Since the last year of the last century, private companies have been allowed to register domains, and now there are almost a thousand official domain name registrars in the world. It is possible to determine which of them registered this or that domain using a special technical protocol WHOIS (Who Is - "Who is this?").
Instructions
Step 1
Use the whois command built into the operating system if you have one of the Linux operating systems installed. It must be entered in the command line terminal and the computer must be connected to the Internet. The command syntax is very simple - for example, to get the registration data for the kakprosto.ru domain, type the following text: whois kakprosto.ru For more information on using this command, type in the command line: whois man
Step 2
Use the numerous web services that provide a wide variety of site information if you do not have access to a Linux command line terminal. It is not difficult to find them - it is enough to type whois in any search engine. The procedure itself for obtaining the necessary information is also very simple - for example, go to the page of one of these services located at https://www.reg.ru/whois and type in the only input field the name of the domain you are interested in. Then click the Check button (or press Enter) and the request will be sent to the server. The scripts will find information in the global registrar database and show you a page in which a separate section will be assigned to the domain registrar. It contains the name of the organization, its phone numbers, website address and its email address
Step 3
Not all web services of this kind provide the full amount of information, sometimes in the registrar line of search results for the domain you entered, only the registrar identifier is indicated - for example, REGHOST-REG-RIPN. You can find out which registrar is assigned this designation in the lists published by regional organizations that issue licenses for commercial activities in this area. For domains registered in RU and RF zones, such a list can be found at
