Can you please help me with the following question
How many subnets can be gained by subnetting 172.17.32.0/23 into a /27 mask, and how many usable host addresses will there be per subnet
A. 8 subnets 31 hosts
B. 8 subnets, 32 hosts
c. 16 subnets 30 hosts
D. 16 subnets 32 hosts
E. A class B address cant be subnetted into the fourth octet
Any idea how can i solve this problem ?

I believe the correct answer is C
172.17.32.0 /27 provides 8 subnets and 30 hosts right ?
The /23 mask provides 128 subnets and 510 hosts right ?
the 27 mask will give me the differnce 27-24=4 subnet bits i.e 16 subnets -

Correct, and your answer C is sound as well.the 27 mask will give me the differnce 27-23=4 subnet bits i.e 16 subnets
