什么是Whois查找?
A Whois lookup is an information gathering tool that allows users to access the Whois database, which is a public directory of information about registered domain names. Specific domain extensions require domain owners to provide contact information to domain registrars based on ICANN regulations. That contact information is then displayed in our Whois lookup search results.

Whois lookup search results include:
  • Domain owner contact information.
  • Registrar information.
  • Registration date, recent renewal date, and expected expiration date.
  • 名字服务器信息。
  • Recent status of the domain name.
注意
Information displayed in the Whois lookup results will vary if the domain has Whois privacy enabled.
Whois隐私
Dynadot provides free, optional Whois privacy for all your domains. This privacy hides your domain's contact information to prevent spam and scammers from abusing this publicly available information. Dynadot believes that all domain owners are entitled to obscure their contact information from the public using privacy protection if desired, at no additional cost. You can easily set your default privacy levels for your domains through your Dynadot account.
Whois查找的运作方式
When a domain name is registered, the new domain owner is required to submit contact information, which is assigned to that registered domain for the registration period. This information is securely held by domain registrars and provided to the domain registry (who own specific top-level domains - such as .com or .net). The registry then manages the Whois lookup database for those domain extensions.

This process of collecting and holding information is defined by The Internet Corporation for Assigned Names and Numbers (ICANN), which is a non-profit organization that regulates the domain name registration process. All registries must abide by ICANN regulations to become officially accredited by the organization, with the exception of country-code top-level domains (ccTLDs) who define their own contact information tracking rules.

Whenever you use a Whois lookup, the data is pulled directly from the registry database to get the most update-to-date official information. This data is not recorded in real-time, as the database takes time to update. Recent changes may not show up in the Whois lookup search results.
What is Whois Lookup Data Used For?
Whois lookups have a wide range of uses, most commonly of which is for domain name research for acquisition purposes. This can include:
  • Researching contact information for purchasing inquiries.
  • 域名可用性检查。
  • 监控域名的过期注册机会。
除了购买或可用性查询之外,它还可以用作:
  • 新闻工具(发现谁拥有网站和内容所有权)。
  • Legal tool (contacting domain owners regarding illegal use or trademark infringement).
  • Network administration diagnosis tool (troubleshooting domain-related issues).
Whois lookups can also be used as a resource for spammers, scammers, and marketers to create contact lists. This is why domain privacy is recommended!
