求解题目：What IP address should be assigned to PC1?


求解题目：What IP address should be assigned to PC1?
192.168.1.158是网络段地址,首个可用IP地址是192.168.1.159,选D
再问： 答案给的是C，我自己算的是C和D。 请问你有没有关于这种题目的详解的地址？
再答： 我理解错题意了，原来那个192.168.1.158/28是路由器的IP而非网络段地址，那此题确实应该选C 把IP和掩码都转成二进制形式来看，每一位对齐 192.168.1.158=11000000.10101000.00000001.10011110 掩码28=11111111.11111111.11111111.11110000 掩码为1的位不可变，掩码为0的位可以变，所以该可变的就是最后那个数字，从10011000-10011111，也就是144-160，第一个数字144为网络段地址，最后一个数字160为该网段广播地址，不可用作IP地址，故该网段的可用地址为192.168.1.145-192.168.1.159，首个可用IP地址为192.168.1.145
