Add your comment and screenshots

An ad bypassed AdGuard public DNS filtering in the Android app Angry Birds 2 (com.rovio.baba).

The ad appeared as a full-screen black interstitial. Using Rethink DNS, I can see the connection was made directly to IP 34.160.81.0 (US, Google Cloud) over TCP/443 (HTTPS) — no domain name was used, which is why DNS filtering could not block it.

Device: Samsung Galaxy A36 (Android)
DNS: dns.adguard-dns.com via Android Private DNS (no AdGuard app or AdGuard Home)
Time of incident: approx. 07:00:42

Please consider adding 34.160.81.0 to the IP blocklist.

I want to add that only the ad container was actually shown not the full ad

Update: the ad appeared again and this time the ad creative was visible,
confirming 34.160.81.0 is an active ad server for Angry Birds 2. It has
now contacted this IP 5 times according to Rethink DNS firewall logs.

Update: This ad network is using rotating CDN IPs across multiple
cloud providers, not just a single fixed IP. In addition to 34.160.81.0 (Google
Cloud), I've also observed 99.84.41.105 and 3.167.192.68 (both Amazon
CloudFront) getting ads for Angry Birds 2.

Blocking individual IPs is not effective since the ad network fails over to
other addresses on the same CDN. Since these are shared CDN ranges (not
dedicated to one ad network), IP-level blocklisting may block other traffic. If possible, identifying the
specific ad SDK domain used by Angry Birds 2 (likely via TLS SNI/ClientHello
inspection) would be a more durable fix than IP blocking.

Now I'm getting full ads with the X appearing only after a full wait. This is not what I use this dns for. Can someone please fix this issue as it directly defeats the purpose of adguard dns
