Question

我已经映射到一个IP地址，以便获得我所拥有的网络和互联网连接。我认为ip i nmapped（192.168.1.252）应该是本地的，但它似乎不是。我仍然想要了解这里发生的事情，所以我希望你能帮助我。

我确定我没有使用代理。我的连接信息日志在这里：

          inet addr:192.168.254.237  Bcast:192.168.254.255  Mask:255.255.255.0

我的nmap命令和日志在这里：

Answer 1

“Local”由接口IP地址和网络掩码的组合定义。使用24位网络掩码，192.168.1.0和192.168.254.0绝对是不同的网络。

Here is a good explanation of netmasks

Answer 2

这是在安全的网络而不是您的家庭网络吗？如果是这样，那么你将得到的是你的机器信息而不是网络信息。由于您是Server系统上的网络的一部分，因此远程登录到该服务器并尝试相同的操作。

192.168.1.252似乎是本地IP，但它不是本地的？
