Hi All,

Can someone please assist with this question;

When subnetting with a /24, how many host bits are on. As I understand it, when using a class C, there are 0 host bits on and 8 host bits off. In this instance, how many subnets does this address provide for.

Again, as I understand it, if you use this mask with a class B address, there will be 8 bits on and 8 bits off.

Similarly, with a class A address (using this mask), you will have 8 bits on and 16 bits off.

Is my undertanding of this mask correct?

Lastly, does anyone know how to start a new post (an entirley new topic).

Looking forward to a few responses.

Kind regards,

Ian Ward
