QUESTION NO:39
Which of the following IP hosts would be valid for PC users,assuming that a /27
network mask was used for all of the networks?(Choose all that apply.)
A.15.234.118.63
B.83.121.178.93
C.134.178.18.56
D.192.168.19.37
E.201.45.116.159
F.217.63.12.192
Answer:B,C,D
译文:在整个网络采用27位建网比特数时,下面哪个主机地址可以为PC所用?
A.15.234.118.63 B.83.121.178.93 C.134.178.18.56
D.192.168.19.37 E.201.45.116.159 F.217.63.12.192
使用255.255.255.224这个子网掩码.这个网络就被划分为块为32大小的子网络.我们以32大小的块.成倍增加.依次是32,64,96,
128,160,192,224,则一目了然.

共32为嘛27为掩码就是224,这个掩码每个段呢就最多32个地址,但是除去网络地址1和广播地址31之后 就省30个了,就是1-31、34-62是可以用的 以此类推.
