geolocate up to 100 IPs in one call

Working example
Parameters

Up to 100 IPv4/IPv6 addresses. A JSON array, OR a comma/space/newline-separated string. Bad/private IPs are kept (per-item status) so one bad entry never fails the call.

Preferred language for place names (country/region/city), e.g. en, de, fr, es, ru, ja. Falls back to English when a locale name is unavailable.
