问如何在nmap中扫描ip范围

EN

来自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。据我所见，您正在通过10.10.10.10通过10.10.15.254 (您的终结IP的10.10.15.254.254是一个无效的地址)进行操作，但这涵盖了6个整个子网，每个子网以一个.1开始，以一个.254 IP结束，因此您可能不想在.10上启动每个子网，因为您将跳过每个子网的前9个IP。所以，这样做吧：(我添加了a-(S)可以命令和搜索(N)o端口扫描(前称-sP)将扫描1,524个IP地址的主机)。

nmap -sn 10.10.10-15.1-254

但根据你写的，这就是我认为你想要的。

希望这能帮上忙！
