any software installation on individual devices.

How DNS-Based Blocking Works

DNS (Domain Name System) translates website names into their numerical IP addresses. By replacing your router's default DNS with a filtering DNS service, websites are blocked before they can be accessed from any device on your network — the filtering DNS simply refuses to resolve the addresses of inappropriate websites.
