Here are 3 facts about the network portion of an IPV4 address.
1. identical for all hosts in a broadcast domain
2. varies in length
3. is used to forward packets
unique name of individual person within the link
network address
The host portion of an IP address of all zeros indicates that you are referring to 'this network'. For example, the address 145.5.0.0 means the network 145.5
To seprate an ip address from the network address we use subnet mask that can seprate the ip address from the network address
Seeing as the IP address of 128.107.10.11 is a class B network, the host portion is 10.11
An "ip address" is a complete source or destination address that has a network id portion and a client or host portion. The network id is just a piece of the IP address. So, a public ip is an IP address that can be routed, whereas the network id is just a part of the public ip. They aren't different; the network id is part of the ip address.
An IP address must be unique within a LAN; the combination of the network and host portion must present a number that is not duplicated anywhere else in the network. Outside of a LAN the IP addresses do not have to be unique, except that the network id portion can only be used by the organization that owns the IP network address. The host portion does not need to be unique across all LANs within an enterprise network.

Subnet mask
The network address of this ip address is 192.150.8 and 24 is host ip address
Because this is the way you can easily and quickly isolate the network portion from the host portion of the address to just get the network id, which would be using for routing purposes.
The network part of an IP address indicates the network to which the host belongs. The host bits or host part of an IP address points to the actual device that has an IP address on the network. It can be a computer, printer, router or any device with an IP address that has the same network part.
The subnet mask is used for this purpose. It indicates how much of the address is for network, and the remaining part is for the hosts.
What is the Network mask of IP 185.185.0.0 in dotted decimal? How do I calculate First host of the major network IP address? What would be my last host of the major network?"
