How do you detect a VPN from an IP address?

By checking the address against the networks VPNs actually run on. Commercial VPN providers rent ranges from hosting companies, so the address resolves to a data centre rather than a residential ISP. IPScanner combines that ownership signal with routing behaviour and known-provider ranges, then returns a confidence score instead of a yes or no.

Can you tell an AI agent apart from a human visitor?

Yes, but not from the user agent. An agent can send any string it likes. Agentscan fuses the IP origin with headless-browser tells, the JA4 TLS fingerprint and a reverse-DNS verified allowlist, and returns one of four verdicts: human, known_bot, ai_agent or malicious_automation.

Is checking an IP address GDPR compliant?

An IP address is personal data under the GDPR, so you need a lawful basis. Fraud prevention and network security are recognised legitimate interests under Recital 49. IPScanner processes lookups on your behalf as a processor, and the Privacy Policy sets out what is retained.

What does IPScanner cost?

Prepaid credits cover all three products, with no subscription. Free runs your sites in monitor mode, up to 10,000 site checks a month, and geolocation, ASN and WHOIS lookups cost nothing. A site visitor check costs 1 credit and a direct lookup 10, with 25,000 free credits to start and packs from $5.

How accurate is IP geolocation?

Country level is reliable. City level is usually within 25 to 100 km and gets worse on mobile networks, where one gateway can serve a whole region. Treat city as a signal, not a fact, which is why every response carries a confidence score.
