A subnet mask is a 32-bit number used in computer networks to divide an IP address into network and host portions. It helps identify the network address by determining which part of an IP address belongs to the network and which part belongs to the host.

Network Mask:
A subnet mask, also known as a network mask, is a set of numbers used to determine the network portion of an IP address. It is applied to the IP address by performing a bitwise AND operation, enabling the router or device to understand the network address required for routing packets.
Example sentence: The subnet mask 255.255.255.0 is commonly used for class C IP addresses.

Masking of IP Addresses:
Subnet masking is the process of using a subnet mask to define the network and host portions of an IP address. By performing an AND operation between the IP address and subnet mask, the network address can be determined, allowing for proper delivery of data packets within a network.
Example sentence: The correct subnet mask must be applied to the IP address to establish communication between different subnets.
-
Local Subnet:
In the context of local networks, a local subnet refers to a specific portion of a network identified by a subnet mask. It allows for the division of a larger network into smaller, more manageable subnetworks, improving network efficiency and facilitating better control over network traffic.
Example sentence: Our company's local subnet consists of the IP addresses ranging from 192.168.0.1 to 192.168.0.254.
