Find out the data of the owner of a site or domain, what is WHOIS - decryption of service values

Sometimes you may need to find out who owns the site or the domain on which it is located. This information may differ because the domain can be registered for one person or company, but in fact another person can use the site.

To find out the data of the domain owner , you can first go to this domain address and look for information on the site that opens. But this method is not always effective, so you should use special services that will show information about the domain owner. These services are called WHOIS, which literally means "who it is."


What is WHOIS ? WHOIS is often understood as a site that displays information about a domain. But in fact, WHOIS is an application layer network protocol based on the TCP protocol, the main use of which is to obtain registration data about the owners of domain names, IP addresses and autonomous systems from public databases. Initially, WHOIS was used only by administrators from the console, but today, for the convenience of ordinary users, various sites provide access to WHOIS in a clear interface.

However, for some domain zones or in some situations, information in WHOIS may be hidden or replaced with registrar data. This is especially true for domains in the zone .ru and .рф - according to the law on personal data of the Russian Federation, registrars are obliged to hide the owner's data. For domains in the .com zone, the hide data from the registrar service may be used, the domain owner will have to pay for it, or in some cases it may be provided free of charge for a certain period. In such cases, you should contact the specified data of the registrar to contact the owner of the domain.

Today there are many WHOIS services, sometimes it is not clear which WHOIS service to use . In addition, some services provide incomplete information. Usually, the first service from the search results is used, but this does not guarantee a good result. Examples of WHOIS services:
