Internet routing and number-resource intelligence as an API, powered by RIPEstat — the open data service of the RIPE NCC, one of the world's five Regional Internet Registries. Answer the questions network engineers, security teams and researchers ask about the public internet: which Autonomous System and prefix does an IP address belong to; what is an AS (its operator/holder name, whether it is currently announced in BGP, its type and registration block); which IPv4 and IPv6 prefixes does an AS announce; who are an AS's BGP neighbours and peers (and how many); who is the abuse-reporting contact for an IP, prefix or ASN, and which RIR is authoritative; and is a prefix correctly originated according to RPKI route-origin validation (valid, invalid or unknown) with the matching ROAs. The data is real-time, drawn from the RIPE NCC's global network of BGP route collectors and the registries. Inputs accept IPv4 and IPv6 addresses, CIDR prefixes and AS numbers (with or without the AS prefix). Ideal for network operations, threat intelligence and abuse handling, BGP and RPKI monitoring, IP reputation and OSINT tooling, and internet research. Data from the RIPE NCC RIPEstat service.

Look up Autonomous System Numbers (ASNs) — the identifiers that label every network on the public internet — mapped to their owning organisation and country. 122,000+ ASNs derived from the Regional Internet Registries (ARIN, RIPE, APNIC, LACNIC, AFRINIC). Resolve an ASN to its operator (e.g. AS15169 → Google LLC, US; AS13335 → Cloudflare; AS16509 → Amazon), or search by organisation name and country (e.g. "hetzner" in DE). Ideal for network intelligence, abuse/security investigation, traffic analysis, IP-reputation tooling and BGP/peering research.
