This article is about how to read whois. The editor thinks it is very practical, so I share it with you. I hope you can get something after reading this article. Let's take a look at it with the editor.

Whois, pronounced as "whois" (hu yi zi) in English, is a transmission protocol used to query the IP and owner of a domain name.

Whois queries the database used to query whether the domain name has been registered and the details of the registered domain name, including the domain name owner, registrant, registration time, contact number, domain name status and so on.

When you register a domain name, you need to use the whois query to see if the domain name is registered. When you find a high-quality website, want to contact each other, exchange resources, but can not find any contact information, you can also use the domain name whois query, try to get owner information. Of course, the premise is that the domain name holder does not take strict privacy measures.

Some registrars block the whois information of international domain names. If you want to inquire, you can only contact the corresponding registrars. This protection mechanism is to prevent someone from maliciously using the contact information of this whois information to expose the customer's private information.

The working process of whois query

Whois service is an online "request / response" service. WHOIS Server monitors port 43 in the background. When an Internet user searches for a domain name (or host, contact, and other information), WHOIS Server first establishes a TCP connection with Client, then receives the information requested by the user and queries the background domain name database accordingly. If there is a corresponding record in the database, it will feed back the relevant information such as owner, management information and technical contact information to Client. When the Server output finishes, Client closes the connection, and a query process ends.

Users can conduct whois query service (https://whois.yisu.com/) on the website, which makes it more convenient to query the domain name whois on your mobile phone. When the domain name you choose has been preemptively registered, it will also provide you with certain reference options.

On the whois query results page, a comparison table of domain name information in Chinese and English is added, which explains in detail the meaning of registration information such as domain name owner, management contact, technical contact, payment contact and so on, which provides a reference for users' domain name registration.

When the domain name queried by the user has been enabled to build a website, the whois result page will also provide the user with a summary of the information and content of the website, as well as the whois query results of similar domain names, and provide users with a list of registrable domain names.

The above is how to pronounce whois. The editor believes that there are some knowledge points that we may see or use in our daily work. I hope you can learn more from this article. For more details, please follow the industry information channel.
