Definition of Functions and objectives of subnetting on computer networks 

In this article we will discuss the notion of subnetting on computer networks. Subnetting also has the function and purpose of subnetting on computer networks.

Why do you have to do subnetting? Some of us must definitely do subnetting for some reason, one of the reasons why we have to do subnetting is:

In this article we will discuss the notion of subnetting on comp networks. Understanding the function and purpose of subnetting on computer networks
  1. To streamline the allocation of IP Address addresses in a computer network in order to maximize the use of IP addresses.
  2. To overcome the problem of differences in hardware (hardware) and physical media used by a network, because IP routers can only integrate as a network with different physical media if each network has a unique network address.
  3. To increase security on computer networks

For more details, see the explanation below.

Definition of Subnetting

Subnetting is a process of breaking an IP network into smaller sub-networks called “subnets”. Each subnet is a non-physical description (or ID) for sub-physical networks (usually the network switches from a host containing one router in a multi-network).


Subnetting can only be done on ip address class A, Class B, class C. Subnetting will create several additional networks but reduce the maximum number of hosts in each network.

The purpose of subnetting

The purpose of subnetting is as follows:

  1. To streamline network addressing, for example for networks that only have 10 hosts, if we want to use class C there are 254 – 10 = 244 unused addresses.
  2. Can divide one network class over a number of subnetworks with the articulate dividing a network class into smaller parts.
  3. To overcome the problem of differences between hardware and physical network topology.
  4. To make more efficient allocation of Ip addresses on a network in order to maximize the use of ip adderss.
  5. To improve security and reduce the occurrence of congestion due to too many hosts in a network.
  6. To overcome the problem of differences in hardware and physical media used in a network.

Subnetting function

  • Helping the development of networks towards geographical distance away.
  • Reducing network traffic, so that data passing through the company will not cause collisions (data collisions).
  • More optimized network work.
  • Making network management simpler.

Okay, he was discussing the understanding, purpose, and function of subnetting. Hopefully this short article can be useful and help you for those who read it.
