Notes
- SmartWhois v2.0 uses WhoIs service query recursively (for example, first whois.arin.net, then whois.ripe.net and so on, if necessary).
- Every public IP address or IP address block in the Internet is registered to an owner.
- Private IP addresses (as defined by RFC 1918) does not have an owner.
- IP address owner is queried using five Regional Internet registries.
