What does subnetting accomplish

Class B networks use a default subnet mask of Class C networks use a default subnet mask of When the IP system was first introduced, it quickly became clear that although it was now far easier to find a specific network, it was also now difficult to send a data packet to the machine you want on that network.

This becomes particularly apparent when a network becomes large enough to support an organisation, where network performance becomes more of an issue. Subnets help to solve this problem by breaking up the network into smaller parts, reducing congestion as a result. Data packets are then able to flow directly to their destination and avoid any individual bottlenecks. An organisation can use IP subnets to divide larger networks for logical reasons firewalls, etc , or physical requirements smaller broadcast domains, etc.

In other words, routers use subnets to make routing choices. Subnetting is also used to improve network security , as the divisions between each subnet allow organisations to enforce access controls - which also helps to contain any security incidents. As with an IP address, a subnet mask comprises four bytes 32 bits and is written in the same notation as an IP address, typically this is The subnet mask complements an IP address and by applying it to the IP address and it determines what subnet an IP address belongs to.

An IP address has two components, the network address and the host address. Seek out a qualified computer engineer using Field Engineer to improve the technological capability of your company. Businesses in the twenty first century need to be organized, focused, and resilient to external threats. A confident subnetting capability will help you to achieve your technological business goals. What is Subnetting, Benefits, and How does it Work?

What is Subnetting? What is Subnetting used for? How does Subnetting work? Benefits of Subnetting Subnetting divides broadcast domains, meaning that traffic is routed efficiently, improving speed and network performance. A subnet mask ensures that traffic remains within its designated subnet. This reduces major congestion and reduces the load imparted on the network.

With sub-networks, less distance needs to be traveled by data packets, enhancing network performance. With different subnets within your larger network, you can be more aware of route maps.

To use these calculators to subnet your network, you must first determine how many subnets you need and the maximum number of hosts on each subnet. In this post, I am going to talk about the 10 computer networking concepts that every professional should master. I will also include links to the main articles of each concept.
