回答（1）：

192.135.23.6 ---11000000 10000111 00010111 00000110
255.255.255.0---11111111 11111111 11111111 00000000

子网掩码是1的位对应IP地址的位是网络位，子网掩码是0的位对应IP地址的位是主机位。

网络号是网络位不变，主机位置0:
192.135.23.0 ---11000000 10000111 00010111 00000000
主机号是主机位不变，网络位置0:
0.0.0.6 ---00000000 00000000 00000000 00000110

IP地址与子网掩码就可以共同计算出网络地址范围及网络号等。
