Which of the following IP addresses belong to the Class A network 114.0.0.0? (select three)

  1. 114.58.12.0

  2. 114.0.0.15

  3. 114.122.66.12

  4. 115.0.0.1

The correct answer is: 114.58.12.0

The Class A network is defined as any IP address that starts with a number from 1 to 126, and its subnet mask provides a large number of possible hosts within its range. The Class A network 114.0.0.0 allows for addresses from 114.0.0.1 to 114.127.255.254. In this context, the addresses within the range of 114.0.0.0 are the ones that fit this criterion. The addresses beginning with 114 and falling within this range are 114.58.12.0, which is valid, 114.0.0.15, which is also valid, and 114.122.66.12, which is again properly addressed. The address 115.0.0.1 does not belong to the Class A network 114.0.0.0 since it starts with 115, which is not part of the 114.0.0.0 Class A network range. Therefore, the addresses 114.58.12.0, 114.0.0.15, and 114.122.66.12 fit the classification correctly as they are all part of the Class A network defined
