A network administrator needs to implement a new IP subnet containing 29 hosts. It is possible that the number of hosts in that subnet could eventually double. The company only has a single, unused public IP network left to work with: 164.10.12.0/24.
Which of the following would be the BEST way to divide this network without wasting addresses?
A . 164.10.12.0/24
B . 164.10.12.64/29
C . 164.10.12.128/26
D . 164.10.12.191/28
Answer: C
