Question

how many usable host addresses are available for each subnet when 4 bits are borrowed from a class C IP address

Answer 1

The answer is "14".

Step-by-step explanation:

Let the IP address
`= 196.45.204.0`

When it borrowed 4 bits

`\therefore\\\\ subnet = 28`

`IP= (196.45.204.0)/(28)\\\\ 28 \to 11111111.11111111.11111111.11110000`

If the borrowed bits are left out then:

The Number of useable host addresses:

`= {(2^4) - 2} \\\\ = 16-2\\\\ =14`
