NS简介

访问某网站的时候,我们只需要打开浏览器输入例如:就可以解析到该网站.为了便于记住不需要输入长长的IP地址去访问,这时DNS把相对应的域名解析成IP地址,这就是DNS域名解析.

关于域名

域名的层次划分用点来分割,最低在左边,高的在右边.例如:.域名服务是基于UDP实现端口号为53.子域名还划分国家,地区,组织.

域名还需要由遍及世界的域名服务器去解析,也进行划分高低层次,由高到低:根域名服务器,顶级域名服务器,权限域名服务器,本地域名服务器.实际上DNS系统是一种分布式地址信息数据库系统.

查询过程:主机先向本地域名服务器进行递归查询->本地域名服务器迭代查询,向根域名服务器查询->根域名服务器告诉本地域名服务器,下次该查询的顶级域名服务器dns.com的IP地址->本地域名服务器向顶级域名服务器dns.com进行查询->顶级域名服务器com告诉本地域名服务器,下一步查询权限服务器dns.baidu.com的IP地址->本地域名服务器向权限服务器dns.baidu.com进行查询->权限服务器dns.baidu.com告诉本地域名服务器所查询的主机的IP地址->本地域名服务器最后把查询结果告诉主机.

DNS侦查

DNS侦查关心的是:识别谁拥有一个特定域或一系列IP地址,定义实际域名的DNS信息和标识目标的IP地址以及目标之间的路由.

whois查询

whois是识别分配给网站的地址,相关信息数据包括注册用户的域名或IP地址等等.

Recon-ng

这个开源框架比较强大,模块使用python编写,可自行建立改变模块也可利用第三方的API可能会被第三方跟踪.在kali中集成会把收集的数据放入数据库中. 有很多模块水土不服.

第一次启动会告知你没有安装的依赖
