Jump to PostHello,

Isn't hard to calculate:

192.168.30.0 with mask 255.255.255.0 has 256 IPs with

192.168.30.0 net ID and 192.168.30.255 brodcast adress.

This is equivalent with notation 192.168.30.0/24. 24 represent the number of bits used in mask.

255.255.255.0 - 11111111.11111111.11111111.00000000 that means 24 bits.Lets split the network.

Your initial network have mask.

255.255.255.0 - 11111111.11111111.11111111.00000000 - that means 24 bits.255.255.255.128 - 11111111.11111111.11111111.10000000 - that means 25 bits

Your initial network is splited in 2 subnets (2^1)

255.255.255.192 - 11111111.11111111.11111111.11000000 - that means …
