Internet Protocol (IP) Self Test

Correct!

CIDR notation uses the format xxx.xxx.xxx.xxx/n, where 'n' is the number of '1' bits in the network mask. This means the network 192.168.11.0/21 actually contains all addresses in the range 192.168.8.0 - 192.168.15.255. Conversely,

  • the network 192.168.10.0/22 only contains addresses in the range 192.168.8.0 - 192.168.11.255
  • the network 192.168.12.0/23 only contains addresses in the range 192.168.12.0 - 192.168.13.255, and
  • the network 192.168.13.0/24 only contains addresses in the range 192.168.13.0 - 192.168.13.255.
