如何在nmap中扫描和ip范围

  • 772

我一直在使用Angry IP Scanner，有了它，我可以通过将起始 IP 和结束 IP 放在两个文本框中轻松扫描 IP 范围。现在在nmap中，我想知道如何通过提供两个 IP 来扫描 IP 范围：凝视 IP 和结束 IP。例如，我喜欢这样使用 nmap：

nmap 10.10.10.10 10.10.15.254.254

请注意，我不想在 IP 末尾使用 /24。

networking nmap ip

    从man nmap

       CIDR notation is short but not always flexible enough. For example, you
   might want to scan 192.168.0.0/16 but skip any IPs ending with .0 or
   .255 because they may be used as subnet network and broadcast
   addresses. Nmap supports this through octet range addressing. Rather
   than specify a normal IP address, you can specify a comma-separated
   list of numbers or ranges for each octet. For example,
   192.168.0-255.1-254 will skip all addresses in the range that end in .0
   or .255, and 192.168.3-5,7.1 will scan the four addresses 192.168.3.1,
   192.168.4.1, 192.168.5.1, and 192.168.7.1. Either side of a range may
   be omitted; the default values are 0 on the left and 255 on the right.
   Using - by itself is the same as 0-255, but remember to use 0- in the
   first octet so the target specification doesn't look like a
   command-line option. Ranges need not be limited to the final octets:
   the specifier 0-255.0-255.13.37 will perform an Internet-wide scan for
   all IP addresses ending in 13.37. This sort of broad sampling can be
   useful for Internet surveys and research.

    所以你需要弄清楚你的开始和结束范围是什么。从我所看到的情况来看，您似乎正在10.10.10.10通过10.10.15.254（您的结束 IP10.10.15.254.254是无效地址），但这涵盖了 6 个整个子网，每个子网以 .1 开头并以 .254 IP 结尾，所以您可能不这样做不想从 .10 开始每个子网，因为您将跳过每个子网的前 9 个 IP。所以，这样做：（我添加了一个 -(s)can 命令并搜索 (n)o-port-scan（以前的 -sP）将扫描 1,524 个 IP 地址的主机）

    nmap -sn 10.10.10-15.1-254

    但从你写的来看，这就是我认为你想要的。

    希望有帮助！
