use case: VPN and proxy detection

IP geolocation for VPN and proxy detection

Use IP geolocation alongside ASN, hosting, and anonymizer signals to flag VPN, datacenter, and proxy traffic before it touches risk rules.

GET/v1/geo/{ip}

Use IP geolocation as the first layer of VPN and proxy detection when account creation, login, payment, or trial-abuse signals need a fast network classification. Geolocation alone cannot prove a VPN, but the country, ASN, hosting class, and connection type returned by providers like MaxMind and IPinfo line up with their dedicated anonymizer datasets so you can score residential vs datacenter vs hosting vs anonymizer traffic in one call. Paste a sample IP from your fraud queue, security alerts, or anti-abuse log to inspect the location and the network owner, then combine the result with behavioral signals before deciding whether to block, friction, or allow.

Statistics as of .

Use caseVPN detection
Typical AccuracyCountry accuracy is typically 99% for IPv4 in commercial databases; VPN/proxy flag precision varies by vendor.
Key Data FieldsCountry, ASN, organization, connection type, hosting flag, anonymizer/proxy flag.
Integration PointAccount signup, login risk, payment authorization, trial abuse, and free-tier rate limiting.
Sample ProviderMaxMind GeoIP2 Anonymous IP database; IPinfo Privacy Detection API.
Decision ImpactTreat hosting and anonymizer flags as friction triggers rather than auto-blocks; 1 in 4 normal users use a VPN at least monthly.

⚠ noteIP geolocation is approximate and database-driven. Combine results with behavioral, device, and account signals for high-stakes decisions; never use it as sole identity proof.

Network tool FAQ

Can IP geolocation reliably detect every VPN?

No. Geolocation can identify hosting, datacenter, and known anonymizer ASNs with high confidence, but residential proxy services rotate through real ISP IPs and can evade pure geolocation. Combine geolocation with behavioral signals and dedicated anonymizer datasets.

What signal is more reliable than country for VPN detection?

The connection type (corporate, cellular, residential, hosting) and ASN owner are stronger signals than country. A US country result on a known datacenter ASN is a much better VPN signal than the country alone.

How often should I refresh VPN-detection data?

Most commercial anonymizer databases publish updates daily or weekly. For payment or fraud workflows, refresh at least daily; for marketing analytics, weekly is usually enough.
