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)。

域名状态码含义

状态含义
active / ok正常状态,无任何限制。
client transfer prohibited注册商转移锁,防止未经授权的转移。建议开启。
client update / delete prohibited额外的锁定,禁止修改或删除域名。
server hold / client hold域名未在DNS中发布,通常是因为欠费或存在争议。
redemption period已过期并被删除,但原持有者仍可付费赎回。
pending delete将在约五天内释放,届时任何人都可以注册。

常见问题

如何查询域名什么时候到期?

在上方输入域名即可;到期日期和倒计时直接来自注册局。

这个WHOIS查询工具免费吗?

免费。无需注册,正常使用不限次数。

如何查询域名是否可以注册?

请使用域名注册查询工具,它可以一次性检测一个名称在多个常用后缀下是否可注册。
