可以分配给前缀为 192.168.56.128/26 的 class c 子网的最后一个 IP 地址是什么？
What is the last IP address that can be assigned to a class c subnet with a prefix of 192.168.56.128/26?

您是如何得到这个答案的（以便我以后可以自己解决？）
谢谢！
26-bit mask means 32 bits (address length) - 26 bits (mask length) = 6 address bits
2^6 = 64 addresses (0..63)
192.168.56.128 + 0 = 192.168.56.128 subnet
192.168.56.128 + 1 = 192.168.56.129 first address
.

192.168.56.128 + 62 = 192.168.56.190 last address
192.168.56.128 + 63 = 192.168.56.191 broadcast address
