Twitter.com 奇怪的 WHOIS：发生了什么事？

我尝试过用谷歌搜索这个问题，但却找不到任何答案，而这是我能想到的唯一可以找到答案的地方。

如果我 whois twitter.com，我会得到一个非常奇怪的响应。如果这是广告，那么这是我见过的最奇怪的广告地点。

有人知道这里发生了什么吗？unimundi.com 和 fatuch.com 为什么要在 twitter 的 whois 中投放广告？

答案1

这只是一些注册者利用 whois 默认包含主机和域条目这一事实而采用的伎俩。额外的匹配来自主机（名称服务器）条目。您可以明确要求提供域条目以避免主机匹配：

$ whois domain twitter.com

编辑：顺便说一句，您还可以在查询末尾使用三个点 (...) 强制进行部分匹配。这会让 Linux whois 客户端感到困惑，因为它无法自动确定域，因此您必须明确告诉它要使用哪个 whois 服务器：

$ whois -h whois.verisign-grs.com "nameserver twitter.com..."
