Subnet IDs

in CCNA & CCENT
When subnetting what does the term Subnet ID mean?
I understand how to subnet, just a bit confused what the term subnet ID means.
Seem to be finding slightly different definitions.

I think you are looking for network ID.... or that is way I have always looked at it. You have two unusable addresses under normal circumstances,
the network address, and the broadcast address
192.168.100.0 /24 is a network ID (not a valid IP address)
it can be broken into two networks if you used a /25
192.168.100.0 /25
192.168.100.128 /25
192.168.100.0 /24 becomes the following if a /26 is applied to it
192.168.100.0 /26
192.168.100.64 /26
192.168.100.128 /26
192.168.100.192 /26I don't claim to be an expert, but I sure would like to become one someday.

So would all of the below be subnet IDs then?
192.168.100.0 /26
192.168.100.64 /26
192.168.100.128 /26

yes, or network IDs interchangablyI don't claim to be an expert, but I sure would like to become one someday.
