基础问题回答

、哪些组织负责DNS，IP的管理。
、全球根服务器均由美国政府授权的ICANN统一管理，负责全球的域名根服务器、DNS和IP地址管理。全球根域名服务器：绝大多数在欧洲和北美（全球 13台，用A~M编号），中国仅拥有镜像服务器（备份）。全球一共有5个地区性注册机构：ARIN主要负责北美地区业务，RIPE主要负责欧洲地区业务，APNIC主要负责亚太地区业务，LACNIC主要负责拉丁美洲美洲业务,AfriNIC负责非洲地区业务。
、什么是3R信息。
、注册人(Registrant)、注册商(Registrar)、官方注册局(Registry)
、评价下扫描结果的准确性。
、较为准确。

使用whois域名注册信息查询

、我们可以很清楚地看到要查找的3R注册信息，包括注册人的组织和城市等信息。
、值得注意的是进行whois查询时要去掉www等前缀否则可能查询不到。
