How Many Host Addresses Are Available in the 172.27.0.0/28 Network?

B

The IP address 172.27.0.0/28 is a Class B network with a subnet mask of 255.255.240.0. The /28 denotes the number of bits that are used for the network portion of the address, leaving 4 bits for the host portion.

To calculate the number of available host addresses, we need to subtract 2 from the total number of possible host addresses. This is because the first and last IP addresses in the range are reserved, one for the network address and one for the broadcast address.

In this case, the total number of possible host addresses is 2^4 - 2 = 14. Therefore, the answer is B. 14 host addresses are available in the 172.27.0.0/28 network.

The available IP addresses for hosts in this network are:

• 172.27.0.1 to 172.27.0.14

The network address is 172.27.0.0, and the broadcast address is 172.27.0.15.

It's important to note that the size of the network (the number of host addresses available) depends on the subnet mask. Changing the subnet mask can increase or decrease the number of available host addresses.
