Your App Has an Ad?
Not Anymore.
AdShield is a local DNS-based ad blocker for Android.
It blocks ads, trackers, and malware across every app on your phone — 100% on-device, no root required.
Blocked: ads.doubleclick.net
What happened
App com.social.network attempted to load an ad from ads.doubleclick.net. AdShield intercepted the DNS query and returned NXDOMAIN — the ad never loaded.
Why it was blocked
The domain ads.doubleclick.net is in AdShield's ad network blocklist. The app continues to work normally — ad SDKs handle failed loads gracefully by design.
- DNS query blocked locally, 0 bytes sent to ad server
- App continues working without interruption
- Background data saved from ad payload

How AdShield Works
Three invisible steps between you and an ad-free experience.
Activate
Tap to create a local VPN tunnel on your device. No remote servers involved — your traffic stays entirely on your phone.
Intercept
Every DNS query from any app is checked against 150+ known ad, tracker, and malware domains in real-time.
Block
Matched domains get an NXDOMAIN response — the ad simply doesn't exist. Your app keeps working perfectly.
System-Wide Protection
Blocks ads across all apps and browsers — games, social media, news readers, everything on your phone. Not just one browser.
Zero Performance Impact
Only tiny DNS packets (~100 bytes) are processed. All your actual traffic — downloads, streaming, browsing — flows untouched.
Only DNS queries are routed. TCP/UDP data flows directly through the normal network interface.

Frequently Asked
Honest answers. No marketing fluff.
01Does AdShield require root access?
No. AdShield uses Android’s built-in VpnService API to create a local network tunnel. No root, no unlocked bootloader, no modifications needed. Works on any device running Android 7.0 or later.
02How does AdShield actually block ads?
AdShield creates a local VPN that only routes DNS traffic. When any app requests an ad domain, AdShield intercepts the DNS query, checks it against 150+ known ad and tracker domains, and returns an NXDOMAIN (domain not found) response. The ad simply never loads, but the app continues working normally.
03Will it slow down my phone or drain battery?
No. AdShield only processes tiny DNS packets (~100 bytes each). All your actual internet traffic — downloads, streaming, browsing — flows through the normal network path completely untouched. Battery impact is negligible.
04Does AdShield collect any of my data?
Zero. Everything is processed locally on your device. No data is sent to any external server, no analytics, no account required. Your browsing activity stays entirely private.
05Can AdShield block YouTube ads?
No. YouTube serves ads from the same domain (googlevideo.com) as the actual video content. Blocking that domain would also block the video. AdShield is most effective against third-party ad networks that serve ads from separate, identifiable domains.
06Which Android versions are supported?
Android 7.0 (Nougat) and above — covering the vast majority of active Android devices worldwide.
