什么是WHOIS查询?

WHOIS是记录域名或IP地址段持有者信息的公开目录。通过WHOIS域名查询,您可以看到域名的注册商、注册时间和到期时间、域名服务器、状态码,以及用于举报垃圾邮件或钓鱼网站的滥用投诉联系方式。对于IP地址,则会显示网络的所有者、地址范围,以及分配该地址的区域互联网注册管理机构(ARIN、RIPE NCC、APNIC、LACNIC或AFRINIC)。

RDAP:新一代WHOIS

本工具使用注册数据访问协议(RDAP)进行查询,它是旧式纯文本WHOIS协议的结构化JSON替代方案。我们会根据IANA的引导文件,为每个顶级域名或IP地址段找到对应的权威注册局服务器,因此查询结果直接来自源头。对于少数尚未提供RDAP的国家和地区顶级域名,我们会改用传统的43端口WHOIS查询。

为什么所有者姓名被隐藏了?

自欧盟《通用数据保护条例》(GDPR)于2018年5月生效以来,注册商默认会隐去个人注册人的个人信息,许多注册商还为企业提供同样效果的免费隐私保护服务。如需联系域名所有者,请使用注册商的联系表单或页面上显示的滥用投诉地址。进一步了解WHOIS与隐私保护(英文)。
