域名 Whois:如何查找联系信息?

Jus*_*tas 2 java dns whois domain-name

我使用此代码片段获取 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、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它们吗?

通常,查找特定 .com 或 .net 域的所有者/管理员涉及执行两次 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 上查询服务器。

但是,您应该知道这是一项精简的WHOIS 服务。这意味着服务器只会向您发回有关注册商(域名注册的公司)的信息,以及到期日期、名称服务器等。

以 stackoverflow.com 为例,Verisign 告诉您注册商是 NAME.COM INC(我使用的whois是在基于 Unix 的系统上找到的程序,-h为清楚起见,指定了主机):

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

如果您想查看有关实际拥有该域的公司或个人的信息,您需要将查询发送到注册商的 WHOIS 服务器。在这种情况下,查询必须转到 whois.name.com:

$ whois -h whois.name.com stackoverflow.com
