Subnet IDs

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 /26

192.168.100.0 /24 becomes the following if a /26 is applied to it

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
192.168.100.192 /26

yes, or network IDs interchangably
