A subnet is a shortened term for a sub-network. It is part of the internet Protocol, or IP services used in computer technology. It is an integral part of the system, and it has been around since even before the World Wide Web.
There are several reasons for subnetting:
A subnet mask divides a network that uses the internet protocol (IP) addressing scheme into multiple subnetworks. An internet address has two parts: a network address and a host address.The network address defines group of members (hosts, computers, machines) in a network. The host address defines and actual host, computer, or machine that is a member of the network.
-The subnet mask identifies what bits in the IP address are to be used to represent the network/subnet portion of an IP address.

It does not require a subnet mask.
If this is a default subnet mask, then it would be a class C subnet mask. If you are subnetting a network and this is not the default subnet mask, then it could be either a class A or class B.
The default subnet mask has a standard size. The custom subnet mask allows you to make subnets that are smaller or larger than the default.
To determine the network or subnet address of an IP address
The correct term is subnet mask instead of subnet mass. A subnet mask separates an IP address into the host address and the network address. It is a 32-bit number that can mask an IP address.

A subnet mask is something that divides the IP address into a host and network. It is a very confusing thing but it will also let you see the IP address of the user.
Subnet mask for the above is 255.0.0.0
The default subnet mask would be 255.255.0.0 for a class B address.
if the ip address is 192.168.2.1 then the subnet mask should be 255.255.255.0
