VPN & Proxy Detection — FranceDetect VPN, Proxy & Bot Traffic from France
Maskbreak scores every visitor's network in real time — flagging VPN exit nodes, residential proxies, datacenter ASNs, and headless browsers originating from France. Free API. Under 40ms server-side. No CAPTCHAs.
The networks France traffic actually arrives from
France has 1,488 autonomous systems on the public registry. 106 of them are hosting, cloud or transit networks holding 66.1M 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 |
|---|---|---|
| AS3215 | France Telecom - Orange | 20M addresses |
| AS15557 | LDCOMNET --- I3Dnet --- | 15.8M addresses |
| AS12322 | PROXAD | 8.8M addresses |
| AS5410 | BOUYGTEL-ISP | 7.1M addresses |
| AS16276 | OVH | 4.6M addresses |
| AS2200 | FR-RENATER Reseau National de telecommunications pour la Technologie | 2.5M addresses |
| AS51207 | FREEM | 1.3M addresses |
| AS29447 | TIF-AS Iliad Italia S.p.A | 983K addresses |
Largest hosting-shaped networks registered in France, 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 France traffic needs special scrutiny
Datacenter ASN concentration
OVH-hosted residential proxy services account for a disproportionate share of fraudulent traffic into French SaaS platforms.
Residential proxy resale
Consumer ISP ranges in France 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 France. 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 French-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 France traffic
- Every major VPN provider's French exit nodes (NordVPN, ExpressVPN, ProtonVPN, Mullvad, Surfshark, and 40+ more)
- Commercial or peer-to-peer residential proxy pools using consumer French IPs
- Datacenter ASNs commonly used for automation (AWS, GCP, Azure, OVH, Hetzner, DigitalOcean, Vultr, Linode)
- Tor exit nodes and known anonymous relays advertising French geolocations
- Headless browsers (Puppeteer, Playwright, Selenium) and antidetect tooling driving sessions from France
- Country-spoofing — when a session claims to be in France but the network telemetry says otherwise
VPN use & data rules in France
France applies the GDPR under one of Europe's most active regulators, the CNIL, which has repeatedly affirmed fraud prevention as a legitimate interest (GDPR Recital 47) — network and device risk scoring of French visitors is lawful without a consent wall when proportionate. France is also a mature consumer-VPN market: privacy-motivated VPN use is mainstream, so a VPN flag alone shouldn't end a French customer's session. What should get attention is the combination Maskbreak is built to catch: French-geolocated residential proxy exits driving signup bursts, or datacenter ASNs (OVH is French infrastructure, heavily used for automation worldwide) presenting as consumer traffic.
