VPN & Proxy Detection — MexicoDetect VPN, Proxy & Bot Traffic from Mexico
Maskbreak scores every visitor's network in real time — flagging VPN exit nodes, residential proxies, datacenter ASNs, and headless browsers originating from Mexico. Free API. Under 40ms server-side. No CAPTCHAs.
The networks Mexico traffic actually arrives from
Mexico has 531 autonomous systems on the public registry. 43 of them are hosting, cloud or transit networks holding 21.4M 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 |
|---|---|---|
| AS8151 | UNINET | 13.4M addresses |
| AS13999 | Mega Cable, S.A. de C.V. | 2M addresses |
| AS6503 | Axtel, S.A.B. de C.V. | 1.3M addresses |
| AS11172 | Alestra, S. de R.L. de C.V. | 598K addresses |
| AS13591 | Mexico Red de Telecomunicaciones, S. de R.L. de C.V. | 493K addresses |
| AS11888 | Television Internacional, S.A. de C.V. | 461K addresses |
| AS28509 | Cablemas Telecomunicaciones SA de CV | 291K addresses |
| AS22884 | TOTAL PLAY TELECOMUNICACIONES SA DE CV | 285K addresses |
Largest hosting-shaped networks registered in Mexico, 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 Mexico traffic needs special scrutiny
Datacenter ASN concentration
Telmex consumer IPs are heavily abused in residential proxy networks targeting US-facing SaaS platforms.
Residential proxy resale
Consumer ISP ranges in Mexico 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 Mexico. 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 Mexican-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 Mexico traffic
- Every major VPN provider's Mexican exit nodes (NordVPN, ExpressVPN, ProtonVPN, Mullvad, Surfshark, and 40+ more)
- Commercial or peer-to-peer residential proxy pools using consumer Mexican IPs
- Datacenter ASNs commonly used for automation (AWS, GCP, Azure, OVH, Hetzner, DigitalOcean, Vultr, Linode)
- Tor exit nodes and known anonymous relays advertising Mexican geolocations
- Headless browsers (Puppeteer, Playwright, Selenium) and antidetect tooling driving sessions from Mexico
- Country-spoofing — when a session claims to be in Mexico but the network telemetry says otherwise
