VPN & Proxy Detection — TurkeyDetect VPN, Proxy & Bot Traffic from Turkey
Maskbreak scores every visitor's network in real time — flagging VPN exit nodes, residential proxies, datacenter ASNs, and headless browsers originating from Turkey. Free API. Under 40ms server-side. No CAPTCHAs.
The networks Turkey traffic actually arrives from
Turkey has 877 autonomous systems on the public registry. 78 of them are hosting, cloud or transit networks holding 14.3M 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 |
|---|---|---|
| AS9121 | TTNET | 6.8M addresses |
| AS16135 | TURKCELL-AS Turkcell A.S. | 1.7M addresses |
| AS34984 | TELLCOM-AS | 1.5M addresses |
| AS20978 | TT_MOBIL Istanbul | 804K addresses |
| AS15897 | VODAFONETURKEY | 745K addresses |
| AS8386 | KOCNET | 464K addresses |
| AS47524 | AS-TURKSAT | 453K addresses |

Largest hosting-shaped networks registered in Turkey, 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 Turkey traffic needs special scrutiny
Datacenter ASN concentration
Türk Telekom and Turkcell consumer ranges fuel a significant share of bypass-driven VPN traffic into the EU.
Residential proxy resale
Consumer ISP ranges in Turkey 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 Turkey. 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 Turkish-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 Turkey traffic
- Every major VPN provider's Turkish exit nodes (NordVPN, ExpressVPN, ProtonVPN, Mullvad, Surfshark, and 40+ more)
- Commercial or peer-to-peer residential proxy pools using consumer Turkish IPs
- Datacenter ASNs commonly used for automation (AWS, GCP, Azure, OVH, Hetzner, DigitalOcean, Vultr, Linode)
- Tor exit nodes and known anonymous relays advertising Turkish geolocations
- Headless browsers (Puppeteer, Playwright, Selenium) and antidetect tooling driving sessions from Turkey
- Country-spoofing — when a session claims to be in Turkey but the network telemetry says otherwise
VPN use & data rules in Turkey
Turkey's KVKK (Law No. 6698) governs personal data, with controllers registering under VERBIS; fraud-prevention processing fits its legitimate-interest provisions much like the GDPR. The practical nuance for risk teams: Turkey has some of the highest consumer VPN adoption in the world, because residents routinely use VPNs to reach throttled or restricted platforms. A VPN flag from Turkish traffic is therefore a weak fraud signal by itself — hard-blocking VPNs there will reject large numbers of legitimate customers. The pattern that works: treat VPN-only sessions from Turkey as review rather than block, and reserve hard blocks for sessions where device-layer evidence (antidetect tooling, automation, emulators) stacks on top of the network signal.
