Returns the allocated network (range, CIDR, name, handle, allocation status), the holder organisation with its postal address, and the registered abuse and technical contacts. registry names the RIR that answered — ARIN, RIPE, APNIC, LACNIC or AFRINIC. Use it for abuse reporting, network attribution and IP-block ownership checks. For risk scoring see IP Threat Intelligence; for location see IP Geolocation.
