Parents' guide — Router blocking

How to block websites on your home Wi-Fi router (2026)

Blocking websites on your home Wi-Fi router filters the sites that every device in the house can reach, all at once. This guide shows you the exact steps: logging in to your router, using its block list, and the easier route for most families, switching to a free family-filtering DNS. It is also honest about the big gaps, so you are not caught out.

The short answer

Log in to your router's admin page in a web browser, find Parental Controls or Access Restrictions, and add the sites you want blocked. For most families the simpler and more powerful option is to change the router's DNS to a free family-filtering service, which quietly blocks adult and malware sites for every device on your Wi-Fi at once.

Both methods protect every phone, tablet, console and laptop on the home Wi-Fi. Neither does anything once a phone leaves the house or switches to mobile data.

Step by step

1. Log in to your router

Open a web browser on a device connected to your Wi-Fi. In the address bar, type your router's address. The most common ones are 192.168.0.1, 192.168.1.1, or routerlogin.net for Netgear. The address and the default password are usually printed on a sticker on the router itself.

Sign in with the admin username and password. If you have never changed these, use the ones on the sticker, then change the password straight away so your child cannot simply undo your settings. Keep the new password somewhere safe.

2. Use the built-in block list

Once you are in, look for a menu called Parental Controls, Access Restrictions, URL Filtering or Website Blocking. The exact name depends on the make (TP-Link, BT, Sky, Virgin, Netgear and others all word it differently).

• Open that menu and find the block list or blocked sites box.
• Type in the web addresses you want blocked, one at a time.
• Save or apply. The block takes effect for the whole home within a minute or two.

This is fine for a short, specific list. It becomes hard work if you are trying to block the whole adult internet by hand, because there are millions of sites. That is where DNS comes in.

3. The easier route — change the router's DNS

DNS is the internet's phone book. It turns a name you type, like a website address, into the number a computer needs to find it. If you point your router at a family-filtering DNS, that phone book simply refuses to look up adult and malware sites for everyone on your Wi-Fi. You set it once and it covers every device.

In your router settings, look for Internet, WAN, DHCP or Network, then a field for DNS servers. Replace the two addresses there with one of the free family services below, save, and restart the router.

All three are free and block adult content automatically. Cloudflare for Families and CleanBrowsing also block known malware. Pick one, enter both of its addresses, and you are done for the whole house.

4. Or use your broadband provider's filter

In the UK, most broadband providers offer free network-level parental controls you can switch on from your online account, with no router settings at all. BT, Sky, Virgin Media, TalkTalk, EE and Plusnet all have one. It is a one-tap alternative that filters adult sites across your whole connection, and it is often the simplest place to start.

What the free tools do and where they stop

Router blocking, family DNS and ISP filters are genuinely useful and cost nothing. But it is honest to know their edges, because the gaps are large.

• Mobile data bypasses it completely. The moment a phone switches off your Wi-Fi to 4G or 5G, none of these filters apply. The child browses freely.
• It stops at your front door. At a friend's house, at school, on public Wi-Fi or anywhere else, your home settings do nothing.
• A VPN or a changed DNS slips past it. If a phone sets its own DNS, or runs a VPN, it ignores the router. Many phones now use encrypted DNS by default, which can route around home filters.
• It is all-or-nothing for the house. A router filter affects the adults too, unless you set up a separate guest network or per-device rules for the children only.
• It blocks sites, not what is said. It cannot see the words inside a chat, a game or a message. It filters whole websites, nothing more.

Android and iPhone both obey your home Wi-Fi and DNS in exactly the same way. The difference is only in what a phone-level app can add on top. For controls that travel with the child, read our guide to Apple Screen Time for iPhone, or Android parental controls without Family Link for Android.

Where Safeinest helps — and where it cannot

A router filters your home. A phone app travels with the child. Safeinest is a paid family app that fills the gap the router leaves, and it is honest that this depends on whether your child carries an Android phone or an iPhone.

On an Android child phone, Safeinest can set app pauses, bedtime and school-hours rules, daily and per-app limits, live location, safe zones and a removal lock, and it works on mobile data and away from home, not just on your Wi-Fi. It can also send message-safety alerts, spotting self-harm, bullying or grooming words in messages and notifications, on the device, with a consent screen the child sees. There is also a Safeinest Browser with SafeSearch and blocked sites.

On an iPhone, Apple does not let any app read messages, so Safeinest cannot do that, and we will not pretend otherwise. On iPhone it does limits, location, family calls, an SOS button, and picture warnings through Apple's own tools. The rule of thumb is simple: iPhone means limits yes, reading messages no. No app can read WhatsApp or iMessage on an iPhone. See the full, honest list on our features page.

The numbers

Children get phones early, and they carry them out of range of your router. Ofcom (2025) found that 56% of 10-year-olds and 83% of 11-year-olds in the UK own a smartphone, and 99% of 8 to 17-year-olds are online. Most of those phones are Android. StatCounter puts Android at about 70% of phones worldwide, and far higher in many countries, around 94% in Pakistan and 96% in India (World Population Review and StatCounter, 2024 to 2025).

The harder truth is what a website filter never sees. In Europe and Canada, the WHO/Europe HBSC study (2024) found 1 in 6 children aged 11 to 15 has been cyberbullied. And when something bad happens online, 2 in 5 children never told anyone (LGfL, via Internet Matters). A router can block a site, but it cannot see a cruel message or help a child who stays silent. If your child has already seen something they should not have, our guide on what to do when a child saw something adult online can help.

What to say to your child

Keep it calm and open. You could say: "I have put a filter on our home Wi-Fi so some grown-up websites do not pop up by accident. It is not about spying on you." Then add the line that matters most: "If you ever see something online that scares or upsets you, you can tell me, and you will not be in trouble." Saying that early makes it far more likely they will come to you.

Helplines

In the UK, your child can call Childline free on 0800 1111. As a parent you can call the NSPCC on 0808 800 5000. In an emergency, always call 999. Outside the UK, call your local emergency number or your country's child helpline.
