IP geolocation lookup (geoip / IP location API) — geolocate any IPv4 or IPv6 address to city, region, country, latitude/longitude, timezone, and ISP/ASN as structured JSON so agents can localize content and enrich user records without a paid geolocation subscription. For proxy/VPN/anonymizer or hosting/datacenter detection, use /ip-risk/score or /ip-reputation/analyze.
