IPLogs is a free IP intelligence API for detecting VPNs, proxies, Tor exit nodes, datacenter IPs and other anonymized traffic.
It combines multiple intelligence sources with network-level signals and active VPN protocol probing instead of relying only on static IP blacklists.
Developers can check IPv4 and IPv6 addresses, get risk and confidence results, inspect the signals behind each verdict, and perform bulk IP checks through a REST API.
No signup or API key is required.
