how to search domain information

There are several methods to search domain information, which are introduced as follows:

Whois Query

• Official Whois Databases: Many domain registrars and organizations maintain Whois databases. For example, ICANN (The Internet Corporation for Assigned Names and Numbers) has a comprehensive Whois database. You can access its official website and enter the domain name you want to query in the search box to obtain detailed information such as the domain registrant, registration date, expiration date, and DNS records.
• Domain Registrar’s Whois Tool: Each domain registrar usually provides a Whois query tool on its website. If you know the registrar of a specific domain, you can go to the registrar’s website, find the Whois search option, and enter the domain name to get relevant information. For example, GoDaddy offers a Whois search service where you can enter the domain name and retrieve details like the owner, administrator, and contact information.
• Third-party Whois Lookup Tools: There are also many third-party websites that provide Whois lookup services, such as Who.is and Whois.com. These platforms can query the Whois information of various domains and present the results in an easy-to-understand format.

Domain Registration Agency’s Website Query

Most domain registration agencies offer domain query services on their official websites. You can directly go to the website of a well-known domain registration agency, click on the “Domain Registration Query” or similar option, enter the domain name you want to check, select the appropriate domain suffix if needed, and then click the query button. The query results usually include information such as the domain registrant, the registration service agency where the domain is located, the contact email of the registrant, the domain registration date, and the expiration date.

CNNIC Query (for Chinese Domains)

In China, you can use the Whois query service provided by CNNIC (China Internet Network Information Center). Log in to the CNNIC official website, enter the Whois query page, and input the domain name you want to query. You can obtain detailed information such as the domain registration information, trademark registration information, and DNS information of Chinese domains1.

Reverse Domain Name Resolution

Some reverse domain name resolution tools allow you to query domain information by entering an IP address. This is useful when you know the IP address of a website and want to find out the corresponding domain name. By using such tools, you can get the domain name associated with the given IP address, which helps in understanding the website’s identity and other related information1.
