Subnet Mask used to determin the Network part and the Host part within the IP Address
Subnetmask is use to isolate the network ID and Host ID. eg- if an IP is:192.168.0.1 then the default subnet is:255.255.255.0 because it is a C Class Address C Class Add. have3 network octate and1 host octate .The main purpose of subnetmasking is to reduce the broadcast domain or in other words to reduce to heavy network traffic.
subnet mask is used to differentiate your network from others . it uses for the large scale companies . its allow you to network scalibility .
Submask mask is used to divide an IP address into network and node, and the limit the number of IP addresses available on a network.
An IP address of the form255.0.0.0 (1 number for network,3 for node) is called a Class A network An IP address of the form255.255.0.0. (2 for network,2 for node) is called a Class B An IP address of the form255.255.255.0 (3 for network,1 for node - most common) is called a Class C network.
We need a subnet mask for IPv4 addresses because the address doesn't give any information on the network size. Class sizes are not the network sizes. In practical networks all IPv4 networks are broken up into subnets that are smaller than the class size.
For example you could break up the class C network200.200.200.0/255.255.255.0 into two smaller networks (potentially at separate locations)200.200.200.0/255.255.255.128 and200.200.200.128/255.255.255.128 assuming neither needed more than126 hosts. In reality most companies only get enough IPv4 addresses for the servers that need to be on the public Internet. I've personally seen set ups with32,16, &8 address networks (that would be masks of255.255.255.224,255.255.255.240, &255.255.255.248 respectively)

subnet mask used to define network ( or subnetwork ) number
Subnet Mask is a common32-bit address that is used along with a particular IP address. This is used to divide network ID and Host ID. The main use of the subnet mask is to divide large Network in to smaller one according to requirements.
Subnets are created to separate areas of your network for security and/or to hold down broadcasts.
Subnetting allows you to divide areas of your network
subnet mask is used to devide the large network into smaller networks,to proide security and prevent unnecessary brodcasts, simplefies administration and control growth. . it uses for the large scale companies . its allow you to network scalibility .
A Subnet mask is used to divide an IP address into 2 parts. one part identifies the host, and the other one shows the network to which it belongs to.
