Question

A host was given the IPv4 address 192.168.3.219/27. What are the total number of hosts available in the network? Select one: оооо

Answer 1

30 host

Step-by-step explanation:

Express the mask in binary:

11111111.11111111.11111111.11100000

So, all one-bits represent the prefix and all zero-bits represent the host

The number of host available is given by:

`Number-of-hosts=2^(n) -2`

Where:

n=The number of bits not taken up by the prefix, in this case, n=5

The reason of the -2 it is because of the Network Address and the Broadcast address. These addresses are not available for node addressing.

Hence:

`Number-of-hosts=2^(5) -2=32-2=30`
