VPN & Proxy Detection — South AfricaDetect VPN, Proxy & Bot Traffic from South Africa
Maskbreak scores every visitor's network in real time — flagging VPN exit nodes, residential proxies, datacenter ASNs, and headless browsers originating from South Africa. Free API. Under 40ms server-side. No CAPTCHAs.
The networks South Africa traffic actually arrives from
South Africa has 659 autonomous systems on the public registry. 55 of them are hosting, cloud or transit networks holding 20.9M 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 |
|---|---|---|
| AS3741 | IS | 2.6M addresses |
| AS16637 | MTNNS-AS | 2.5M addresses |
| AS29975 | VODACOM- | 1.7M addresses |
| AS37168 | CELL-C | 1.7M addresses |
| AS37457 | Telkom-Internet | 1.6M addresses |
| AS5713 | SAIX-NET | 1.5M addresses |
| AS12091 | MTNNS-1 | 1.3M addresses |
| AS2018 | TENET-1 | 1.1M addresses |
Largest hosting-shaped networks registered in South Africa, 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 South Africa traffic needs special scrutiny
Datacenter ASN concentration
Telkom SA and Vumatel ranges are increasingly resold via residential proxy services targeting fintech.
Residential proxy resale
Consumer ISP ranges in South Africa 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 South Africa. 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 South African-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 South Africa traffic
- Every major VPN provider's South African exit nodes (NordVPN, ExpressVPN, ProtonVPN, Mullvad, Surfshark, and 40+ more)
- Commercial or peer-to-peer residential proxy pools using consumer South African IPs
- Datacenter ASNs commonly used for automation (AWS, GCP, Azure, OVH, Hetzner, DigitalOcean, Vultr, Linode)
- Tor exit nodes and known anonymous relays advertising South African geolocations
- Headless browsers (Puppeteer, Playwright, Selenium) and antidetect tooling driving sessions from South Africa
- Country-spoofing — when a session claims to be in South Africa but the network telemetry says otherwise
