Most premium VPNs now ship with a built-in ad blocker. They work at the DNS level, filtering requests to known ad, tracker and malware domains before your device ever loads them.
How VPN ad blockers work
When your device asks for the IP of an ad server, the VPN's DNS returns nothing. The page loads without the ad — no browser extension required, and it works in every app.
What they block well
Third-party trackers, malware domains, most display ads. Great as a lightweight baseline on mobile where content blockers are limited.
What they miss
In-page ads served from the same domain as the content (YouTube, Twitter, first-party sponsored posts) can't be blocked by DNS alone. Combine with uBlock Origin in the browser for full coverage.
Top providers
NordVPN's Threat Protection, Surfshark's CleanWeb, ProtonVPN's NetShield and Mullvad's DNS blockers all perform similarly in independent tests.
Frequently asked questions
QDo VPN ad blockers block YouTube ads?
No — YouTube serves ads first-party, so DNS blocking doesn't work.
QCan I use them alongside uBlock Origin?
Yes, and it's the strongest combo.
QDo they slow browsing?
No — DNS lookups actually get slightly faster.
