IPDetails.io gives developers and security teams one API endpoint for JSON intelligence on IPv4 and IPv6: location, WHOIS and ASN ownership, hosting/residential/business classification, and abuse risk signals. Typical response times are around 10ms in the EU and US. The free core API is complemented by an offline database for self-hosting, with detection for Tor exits, open proxies, and VPNs. Data is grounded in RIR records from ARIN, RIPE, APNIC, LACNIC, and AFRINIC.
