About Whois Checker

Free Whois Checker
A WHOIS search for a domain name, such as, and reveal details about it. It may contain details such as domain ownership, registration location and date, expiration date, and nameservers allocated to the domain.

What is Whois?
Whois (pronounced "who is") is a request and response protocol that is commonly used in validating databases that store the registered users or assignees of an Internet resource, such as a domain name, an IP address block, or an autonomous system, but it is also used for a broader variety of other information. The protocol stores and transmits database content in human-readable form. The Internet Society created the current version of the WHOIS protocol.

Whois is also the name of the command-line utility used to perform WHOIS protocol requests on most UNIX systems. Furthermore, WHOIS has a relative protocol known as Referral Whois (RWhois).

Why is whois information valuable?
Whois is a popular Internet record listing that shows who owns a domain and how to contact them. Domain name registration and ownership are governed by the Internet Corporation for Assigned Names and Numbers (ICANN). Whois records have turned out to be exceptionally useful and have evolved into a necessary resource for preserving the quality of the domain name registration and website acquisition processes. 

What is contained in a Whois record?
A Whois database includes all of the contact information for the individual, group, or company who registers a domain name. The name and contact details of the Registrant (owner of the domain), the name and contact details of the Registrar (the commercial entity/organization that certified the domain name), the registration dates, the name servers, the most recent update, and the expiration date are typically included in each Whois dataset. Administrative and technical contact details may also be found in Whois data (usually, but not always, the registrant).

The two different Whois model for resource information
The thin model - the registrant, name servers, and registration dates are the only information provided by a thin Whois lookup. To obtain complete domain name ownership information, a secondary lookup at the registrar on file is required.
The thick model - Whois record contains additional information that a thin Whois record does not. Contact ( administrative, registrant,  and technical) data is commonly included in the supplementary details. The results of a lookup will reveal who owns the domain, where registered, what nameservers it uses, when registered, and its expiration date.

Given the enormous number of registrars and Whois servers available, finding Whois information takes a lot of time and work. But with the right Whois checker, you can get a spot on information, that is concise and accurate.
How accurate is a Whois data?

When a domain name is registered, the information in a Whois record is originally provided. Things change with time, and data becomes outdated. Domain registrants must be able to amend their contact information, according to ICANN. For altering the details that displays on a Whois record, each registrar has relatively different methods. It usually entails going to the registrar's website or speaking with a contact center agent to get account information. Changes to the Whois database can take a long time to take effect (typically about 24 hours). It's easier to reach a registrant or administrator when you have precise, up-to-date Whois data.

The Whois system's purpose and utility have changed throughout time in a variety of ways, and these include:

Increasing the reliability and safety of the Internet by providing suitable connections to network operators, computer incident response teams, and Internet service providers.
Domain name registration status regulation.

Providing assistance to law enforcement officers working on regional and global investigations.

Contributing to the fight against inappropriate uses of communication and information technology, such as racial discrimination, hostility, racial prejudice, xenophobia, and related intolerance, any kind of child abuse, child pornography, pedophilia, and human trafficking & exploitation.

Supporting trademark clearances and assisting in the detection of intellectual property theft, hacking, and misuse in accordance with statutory international conventions and regulatory standards.
Assisting businesses, other users, and organizations in the fight against fraud and the protection of the public interest.

Maintaining public trust and confidence in the Internet as an effective and reliable medium of communication by assisting users in determining which entities or individuals are accountable for online services and content.
Tracking down spammers or others who engage in criminal activities.

Privacy with Whois
It's vital to realize that there's no method to conceal the presence of a domain registration because anyone may look up a domain's status using Whois. The Internet Corporation for Assigned Names and Numbers (ICANN) mandates that the account information of domain name owners and managers be made accessible via Whois indexes. Mailing addresses, phone numbers, and email addresses are all included.

Private registration services (aka proxy services) are provided by some domain registrars, in which the registrar's contact information is accessible rather than the registrant's. The domain registrant and contact for this "private registration" is the organization that provides the domain privacy service. It's also worth noting that using domain privacy services isn't always an assurance of true privacy. Private information if required by law may be released by registrars.
Certain domain extensions, such as .us and .ca, have additional privacy restrictions. The National Telecommunications and Information Administration (NTIA) ruled in March '05 that all owners of .us domains will not be allowed to choose whether or not to make their data private, and that it will have to be made public. The Canadian Internet Registration Authority (CIRA) stopped publishing data about domain registrants linked with .ca domains in June '08. Corporations and organizations, on the other hand, are still compelled to make their data available to the public.

In this post, we have discussed how Whois serves as a tool of democracy on the Internet and have made plain the kind of information that is stored in the Whois database-why it is available and what to use it for. By now, you know what a Whois checker is, its uses and its importance to the public.
