第3题：

The 201.145.32.0 network is subnetted using a /26 mask. How many networks and IP hosts per network exists using this subnet mask?

A．4 networks and 64 hosts

B．64 networks and 4 hosts

C．4 networks and 62 hosts

D．62 networks and 2 hosts

E．6 network and 30 hosts


正确答案：C
解析：Explanation:
A class C network with a 26 bit mask requires 2 bits for the network address, leaving 6 bits for host addresses. Using the 2n-2 formula (22 for the network and 26-2for hosts) we have 4 network addresses and 62 host addresses.

Incorrect Answers:
A, B: This is not a possible combination. No network mask will provide for 64 usable hosts, because we must always subtract 2 for the network and broadcast address.
D. This would be the result of a /30 mask.
E. This would be the result of a /27 network mask.
