Pi-hole — Network-wide ad blocking via DNS — every device on your LAN, no extensions needed
What it is
Pi-hole is a network-level ad blocker: it acts as your LAN's DNS server and drops requests to advertising and tracking domains for every device, with a dashboard showing what was blocked. It is free and runs on minimal hardware. It blocks ads inside apps and on TVs where browser extensions cannot reach, but it cannot stop ads served from the same domain as the content, and a misconfigured DNS setup can confuse a whole network.

Long-form introduction by the BetterPicker editors · checked against the official site · Oct 8, 2026
Pi-hole is a DNS sinkhole for your whole network: point your devices at it and ads stop loading on phones, laptops, televisions, and consoles, with no client software anywhere. It is free and open source under the EUPL, runs on a Raspberry Pi or any Linux box, and the v6 line installs in minutes through a guided dialog. As an ad blocker it is broad but blunt: DNS-level blocking cannot separate an ad from content on the same domain, so a dashboard habit and occasional exceptions are part of the deal.
What it does well
One install shields every device. Blocking happens at DNS, so televisions, game consoles, smart speakers, and phones without ad blockers all benefit. The project's own materials call out mobile apps and smart TVs, exactly the screens traditional browser blockers cannot reach. Guest devices get protected the moment they join the network.
The dashboard makes DNS visible. Every query lands in live graphs and long-term logs, so you can see which device phones home at three in the morning and whitelist with precision. That insight turns a blocking utility into a working map of your household's network chatter.
It is light and flexible. Minimal hardware requirements suit a decade-old Raspberry Pi, it can double as your network's DHCP server, and the project documents capacity for hundreds of millions of queries. Community blocklists tune the policy anywhere from strict to gentle in a few clicks.
Who it's for
Home lab hobbyists, privacy-minded households, and tinkerers with a spare single-board computer are the natural audience. It fits people comfortable changing a router's DNS settings once and reading documentation occasionally when something odd happens. It fits poorly if you want a zero-touch appliance, if your household tolerates zero breakage, or if you cannot spare a small always-on box. Small offices use it the same way hobbyists do, just with a change-control habit.
Where it falls short
DNS blocking is blunt by nature. Ads served from the same domains as the content they wrap cannot be blocked without breaking the page, and platforms that serve ads from first-party domains slip through. Pi-hole shrinks the ad load dramatically; it does not sterilize the web.
Setup touches your network. You will change DNS settings on a router or on each device, and a misconfiguration can confuse connectivity for the whole household. Reserving an IP address and picking a reliable host are part of the job, not optional extras.
Some things break until taught. Captive portals, smart-home apps that insist on vendor domains, and workplace VPNs can stumble behind aggressive blocklists. Someone in the house needs to read the query log and add exceptions when a screen goes blank.

Frequently asked questions
▸What is Pi-hole?
Pi-hole is a DNS sinkhole that blocks ads for every device on your network. You install it on Linux hardware, point your router or devices at it for DNS, and it refuses to resolve known advertising and tracking domains. A web dashboard shows every query.
▸Does Pi-hole block YouTube ads?
Mostly no. YouTube serves ads from the same domains as the videos themselves, so DNS-level blocking cannot remove them without breaking playback. Pi-hole is strong against third-party ad networks and trackers, which is still the majority of the web's ad load.
▸Is Pi-hole really free?
Yes. Pi-hole is open source under the EUPL and free to use, funded by donations. There is no premium tier; the blocklists that feed it are community projects, and hardware costs are whatever a small always-on computer costs you.
▸What hardware do I need?
Any small always-on computer running Linux: a Raspberry Pi is the classic choice, and Docker containers work on existing servers. Requirements are modest, since DNS lookups are lightweight, but the device must stay on for blocking to keep working.
