Try:

Named Services

Where we can attribute, the response includes the VPN service name (e.g. NordVPN, Mullvad, ProtonVPN) and the percentage of recent days the IP behaved as an anonymizer.

Tor & Relays

Live Tor exit-node list plus Apple Private Relay, iCloud Relay, and other relay protocols — flagged separately so you can treat them differently from raw VPNs.

Residential Proxies

The hardest category to spot. Lookip combines passive measurements and direct proxy-config captures to flag residential-proxy IPs operators sell as “clean.”

FAQ

Does this work for IPv6?
Yes — both address families share the same endpoint and response shape.
How fresh is the VPN list?
Threat signals refresh continuously from our enrichment pipeline.
How many lookups do I get?
50 per visitor IP per UTC day for guests. Create a free account for +100 — your existing usage carries over.
