SmartWhois is a useful network information utility that allows you to find all the available information about an IP address, hostname, or domain, including country, state or province, city, name of the network provider, administrator and technical support contact information.

Unlike standard Whois utilities, SmartWhois can find the information about a computer located in any part of the world, delivering all the related records within a few seconds. Even if an IP address cannot be resolved to a hostname, it's not a problem for SmartWhois.
