无论何时使用WHOIS命令,都不会返回任何有用的信息.我通常必须去Godaddy,Dnsstuff或其他服务来获取数据.我理解其原因主要是垃圾邮件.
我只是想知道其他服务如何获得这些数据.他们使用不同类型的WHOIS命令吗？还混淆了一些来自WHOIS命令的数据生成数据只是垃圾邮件.做whois google.com的示例生成垃圾网站,例如GOOGLE.COM.ZZZZZZ.THE.BEST.WEBHOSTING.AT.WWW.FATUCH.COM.这些数据来自哪里？

解决方法
假设您正在使用debian / ubuntu whois库,那么您的问题的简短答案就是使用
$whois -h whois.crsnic.net "domain google.com"
这是一个很长的答案.
.COM TLD是Thin WHOIS.当您执行WHOIS查询时,WHOIS工具首先向Verisign(主机名whois.crsnic.net)发送WHOIS查询,并从响应中提取引用.
默认情况下,当您从域example.com查询Verisign时,Whois会在几个不同的对象(包括域名,注册商名称和名称服务器)中对字符串“example.com”进行非常广泛的搜索.
您可以通过指定关键字来优化查询,如Verisign文档中所述.
http://registrar.verisign-grs.com/whois/iframe/help.html?ppath=www.verisigninc.com/products-and-services/domain-name-services/whois&
上面的命令正是我所解释的.它不是google.com,而是向Verisign发送完整的查询“domain google.com”.您必须显式传递-h标志,因为Whois会尝试猜测要从查询中查询的主机名,但它会失败,因为它无法将查询“domain google.com”识别为有效域.
这是命令的结果.
