How to Block Porn

DNS, router, browser, device, and accountability options, with the bypasses worth planning for.

answer

Quick answer

Use layers. Set family DNS on the router, lock device restrictions, turn on browser Secure DNS, and add a blocker for the device you use most. DNS alone can be bypassed by mobile data, VPNs, and browser DNS-over-HTTPS settings.

Use these for adult-content and malware filtering. Put router settings first if you want the whole home Wi-Fi covered.

Which DNS setting should you change?

Change thisUse it whenLimitation
RouterYou want adult-content filtering on home Wi-Fi for every device.It does not cover mobile data, VPNs, hotspots, or other Wi-Fi networks.
PhoneYour phone is the main bypass or you use mobile data.iOS manual DNS is per Wi-Fi network; Android Private DNS is more direct.
Mac or WindowsA laptop leaves home, uses different Wi-Fi, or bypasses router DNS.Settings can be per network, adapter, or browser.
Browser Secure DNSChrome, Edge, or Firefox ignores the router DNS.A browser can still be changed back unless settings are locked.

Device DNS instructions

Start with the router if you control it. Then set the phone, because mobile data is the common gap. Add Mac or Windows settings if the computer travels or uses a browser-level bypass.

01

Router

  1. Open your router app or admin page. Look for Internet, WAN, LAN, DHCP, or DNS settings.
  2. Set DNS to 1.1.1.3 and 1.0.0.3. Add the IPv6 addresses if your router has IPv6 DNS fields.
  3. Save, restart the router if needed, then reconnect devices to Wi-Fi.

Router menus vary. If DNS is locked by your ISP router, use device-level settings or put your own router behind it.

steps

Browser Secure DNS

Chrome or Edge

Open Privacy and security, find Secure DNS, then choose a custom provider and use https://family.cloudflare-dns.com/dns-query.

Firefox

Open Privacy & Security, find DNS over HTTPS, then use the custom provider URL https://family.cloudflare-dns.com/dns-query.

If router DNS stops working

Check the browser first. Secure DNS can override the router and make it look like the router settings failed.
