Kali linux 试用：dnsenum

dnsenum的目的是尽可能收集一个域的信息，它能够通过谷歌或者字典件猜测可能存在的域名，以及对一个网段进行反向查询。它可以查询网站的主机地址信息、域名服务器、mx record（函件交换记录），在域名服务器上执行axfr请求，通过google脚本得到扩展域名信息（google hacking），提取自域名并查询，计算C类地址并执行whois询，执行反向查询，把地址段写入文件。

从其中还是可以得到不少好玩的信息，例如：wooyun 是建立在sinaapp上的

root@kali:~/Desktop/crypt# dnsenum --enum www.wooyun.org
dnsenum.pl VERSION:1.2.
Warning: can't load Net::Whois::IP module, whois queries disabled.

信息收集方面非常有用
