SUBNET Meaning and
Definition
-
A subnet, short for subnetwork, is a smaller division or segment of a larger network. It refers to the process of partitioning a network into smaller, more manageable subgroups called subnets. This division allows for improved network performance, increased security, and efficient routing of network traffic.
In TCP/IP networking, a subnet is defined as a portion of an IP network address space. It is formed by borrowing bits from the host portion of an IP address and allocating them for use as a subnet prefix. This process creates a new network address range, known as a subnet, which can contain a specific number of hosts or devices.
Subnets are implemented to logically group devices that share common characteristics or are geographically located in close proximity to each other. Each subnet has its own unique network address, subnet mask, and host addresses. The subnet mask helps in determining the network and host portions of an IP address.
Subnetting allows network administrators to efficiently manage network traffic by controlling communication between subnets. It enables the use of routing protocols, such as Border Gateway Protocol (BGP), to effectively direct traffic between different subnets. Additionally, subnets can be established to enhance network security by limiting access between different segments and implementing network policies at a subnet level.
In summary, a subnet is a smaller division of a larger network that aids in optimizing network performance, improving security, and enabling efficient routing of network traffic.

Etymology of SUBNET
The word "subnet" is a combination of two terms: "sub" and "net".
- "Sub" is a prefix of Latin origin, meaning "under" or "below". It often implies lower rank or position.
- "Net" is a shortened form of "network", which refers to a collection of interconnected devices or computers.
