Hi,
Well i been going through some vlsm examples and i have been thinking that what if we need more hosts than 126 Hosts in any network, consider this example:-
we have 4 networks
Network A has 145 hosts
Network B has 130 hosts
Network C has 90 hosts
Network D has 40 hosts
and our network ip is a Class B ip, so how are we gonna solve this kind of problem, using vlsm.
Thank you,

Say you are given a Class B subnet such as 172.16.0.0/16
You want to maximize the class given and avoid wasting space, let's start with Network A:
145 hosts won't fit under a /25 because you were only have 126 hosts so it will be under /24
Network A = /24
Next, we run under the same situation for Network B, thus /24
Network C requires 90 hosts, it won't fit under /26 since it only allows for 62 hosts but it fits under /25
Network D will fit under /26
To recap:
Network A: 172.16.0.0/24
Network B: 172.16.1.0/24
Network C: 172.16.2.0/25
Network D: 172.16.2.128/26
