VPN & Proxy Detection — BelgiumDetect VPN, Proxy & Bot Traffic from Belgium
Maskbreak scores every visitor's network in real time — flagging VPN exit nodes, residential proxies, datacenter ASNs, and headless browsers originating from Belgium. Free API. Under 40ms server-side. No CAPTCHAs.
The networks Belgium traffic actually arrives from
Belgium has 293 autonomous systems on the public registry. 18 of them are hosting, cloud or transit networks holding 9.7M 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 |
|---|---|---|
| AS5432 | PROXIMUS-ISP-AS | 3.9M addresses |
| AS6848 | TELENET-AS | 2.3M addresses |
| AS47377 | ORANGE_BELGIUM_SA New company name is Orange Belgium SA | 898K addresses |
| AS2611 | BELNET | 867K addresses |
| AS31713 | GWCOMMS-MPLS A PCCW Company | 499K addresses |
| AS12392 | ASVOO VOO S.A. | 423K addresses |
| AS8368 | BENESOL-BACKBONE International Backbone | 169K addresses |
| AS9031 | EDPNET | 95K addresses |
Largest hosting-shaped networks registered in Belgium, 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 Belgium traffic needs special scrutiny
Datacenter ASN concentration
Proximus and Telenet consumer ranges are cycled through residential proxy networks to bypass EU geofencing.
Residential proxy resale
Consumer ISP ranges in Belgium 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 Belgium. 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 Belgian-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 Belgium traffic
- Every major VPN provider's Belgian exit nodes (NordVPN, ExpressVPN, ProtonVPN, Mullvad, Surfshark, and 40+ more)
- Commercial or peer-to-peer residential proxy pools using consumer Belgian IPs
- Datacenter ASNs commonly used for automation (AWS, GCP, Azure, OVH, Hetzner, DigitalOcean, Vultr, Linode)
- Tor exit nodes and known anonymous relays advertising Belgian geolocations
- Headless browsers (Puppeteer, Playwright, Selenium) and antidetect tooling driving sessions from Belgium
- Country-spoofing — when a session claims to be in Belgium but the network telemetry says otherwise
