Resolve a public IP address, or a domain, to the autonomous system that announces it: AS number and name, the announced prefix, country code, registry and allocation date. Answers who operates the network an address sits on, which tells a hosting provider from a CDN from a corporate network. It does not identify the site owner, and private or reserved addresses have no announcing AS. ip_geolocation returns the same AS data plus country and PTR. Anonymous and rate-limited per IP.
