VPN & Proxy Detection — GermanyDetect VPN, Proxy & Bot Traffic from Germany
Maskbreak scores every visitor's network in real time — flagging VPN exit nodes, residential proxies, datacenter ASNs, and headless browsers originating from Germany. Free API. Under 40ms server-side. No CAPTCHAs.
The networks Germany traffic actually arrives from
Germany has 2,580 autonomous systems on the public registry. 209 of them are hosting, cloud or transit networks holding 104.1M addresses between them — the ranges a commercial VPN or datacenter proxy exits from. Residential broadband is the rest, and that is the traffic worth watching, because a residential proxy hides inside it.
| ASN | Network | IPv4 space |
|---|---|---|
| AS3320 | DTAG Internet service provider operations | 34.1M addresses |
| AS31399 | DAIMLER-AS ITTTN Global Network | 16.8M addresses |
| AS3209 | VODANET International IP-Backbone of Vodafone | 12.8M addresses |
| AS6805 | TDDE-ASN1 | 8.4M addresses |
| AS680 | DFN Verein zur Foerderung eines Deutschen Forschungsnetzes e.V. | 7.7M addresses |
| AS24940 | HETZNER-AS | 3.2M addresses |
| AS553 | BELWUE BelWue-Koordination | 2.1M addresses |
| AS8881 | VERSATEL | 1.8M addresses |
Largest hosting-shaped networks registered in Germany, by IPv4 allocation. Registry data, refreshed daily. A datacenter ASN is not evidence of fraud on its own — it is one signal, weighed alongside device and behaviour.
Why Germany traffic needs special scrutiny
Datacenter ASN concentration
Hetzner, OVH, and Contabo datacenter ranges host the largest VPN exit node concentration in the EU.
Residential proxy resale
Consumer ISP ranges in Germany can appear in commercial or peer-to-peer residential proxy pools. A consumer ISP label is not proof of fraud; combine it with device, session, and routing signals.
VPN exit-node clustering
The same handful of hosting providers dominate VPN exit nodes in Germany. Maskbreak maintains live mappings of these ranges so a new IP from a known VPN ASN is flagged within seconds of going live.
Antidetect browser usage
Multi-accounting fraud against German-targeted SaaS, fintech, and e-commerce increasingly uses Kameleo, GoLogin, or AdsPower to spoof device fingerprints. Maskbreak scores these at the device layer, not the IP layer.
What Maskbreak detects for Germany traffic
- Every major VPN provider's German exit nodes (NordVPN, ExpressVPN, ProtonVPN, Mullvad, Surfshark, and 40+ more)
- Commercial or peer-to-peer residential proxy pools using consumer German IPs
- Datacenter ASNs commonly used for automation (AWS, GCP, Azure, OVH, Hetzner, DigitalOcean, Vultr, Linode)
- Tor exit nodes and known anonymous relays advertising German geolocations
- Headless browsers (Puppeteer, Playwright, Selenium) and antidetect tooling driving sessions from Germany
- Country-spoofing — when a session claims to be in Germany but the network telemetry says otherwise
VPN use & data rules in Germany
Germany enforces the GDPR through federal and state DPAs with some of Europe's strictest interpretations, plus the TTDSG for cookies and terminal-equipment access — but fraud-prevention processing under legitimate interest remains explicitly recognized. Germany has one of Europe's highest privacy-VPN adoption rates, so naive VPN blocking punishes a privacy-conscious mainstream. The stronger German signals are infrastructural: Hetzner and other German hosting providers are among the most automation-abused ASNs in the world, so datacenter-flagged "German" traffic is far more suspect than a consumer VPN exit.
