注意了：(IP network contains a range of 2n IP addresses where 0 <= n <= 32)改成（IP network contains a range of 2^n IP addresses where 0 <= n <= 32）下面在谈谈个水题其实学了网络的同学写这道题应该很简单的！~IP地址太熟悉了，这么小题一下AC。不过我还wa一次！不小心啊！ 这里还是有点问题，总认为网络掩码不可能是：255.255.255.255，最最长也是255.255.255.254 啊！当只有一个IP地址时，应该是255.255.255.254。这里却把255.255.255.255当成了最后的答案！ 无聊的简单网络知识题！ Followed by: Post your reply here: |
