我尝试过使用Googlesearch，但是我无法在任何地方find答案，而且这是我能想象得到的唯一地方。
如果我做whois twitter.com，那么我会得到一个非常奇怪的回应。 如果是广告，那么这是我见过的广告中最奇怪的地方。

这只是一些注册人利用的技巧，利用了whois默认包含主机和域名条目的事实。 额外的匹配来自主机（名称服务器）条目。 您可以明确要求域名条目来避免主机匹配：
$ whois domain twitter.com Whois Server Version 2.0 Domain names in the .com and .net domains can now be registered with many different competing registrars. Go to http://www.internic.net for detailed information. Domain Name: TWITTER.COM Registrar: NETWORK SOLUTIONS, LLC. Whois Server: whois.networksolutions.com Referral URL: http://www.networksolutions.com Name Server: NS1.P34.DYNECT.NET Name Server: NS2.P34.DYNECT.NET Name Server: NS3.P34.DYNECT.NET Name Server: NS4.P34.DYNECT.NET Status: clientTransferProhibited Updated Date: 10-mar-2011 Creation Date: 21-jan-2000 Expiration Date: 21-jan-2018 >>> Last update of whois database: Tue, 03 May 2011 09:47:54 UTC <<<
…等等…
编辑：顺便说一句，你也可以强制在查询结束时使用三个点（…）部分匹配。 这混淆了Linux whois客户端，因为它不能自动确定域名，所以你必须明确告诉它使用哪个whois服务器：
$ whois -h whois.verisign-grs.com "nameserver twitter.com..." Whois Server Version 2.0 Domain names in the .com and .net domains can now be registered with many different competing registrars.
