What is ShieldDNS?

ShieldDNS is an Android app that filters DNS requests locally to reduce ads, trackers, and unwanted background connections across your device.

DNS-Based Filtering

When an app tries to connect to a known ad or tracking domain, ShieldDNS blocks the DNS request before the connection is made. No data leaves your device through our servers.

Works Across Apps

Unlike browser extensions that only work inside one browser, ShieldDNS can filter DNS requests from many apps and browsers at the same time.

Lightweight Protection

DNS filtering only intercepts name lookups — it does not route all your internet traffic through a remote server. This keeps the app fast and battery-friendly.

No Root Required

ShieldDNS uses Android's built-in VPN service to intercept DNS traffic locally. You do not need to root your device or install any system-level modifications.

Why DNS Ad Blocking?

No Root

Works without rooting your Android device. Safe and simple.

System-Wide

Filters DNS requests across many apps, not just one browser.

Lightweight

Does not tunnel all traffic — only DNS lookups are intercepted.

How It Works

Get started in minutes — no technical setup needed

1

Download ShieldDNS

Install the ShieldDNS app from Google Play on your Android device.

2

Open the app and enable protection

Tap the enable button. Android will ask for VPN permission — this is how ShieldDNS intercepts DNS requests locally.

3

Browse with fewer unwanted connections

ShieldDNS runs in the background and filters DNS requests from apps and browsers on your device.

What ShieldDNS Can and Cannot Block

We believe in transparency. DNS-based filtering is powerful but has limitations.

Can reduce or block

  • Many ad domains from known blocklists
  • Tracking and analytics domains
  • Unwanted background connections
  • Known malware and phishing domains
  • Third-party ad networks with dedicated domains

!Cannot block

  • Same-domain ads (ad served from app's own domain)
  • Most YouTube ads (served from Google domains)
  • First-party ads built into app content
  • Sponsored content embedded in apps
  • Ads that do not use separate DNS domains

Frequently Asked Questions

Is ShieldDNS a VPN?

ShieldDNS uses Android's VPN service to filter DNS requests locally. It is not a traditional VPN and does not tunnel all internet traffic through a remote VPN server. Your IP address does not change.

Does ShieldDNS block all ads?

No ad blocker can block every ad. ShieldDNS can block many ads and trackers that use known domains, but some ads are served from the same domain as app content and cannot be blocked by DNS filtering.

Does ShieldDNS block YouTube ads?

DNS-based blocking may reduce some unwanted connections, but it cannot reliably block all YouTube ads because many are served from the same domains as video content.

Does ShieldDNS require root?

No. ShieldDNS works without root using Android's built-in VPN permission.

Does ShieldDNS work on Wi-Fi and mobile data?

Yes, ShieldDNS can work on both Wi-Fi and mobile data when protection is enabled.
