域名 Whois:如何查找联系信息?

Domain name Whois: how to find contact information?

我将此代码片段用于 Whois 信息:

org.apache.commons.net.whois.WhoisClient whois = new org.apache.commons.net.whois.WhoisClient();
whois.connect("whois.verisign-grs.com", 43);

String domainWhois = whois.query(domainName);

whois.disconnect();

我获得了创建日期、到期日期、注册商和名称服务器,但没有与管理或技术联系人相关的数据。有什么办法可以得到吗?

通常,查找特定 .com 或 .net 域的 owner/administrator 涉及执行两次 WHOIS 查找。

Verisign 是这些顶级域的注册机构。您问题中的代码是正确的,因为您必须在 whois.verisign-grs.com 查询服务器。

但是,您应该知道这是一项 thin WHOIS 服务。这意味着服务器只会向您发回有关 注册商 (注册域名的公司)以及到期日、名称服务器等的信息。

以 whosebug.com 为例,Verisign 告诉您注册商是 NAME.COM INC(我使用的是基于 Unix 的系统上的 whois 程序,指定主机 -h 为清楚起见):

$ whois -h whois.verisign-grs.com whosebug.com
