nmap -vv scanme.nmap.org 扫描的范围

根据提供的引用内容，nmap在扫描时默认会使用ping扫描，只有主机存活，Nmap才会继续扫描。而在使用CIDR风格的地址时，可以附加一个/<numbit>在一个IP地址或主机名后面，Nmap将会扫描所有和该参考IP地址具有<numbit>相同比特的所有IP地址或主机。因此，nmap -vv scanme.nmap.org扫描的范围应该是scanme.nmap.org这个主机。

nmap -v scanme.nmap.org 扫描与 nmap -vv scanme.nmap.org 扫描的区别是什么

根据提供的引用[1]，nmap是一款网络探测和安全审计工具。使用-v选项可以增加扫描的详细程度，使用-vv选项可以进一步增加详细程度。因此，nmap -v scanme.nmap.org扫描的详细程度比nmap -vv scanme.nmap.org扫描的详细程度要少。

下面是两个命令的示例：

1. nmap -v scanme.nmap.org扫描的输出示例：

nmap -v scanme.nmap.org 扫描与 nmap -vv scanme.nmap.org 扫描的区别是什么?

根据提供的引用[1]，nmap是一款网络探测和安全审核工具。它可以用来扫描网络主机，确定哪些主机在运行，哪些服务在运行以及哪些防火墙在运行。nmap还可以确定主机的操作系统和应用程序版本等信息。

根据提供的引用，nmap的-v选项可以增加扫描的详细程度，而-vv选项则可以进一步增加详细程度。因此，nmap -v scanme.nmap.org扫描的详细程度比nmap -vv scanme.nmap.org扫描的详细程度要低。
