What Is WHOIS and How Does It Work?

What is the Whois IP lookup? 

You can say “who is” when you see the WHOIS acronym. But it’s not an abbreviation. It’s an abbreviation for “Who owns this domain name?” 

It is a protocol for receiving replies from databases that store information about IP address owners. All databases storing domain name information may be queried with the same query protocol. 

A server’s IP is its specific location on the web. IP addresses are used the same way phone numbers are used in telecommunications networks; they direct your computer to a particular server on the internet. 

The internet’s foundation is comprised of domain names and IP addresses. Governing bodies provide IP addresses to networking organizations and keep track of those IP addresses and the entities that are given them. Whois IP lookups enable monitoring of the data for a domain.

Different types of WHOIS lookup data models 

Most individuals would be surprised to learn that WHOIS data is not kept in a central database. WHOIS records can be stored in one of two ways on WHOIS servers: 

  • WHOIS Thin Model 

This WHOIS model returns information about the registrar, the date(s) the domain was registered, and the name servers it is using as a response. 

The WHOIS server in the thin model only stores the name of another WHOIS server that contains the complete information of the registrar (as in the case of the.com TLD) and other essential information. Complete information requires a second query to the server. 

  • WHOIS Thick model

The information provided by the WHOIS model is thickened by adding registrar, technical, and administrative data.  Since a WHOIS lookup takes one query, it often returns the full contact details for the domain’s owner (thick model). 

The purpose of the WHOIS lookup

The WHOIS model’s sole purpose was to act as a directory of Internet users. With the passage of time, however, WHOIS information has become much more private, including complete contact details, making it one of the most effective data sets accessible for conducting data reconnaissance and Intel collecting operations. 

Since its inception, the WHOIS IP lookup has expanded in scope and use and is now used for a wide variety of purposes, such as: 

  • Spam and phishing attacks, as well as domain hacking, can be investigated. 
  • To receive assistance during federal investigations into sites that host offensive content, including but not limited to xenophobia, child abuse, child pornography, the illegal drug trade, hatred, violence, racial and social discrimination, etc. 
  • Supplying information to Internet service providers (ISPs), network operators (NOCs), security firms, and government law enforcement agencies to ensure the internet is as safe and open as possible. 
  • Assisting trademark authorities with inquiries into domain names that fraudulently utilize registered company names or products or engage in unauthorized brand promotion. 
  • Protecting users from becoming victims of online fraud by alerting them to phishing attempts directed at their bank accounts and other login pages for online services. 

How to use IP WHOIS Lookup to Find the Owner’s Contact Details for a Specific Address. 

You may do a WHOIS IP lookup if you need to know more about a specific IP address. To proceed, please read on. 

  • Start up your favorite IP WHOIS Lookup application. 
  • Please provide a valid IPv4 or IPv6 address in the field to use this feature. 
  • To verify the IP address, click the “CHECK NOW” button after entering it. 
  • The program does a WHOIS lookup on the supplied IP address and returns that address’s WHOIS details. 
  • Find out how to contact the IP’s owner by consulting the WHOIS data. Typically, the allocated ISP may find in the search results; moreover, if an attacker is attempting to hack you or do some other spamming behavior, this is the easiest way to contact the abuse information in the search engine’s results. 

WHOIS privacy protection

When registering a domain, you must give out personal details that should be kept secret. That is a stipulation of ICANN’s Registrar Accreditation Agreement. 

However, private registration and proxy services are available from registrars, allowing you to protect sensitive information and maintain domain privacy. 

Whois is a public database that anybody may check; however certain information is typically withheld to protect the registrant’s privacy. Personal details such as a registrant’s name, address, phone number, and country of residence generally are included. 


WHOIS is a critical component of the current internet infrastructure. WHOIS still lets us find the owners of most online domains and, more importantly, get in touch with them if we need to, even though much of the information it offers is now private. 

A WHOIS IP lookup is easy to do yourself and takes a few minutes of your time. In addition to learning how to access information, you have also gained an understanding of what WHOIS is and why it is useful.
