• WHOIS（读作“Whois”，而非缩写）是用来查询互联网中域名的IP以及所有者等信息的传输协议。简单来说，WHOIS就是一个用来查询已经被注册域名的详细信息的数据库，包括域名注册人（或单位）、域名注册商、域名注册时间、域名到期时间、域名注册人联系方式等。
• 早期的WHOIS查询多以命令列接口（Command Line）存在，但是现在出现了一些基于网页接口的简化线上查询工具，甚至可以一次向不同的数据库查询。
• 网页接口的查询工具仍然依赖WHOIS协议向服务器发送查询请求，命令列接口的工具仍然被系统管理员广泛使用。
• WHOIS通常使用TCP协议43端口。每个域名或IP的WHOIS信息由对应的管理机构保存，例如，以.com结尾的域名的WHOIS信息由.com域名运营商VeriSign管理，中国国家顶级域名.cn域名由CNNIC管理。
• 通常情况下，域名或IP的信息可以由公众自由查询获得，具体的查询方法是登陆由管理机构提供的WHOIS服务器，输入待查询的域名进行查询。

• WHOIS服务是一个在线的“请求/响应”式服务。
• WHOIS Server运行在后台监听43端口，当Internet用户搜索一个域名（或主机、联系人等其他信息）时，WHOIS Server首先建立一个与Client的TCP连接，然后接收用户请求的信息并据此查询后台域名数据库。
• 如果数据库中存在相应的记录，它会将相关信息如所有者、管理信息以及技术联络信息等，反馈给Client。
• 待Server输出结束，Client关闭连接，至此，一个查询过程结束。

• 如果域名持有者要注册Whois服务，必须要提供准确的信息。如果你的域名是出于个人使用目的，那么必须要提供家庭住址、电话号码和电子邮件地址等信息。
• 如果你拥有一个域名，那么你的隐私可能因为Whois当前的隐私策略而被没有必要地泄露出去，但人们对此还是束手无策。
• 有些注册商，对国际域名的whois信息是屏蔽的，如果要查询只能联系对应的注册商。这种保护机制是防止有人恶意利用这种whois信息的联系方式，暴露客户的隐私信息。客户的隐私信息。
