Question

ou work for a large communications corporation named ITGlobe which has been assigned a Class C network address 192.1.42.3. Currently, the company has 500 subnets
in offices around the country. If all offices use the broadcast address what will it be?

Answer 1

As per the question,

IP address 192.1.42.3 belongs to the class C,

Class C network ID $=192.1.42.0$

First host id=192.1.42.1

Last host id=192.1.42.255

But as we know that 255.255.255.255 is the broadcast id, so last host id will be

Last host id=192.1.42.254

But here total number of required host =500 hence it requires broadcast id so the required ip address will be

192.1.42.255
