Well, I understand the concept of Subnet Mask, the thing I don't really get are the "Subnets"
For exemple, with 18.104.22.168/23
I could have 8 networks with 62 hosts each. The thing is: I don't get it what does it actually mean.
They all have the Subnet Mask 255.255.254.0, but they are also different networks. How is this possible?
