我映射到一个 IP 地址，以获取我拥有什么样的网络和互联网连接。我认为我映射的 ip (192.168.1.252) 应该是本地的，但似乎不是。我仍在努力了解这里发生了什么，所以我希望你能帮助我。

好吧，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：

“本地”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。

这是对网络掩码的一个很好的解释。

这是在安全网络上而不是您的家庭网络上，对吗？如果是这样，那么您将获得的是您的机器信息而不是网络信息。由于您是服务器系统上网络的一部分，因此远程登录该服务器并尝试相同的操作。
