What is DNS Filtering?

DNS filtering is a network-level content control that blocks access to websites and online services by intercepting domain name requests before they resolve. By pointing your home router to a family-safe DNS provider, you can block inappropriate content across every device on your network without installing software on each device.

Why It Matters for Families

DNS filtering covers devices that don't support traditional parental control apps — smart TVs, gaming consoles, and guests' devices on your network. It's one of the most underused yet effective network-level protections available to families.

Warning Signs to Watch For

  • 1Gaming consoles, smart TVs, or other devices in your home have no content filtering
  • 2Your child accesses content on devices you didn't think to restrict

What You Can Do

Set up a family-safe DNS provider (CleanBrowsing, NextDNS, or OpenDNS) in your router's network settings. This takes about 10 minutes and doesn't require installing software on individual devices. NextDNS offers detailed logging so you can see what domains devices on your network are accessing.

Content Filter
A content filter is a tool or service that blocks access to specific types of content — websites, apps, or material — based on rules or categories. Filters can operate at the app level, device level, or network level (router or DNS), and range from keyword blocking to AI-powered content classification.
Safe Search
Safe search is a setting in search engines that filters out explicit content — including adult images, videos, and websites — from search results. Google, Bing, and DuckDuckGo all offer safe search settings, and some routers and DNS services can enforce safe search network-wide.
Parental Controls
Parental controls are tools that allow parents to manage and restrict their child's access to content, apps, features, or screen time. They range from built-in device features (like Apple Screen Time or Google Family Link) to app-level controls offered by individual platforms.
