Is there a difference between NetID and Network Address?

[immazali]

So i know the gist of it. Thanks to the help here

Network Address i see as anything ending with 0 Example: 192.168.0.0

Broadcast Address i see as anything ending with 255 Example: 192.168.0.255

Whereas NetID i honestly just see in theory as what your network is identified as, example 192.168.0.X

But let me know if i am wrong. Just curious?

terminology is best placed in a context
I guess with NetID you mean the combination of network address PLUS netmask
whereas the "Network Address" is the lowest address in the range determined by the NetID

about network and broadcast address, you are almost right
.0 and .255 is only thru if you have a /24bit subnet (mask 255.255.255.0) but there are more possibilities
e.g.  a /25bit subnet (mask 255.255.255.128)  divides a 192.168.0.0//24 network in two separate networks
each with it's own network and broadcast adresses

NetworkID              - network address/ broadcast address
192.168.0.0/24     - 192.168.0.0       / 192.168.0.255 
each /25 network can be further divided in a /26 ( /27, /28, /29, /30)
192.168.0.0/25     - 192.168.0.0       / 192.168.0.127
192.168.0.128/25 - 192.168.0.128   / 192.168.0.255
two /24 networks can be combined into a /23 (/22, /21, /20 ......)
192.168.0.0/23     - 192.168.0.0       / 192.168.1.255

try a internet search on "subnet calculator" or "network calculator"and enter some data,
this might be of help to you to visualize network addressing

This wrong 

Only the subnet /24 it broadcast is .255 and netId is .0 

Other subnet need to check it broadcast and network id and useable hosts.

You can use any online subnet calculator to get this information

A network address is an unique identification for a network host.  For example, your IP address for the PC you use is its L3 network address.  BTW, your PC likely also has a L2 network address, such as an Ethernet MAC.

For IP, a network address is compromised of two ID numbers, the network ID (NetID) and host ID.  Also with IP, the number of bits allocated for those two IDs can vary.

For the following, all have a network and host IDs of 1 (one).

1.0.0.1/8

0.1.0.1/16

0.0.1.1/24

0.0.0.17/28

BTW, you mistakenly appear to believe IPv4's dotted decimal has something to do with what's the network and host IDs are.  It doesn't, but it's easy to think this due to IPv4's Classful addressing history.
