How to solve the network problem?

Question

Computer networks

help solve the problem.
"Allocate address space for 2 computer networks. Leave maximum space for new networks."

Answer 1

Before making a decision, it is desirable to clarify the following:
1) Find out how many devices are in each subnet (N1, N2)
2) Find out if expansion is planned
3) If it is planned, then at what pace
Actually, the decision.
Find the base 2 logarithm for the numbers N1, N2, round up.
This will be the number of bits for subnet 1 and subnet 2. For example, in the first network there are 43 machines, in the second 27.
That is, occupied by hosts will be 6 bits for the first subnet, 5 for the second. Thus, for the first subnet it will be a mask of 32 -6=26 bits, for the second - 32-5=27.
First network:
Mask: 255.255.255.192
Network: 192.168.0.0/26
Addresses: 192.168.0.1 - 192.168.0.62
Broadcast: 192.168.0.63
Second network:
Mask: 255.255.255.224
Network: 192.168.0.64/27
Addresses: 192.168.0.65 - 192.168.0.94
Broadcast: 192.168.0.95
The first network can be expanded up to 62 machines, the second - up to 30
Something like this. In principle, everything is conditional, maximum space for new networks

Answer 2

maybe not "space" but "space"? some sort of auto translation?
the minimum size of a meaningful subnet is 4 addresses, the mask is 255.255.255.252.

Answer 3

I would file 10.1.0.0/16 and 10.2.0.0/16 or 10.0.1.0/24 and 10.0.2.0/24
