About this tool

This tool allows you to perform Whois lookups online. 'Whois' is the name of the protocol that is used to interrogate the servers operated by Regional Internet Registries, which hold information about every resource (IP address or domain name) registered on the Internet.

The information that you can obtain about a resource is:

  • Name of the owner company
  • Address of the owner company
  • The IP range that a certain IP belongs to
  • Contact phone number
  • Contact email
  • Administrator's name
  • Name servers


  • Whois: This is the internet resource that you want to find information about. This parameter can be an IP address or a domain name.

How it works

The tool queries the appropriate internet registrars in order to find information about the owners of the target IP address or domain.
