The IP Intelligence API turns any IPv4 or IPv6 address into actionable intelligence with a single GET request.
It resolves reverse DNS (PTR) records, identifies the owning network through the authoritative Team Cymru IP-to-ASN dataset (ASN, AS name, BGP prefix, RIR registry, and allocation date), and flags private, reserved, and non-routable "bogon" addresses inline. Full IPv4 and IPv6 support, including compressed and IPv4-mapped IPv6 forms.
Built entirely on the Cloudflare global edge, every lookup runs over DNS-over-HTTPS with sub-second latency — no scraping, no stale databases, and no per-record licensing. It is ideal for fraud and abuse scoring, log enrichment, SIEM pipelines, allow/deny-list automation, ASN-based geo/network routing, and CDN/anycast attribution. Omit the ip parameter entirely and the API self-identifies the caller's own address.
