源主机的IP地址为10.192.240.10，目的地为10.192.250.10。这两个主机是否驻留在同一网络上？ 如果是这样，我们怎样才能找到它。
答案 0 :(得分：3)
首先要知道的是网络掩码。如果不同的位在网络掩码的零范围内，则它们应该在同一网络上路由。例如，我的家庭网络使用192.168.0.0/255.255.254.0，这意味着192.168.0.0-192.168.1.255由我的家庭路由器路由... 192.168.1.10与192.168.0.10在同一网络上。
您还可以尝试从一个到另一个进行traceroute以确定跳数。一跳意味着主机之间没有活动路由，因此很可能是同一网络。
一跳，同一网络（有点......桌面是有线连接，远程是无线连接;但从IP的角度来看，相同）：
