IPDetails.io gives developers and security teams one API endpoint for JSON IP intelligence across IPv4 and IPv6. Look up location, WHOIS and ASN ownership, traffic type, and abuse score, with Tor-exit, open-proxy, and VPN flags. The free core API is designed for low-latency EU/US use, while an offline database supports self-hosting. Data draws from ARIN, RIPE, APNIC, LACNIC, and AFRINIC.
I built IPDetails.io to make practical IP context easier to access from a single developer-friendly endpoint. The goal is to help teams understand network ownership, traffic classification, and risk signals without stitching together multiple services, while keeping a free core and an offline option for teams that need to self-host.
