Back in our day, the solution to too much screen time or risky online behaviour was simple: take the device away. But that doesn’t really work anymore. Today, technology is part of how children learn, do homework, socialise, and even play.

The smarter approach isn’t to deny access but to make it safer. That’s where DNS filtering comes in. It’s one of the simplest, most effective ways to protect children online, without turning your home into a digital battlefield.

What Exactly Is DNS?

DNS stands for Domain Name System. Think of it as the internet’s phonebook. When you type a web address like parentsafrica.com, DNS translates it into a digital address your device can understand and connect to. But this simple process also provides a clever way to filter what gets through.

A DNS filter works by checking every site before it loads and blocking unsafe or inappropriate ones, from adult content and gambling to malware and scams.

It acts quietly in the background, like a digital fence between your child and the wilder parts of the internet. The internet is not meant to be consumed without filtering.

Types of DNS and How They Work

There are two main types of DNS setups that you can use as a parent, and both have their strengths:

1. Router-Level DNS

This is the most common method for home use. You set up DNS filtering directly on your Wi-Fi router, which means every device connected to that network, whether it’s laptops, tablets, phones, or smart TVs, gets protected automatically.

In Nairobi, most routers from Safaricom Home Fibre, Zuku, and JTL Faiba allow you to update DNS settings easily through your browser. Once configured, the filter runs quietly, with no apps to install and no subscriptions needed.

Setup takes about 10–15 minutes, and for most families, that’s all you need to cover everyone in the house. But the question is, what about when they are not in the house? Holidays are coming up, and all that means is that we are in the house less as a family, so how do we stay safe then?

2. Software or Device-Level DNS

This version protects your child even when they’re not at home. You install DNS filtering software or an app directly on their device. That means the same protection follows them when they’re using school Wi-Fi, mobile data, or visiting friends.

It’s a great choice for older kids who carry their own phones or laptops. Services like NextDNS or CleanBrowsing let you manage settings remotely and see which sites are being blocked or accessed.

For many families, combining both types, router-level for home and device-level for mobile use,  gives the best balance between safety and flexibility.

Which Type Is Better?

That depends on your family setup:

If your kids mainly use the home Wi-Fi for schoolwork or entertainment, router-level filtering is perfect. It’s easy, reliable, and doesn’t require ongoing management.

If they’re more independent, switching between mobile data, friends’ networks, or school computers, then software DNS ensures consistent protection wherever they go.

Either way, both are affordable and effective. Most DNS services are free, and premium ones cost less than KES 1,000 per month, a small investment for peace of mind.

Set Up Once, Stay Protected

Contact your local internet provider to guide you through setting up a DNS for your router.

The best part about DNS protection is that it can grow with your child. You can create profiles for different ages:

Ages 6–10: Strict filtering; block adult content, YouTube comments, gaming sites, and chat rooms.

Ages 11–14: Allow educational sites and communication tools but block gambling, violence, and explicit content.

Ages 15–18: Light filtering, with focus on security and safe social media use.

Each profile helps balance freedom and safety without making kids feel overly restricted.

Kenya’s Data Protection Act (2019) requires parents and institutions to handle children’s data responsibly and in their best interests. Section 33 specifically states that no child’s data should be processed or exposed without consent from a parent or guardian.

By using DNS filtering, you’re actually supporting these laws. The system limits unnecessary data collection, promotes privacy, and gives parents more control over what’s happening online — without invading a child’s space or monitoring every move.

A 2025 study published in SCIRP, “Leveraging DNS Filtering to Safeguard African Children from Harmful Internet Content,” also found that properly configured DNS systems help African families and schools protect minors online while staying aligned with local data and privacy frameworks.

But remember, no system can catch everything. Kids are smart, and technology evolves fast. DNS filters block a lot, but not all. That’s why this should be seen as the first step, not the final solution.


Regular conversations about online safety, responsibility, and what to do when they encounter inappropriate content are just as important as any technical setup.

Protecting your child online doesn’t have to mean hovering over their shoulder or cutting them off from the internet.
Setting it up takes minutes, is affordable, and offers peace of mind that’s hard to put a price on.

As parents, we can’t always be there when they go online, but we can make sure they’re surrounded by the right digital guardrails. It’s about teaching them how to be online safely and setting up the right guardrails to help them along the way. DNS is a smart place to start.

In a world where children are growing up digital, the best kind of protection isn’t control, it’s smart, informed care.
