我试过谷歌搜索这个,但我无法接近答案,这是我能想象到的唯一一个.
如果我做了whois twitter.com,那么我会得到一个非常奇怪的回应.如果它是广告,那么这是我见过广告最奇怪的地方.
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.

有没有人知道这里发生了什么,为什么unimundi.com和fatuch.com在twitter的whois上播放广告？
解决方法
这只是一些注册人利用whois默认包含主机和域条目这一事实的一种技巧.额外匹配来自主机(名称服务器)条目.您可以明确要求域条目以避免主机匹配：
$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,你也可以在查询结束时使用三个点(…)强制部分匹配.这会混淆linux whois客户端,因为它无法自动确定域,因此您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. Go to http://www.internic.net for detailed information. TWITTER.COM.ZEN.THE.BEST.WEBHOSTING.AT.WWW.FATUCH.COM TWITTER.COM.GET.ONE.MILLION.DOLLARS.AT.WWW.UNIMUNDI.COM To single out one record,look it up with "xxx",where xxx is one of the of the records displayed above. If the records are the same,look them up with "=xxx" to receive a full display for each record. >>> Last update of whois database: Tue,03 May 2011 10:20:07 UTC <<<
