在题库碰到一个问题，在考试的时候不知道按哪种方法解答。在考试划分子网的题目里，不知道要不要把网关算在主机个数里面，还是另外算呢。望各位仁兄指点，谢谢！！
所碰到具体题目如下：
选择题434:
You are working in a data center environment and are assigned the address range 10.188.31.0/23.You are
asked to develop an IP addressing plan to allow the maximum number of subnets with as many as 30 hosts
each.Which IP address range meets these requirements?
答案选:B(10.188.31.0/26)
解答：30台主机还需要一个网关，所以需要31个有效IP地址
