Looks up ASN and geolocation for any IPv4 or IPv6 address: ASN number, ASN org, ISP, country, region, city, postal, latitude/longitude, and timezone. Primary backend: ipapi.co (1k req/day free); fallback: ip-api.com (45 req/min free). Both are free public APIs with no auth. Use it as an IP-to-ASN, IP geolocation, IP-to-ISP lookup, WHOIS for IP, or cloud-provider attribution tool.
