WHOIS

域名 Whois 查询工具，支持所有允许公开查询的 TLD 后缀的域名、IPv4/v6、ASN 的 Whois 信息查询。

Domain Whois query tool, supports domain, IPv4/v6, ASN Whois information query for all TLD suffixes that allow public queries.

info

根据 ICANN 《通用顶级域名注册数据临时政策细则（Temporary Specification for gTLD Registration Data）》和欧盟《通用数据保护条例》合规要求，在查询域名信息时，程序只返回了部分必要的信息（详见下方返回结果示例），不会返回所有者的联系方式、地址、电话、邮箱等字段。

According to the ICANN "Temporary Specification for gTLD Registration Data" and the EU "General Data Protection Regulation" compliance requirements, when querying domain information, the program only returns part of the necessary information (see the example of the return result below), and will not return the owner's contact information, address, phone, email and other fields.
