How do I configure my home router to block adult sites and force SafeSearch across all devices? Is network-level DNS filtering enough to protect young children, or do I need to combine it with other software?

Router DNS filtering is an excellent first line of defense to block explicit websites, but it cannot manage specific apps or individual video channels. To set it up, log into your router and change WAN DNS to CleanBrowsing (185.228.168.168) or OpenDNS (208.67.222.222). For granular control (like whitelisting educational YouTube channels), you must combine router filters with device-level parental controls like WhitelistVideo.

OpenDNS vs CleanBrowsing vs Router Controls: Whole-home safety setup guide

Hi everyone,

I have an 8-year-old and a 6-year-old. They are starting to use school-issued Chromebooks and family tablets for school assignments around the house. I want to make sure they cannot accidentally access explicit websites, regardless of what browser or device they are holding.

I have an ASUS RT-AX86U router. I keep hearing about network-level filters like OpenDNS and CleanBrowsing, but I'm not sure which one is better, or how to configure them on my router settings.

Could someone walk me through the configuration? And is a router-level DNS filter enough to keep them safe, or should I be doing more at the individual device level?

This is the exact right question to ask. Router-level controls are the first line of defense for any modern home. It secures smart speakers, game consoles, and school laptops that you can't install third-party tracking apps on.

Between the options, I highly recommend CleanBrowsing (Family Filter) over OpenDNS for young kids. Why? CleanBrowsing forces Google, Bing, and YouTube into strict SafeSearch mode at the DNS layer automatically. OpenDNS can do this, but configuring it requires a custom account, installing an IP-updater script on your computer, and manually setting up certificates—it's a headache if you have a dynamic IP from your internet provider. CleanBrowsing is set-it-and-forget-it.

Here is how to set it up on your ASUS RT-AX86U router in 3 minutes:

Open a web browser and go to your router admin panel at http://192.168.50.1 (ASUS default). Log in with your admin credentials.
In the left sidebar, click on LAN under Advanced Settings, then click on the DHCP Server tab at the top.
Scroll down to the DNS and WINS Server Setting section.
In the DNS Server 1 field, enter CleanBrowsing's primary IP: 185.228.168.168
In the DNS Server 2 field, enter the secondary IP: 185.228.169.168
Click Apply at the bottom of the page. Your router will reboot its DHCP service.

(Tip: To prevent tech-savvy kids from bypassing this by typing in custom DNS settings on their iPads, navigate to WAN -> Internet Connection -> scroll down to "DNS over HTTPS" or "DNS Filtering" on your ASUS, and enable a rule that forces all outbound port 53 traffic through your router's DNS).

Is this enough? No. DNS is a blunt instrument.

DNS filters are purely "binary"—they either allow a whole domain or block it. CleanBrowsing can block youtube.com entirely, but it cannot block *specific channels* or *individual videos*. If YouTube is allowed (which your kids will need for school), CleanBrowsing SafeSearch filters out explicit videos, but it still allows the mindless recommendation sidebar, dangerous YouTube Shorts, and violent gaming streams.

To secure YouTube for young kids, you must pair your network-level DNS filter with a device-level whitelisting tool like WhitelistVideo. It lets you block YouTube entirely at the network layer for general browsers, and only let them access YouTube via the WhitelistVideo app/profile, where you have personally approved channels (like Wild Kratts or Numberblocks) while Shorts, comments, and sidebars are completely disabled.

Think of Router DNS as the secure fence around your yard, and WhitelistVideo as the locked playpen inside for young kids!
