Currently doing my Google certifications and struggling with the concept of subnet masking. I understand how it works in terms of identifying the network and host ids, what I don’t understand is why it is necessary.
If the octates that identify the network I’d need the ip to be interpreted, why is the the ip address not just used? They use the same number of bits, so how does it extend the range of available ip addresses?

Subnet masking is how *much* of a network you want your host to see in the immediate – without routing – area.
Any packet that does not fit the mask is sent to the router, anything that does is sent to the switch.
