大家好，我是BaCde。公众号开通了2个月，一直没发内容。本来计划写写网站建设思路，今天先写一篇网站的使用分享。

网站自发布以来，一直没有什么说明和教程。因为它的功能非常单一，不需要做太多介绍。但是呢，有一些小细节和场景，我觉得可以分享下。

首先，网站基础功能可以查询网站子域名，根据IP地址或IP段查询绑定的域名信息，这里支持IPv6的地址和地址段。目前最大支持显示1万条（大多数情况下足够了）。其中查询结果页面中有导出csv的功能，可以导出全部结果。其实不导出，查询全部结果只需要加入参数?full=1即可。目前大多数开源工具采集时采用也是这样的方式。

下面来说下实际应用场景。

信息收集

在收集ASN信息时，可以根据反向IP段查询，迅速确定筛选出目标的资产。

比如下图中搜索到的腾讯结果中，有很多ip段时属于腾讯云服务的机器，这些IP对我们挖掘漏洞来说，意义不大。但是可能又会存在夹杂在其中的个别目标。这时候就可以使用Reverse IP功能进行查询，然后筛选出目标或者筛选IP段。

下面随便挑了一个（58.87.64.0/18）查询结果来展示下，发现大多数不是腾讯的域名，则可以跳过，或者从中筛选出腾讯的。

溯源定位

这里主要说两个场景，第一个就是扫到某个IP存在漏洞，想知道哪个厂商的，第二个就是对于攻击IP地址是属于哪个机构的。这是两个非常常见的需求。

这里一种方法是直接查询IP地址，那么，当ip地址查不到时怎么办呢？

今天就在微信群里遇到一个例子。有人在日志中发现了360某团队的一个dnslog的地址，但是打开其域名时一个空白地址。这里我通过获取到解析的IP地址，查询C段，然后很快速的发现了dnslog平台的登录地址，根据版权信息确认是360的。

其发现的地址形如：xxx.b.nslog.0kee.360.cn。访问nslog.0kee.360.cn为空白，其解析的IP地址为123.59.211.124。通过RapidDNS来查询C段，查询链接：https://rapiddns.io/sameip/123.59.211.124/24#result。

在结果中可以发现一个0kdns.net的域名，访问后就是dnslog平台登录地址。

好了，以上就是我经常使用到的方法，跟大家分享出来。另外，网站由于网络原因，可能会不太稳定。有问题大家可即时反馈，看到后我会第一时间来解决。
