The WHOIS system originated as a method for system administrators to obtain contact information for IP address assignments or domain name administrators. The use of the data in the WHOIS system has evolved into a variety of uses, including:
  • Supporting the security and stability of the Internet by providing contact points for network operators and administrators, including ISPs, and certified computer incident response teams
  • Determining the registration status of domain names
  • Assisting law enforcement authorities in investigations for enforcing national and international laws, including, for example, countering terrorism-related criminal offenses and in supporting international cooperation procedures. In some countries, specialized non-governmental entities may be involved in this work
  • Assisting in the combating against abusive uses of Information communication technology
  • Facilitating inquiries and subsequent steps to conduct trademark clearances and to help counter intellectual property infringement, misuse and theft in accordance with applicable national laws and international treaties
  • Contributing to user confidence in the Internet as a reliable and efficient means of information and communication and as an important tool for promoting digital inclusion, e-commerce and other legitimate uses by helping users identify persons or entities responsible for content and services online
  • Assisting businesses, other organizations and users in combating fraud, complying with relevant laws and safeguarding the interests of the public.
