Q. 134
Given an IP address of 172.16.2.160 and a subnet mask of 255.255.255.192, to which subnet does the host
belong?
A. 172.16.2.32
B. 172.16.2.64
C. 172.16.2.96
D. 172.16.2.128
E. 172.16.2.192
Answer: D
Explanation: When we look at the last octet of the subnet mask, we have 192=128+64, which is the two high
order mask bits, leaving 6 bits for host addressing. Each subnet strides 64 addresses, including broadcast,
leaving the following networks:
172.16.2.0
172.16.2.64
172.16.2.128
172.16.2.192
We now look at the host address, which is 160, and find that it fits between 128 and 192, so the network is
172.16.2.128.
