VPN & Proxy Detection — IrelandDetect VPN, Proxy & Bot Traffic from Ireland
Maskbreak scores every visitor's network in real time — flagging VPN exit nodes, residential proxies, datacenter ASNs, and headless browsers originating from Ireland. Free API. Under 40ms server-side. No CAPTCHAs.
The networks Ireland traffic actually arrives from
Ireland has 208 autonomous systems on the public registry. 14 of them are hosting, cloud or transit networks holding 4.8M 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 |
|---|---|---|
| AS1213 | HEANET | 1.8M addresses |
| AS5466 | EIRCOM Internet House | 1.1M addresses |
| AS15502 | VODAFONE-IRELAND-ASN | 502K addresses |
| AS43515 | YOUTUBE YOUTUBE | 451K addresses |
| AS2110 | AS-BTIRE BT Ireland was previously known as Esat Net, EUnet Ireland & IEUnet. | 243K addresses |
| AS31122 | DIGIWEB-AS | 199K addresses |
| AS13280 | H3G | 155K addresses |
| AS34245 | MAGNET-AS | 105K addresses |
Largest hosting-shaped networks registered in Ireland, 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 Ireland traffic needs special scrutiny
Datacenter ASN concentration
AWS Dublin and Microsoft Azure Dublin are the largest datacenter VPN exit sources in Western Europe.
Residential proxy resale
Consumer ISP ranges in Ireland 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 Ireland. 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 Irish-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 Ireland traffic
- Every major VPN provider's Irish exit nodes (NordVPN, ExpressVPN, ProtonVPN, Mullvad, Surfshark, and 40+ more)
- Commercial or peer-to-peer residential proxy pools using consumer Irish IPs
- Datacenter ASNs commonly used for automation (AWS, GCP, Azure, OVH, Hetzner, DigitalOcean, Vultr, Linode)
- Tor exit nodes and known anonymous relays advertising Irish geolocations
- Headless browsers (Puppeteer, Playwright, Selenium) and antidetect tooling driving sessions from Ireland
- Country-spoofing — when a session claims to be in Ireland but the network telemetry says otherwise
