Is there any benefit to saving private range ips with vlsm?

Question

Computer networks

Hello, there are 9 vlans, each needs to be allocated an ip subnet. I calculated that the number of required addresses does not exceed 254, which means that a network with a 24-bit mask is enough for me, I will split it into networks with masks / 26, / 27, / 28, etc.
But if we say the vlan numbers are 101,102,103,104, then it would be easier to understand if for each vlan I selected a separate network with a /24 mask, and in the 3rd octet I would put the vlan number, for example:
vlan101 = 172.16.101.0/24
vlan102 = 172.16.102.0 /24

In the first variant 254 addresses are obtained, in the second 2286.

Question: Is it necessary to save addresses? Or do it as it is easier to perceive, but give 10 times more addresses and why?

Answer 1

Do not do shit if you have enough 254 addresses on the network, use networks with a mask / 24 and do not fence the garden.

Answer 2

It all depends on the task.
IMHO It’s more convenient for me to break it into / 24, and there is a margin and it looks nicer for the eyes)

Answer 3

Think one step ahead. Today, there are, say, two nodes, and tomorrow ten more will need to be connected there. And you again fence the garden with vlan and subnets.
If the problem can be solved simply - solve it simply.
