Whois Service

Whois service is a special network protocol designed to "read" information about a domain name. To use the service, you need to enter the domain name or IP address into the appropriate Whois line. After that, you get on the screen extended data about the domain itself in the zones ru, com and others, as well as the associated website.

The protocol is the property of ICANN, the corporation responsible for managing domain names and IP addresses. It is the key regulator in the domain industry, acting as an accrediting body for all international registrars.

There is no single centralized database in collecting and providing information about domain names. ICANN regulates this process by providing open access to information about domains of the official Whois service. This means that registrars are obliged to publish data about each registered domain, making it available to the public.

What is the Whois service for and how is it useful?

The main function of Whois domain service is the ability to quickly and for free check whether a domain is available for registration. If the information is missing in the Whois database and does not appear in the results of the occupancy check, it means that the domain is free for registration.

Whois is also popular as a source of information about the domain itself. It provides data about the domain owner, registration history and other important information: NS servers, registrar information, registration status, domain registration and expiration dates, age.

Site Check

Whois allows you to find out information about a web resource, including information about the owner of the domain and site, whether it is an organization or an individual. They are reflected in the Person, Administrator fields, although in some cases information about the owner may be hidden.
