VLSM Examples

Say we have the IP: 210.19.14.0/24

We want to create to networks which support this many hosts

Doing A first(because it's bigger):

Third octet in our IP has the bit pattern of 0000 11100

If we want to support 1000 hosts we need to borrow the last two bits of that pattern:

problem: one of those is 1 which means we can't borrow it as its part of our given network address.

Thus this problem then can't be done given this information.
