If a host on a network has the address 172.16.45.14/30, what is the subnetwork this host belongs to?

Answer & Solution
Correct Answer: Option D
A /30, regardless of the class of address, has a 252 in the fourth octet. This means we have a block size of 4 and our subnets are 0, 4, 8, 12, 16, etc. Address 14 is obviously in the 12 subnet.

its range start from 172 16 45 10 to 172 16 45 13 bcoz we are having 2 bit under host bit so 172 16 45 14 to 172 16 45 17
so answer D is wrong
