The role of subnet division: 1. Divide the addresses of the three categories ABC into finer network segments using masks to save IP addresses as much as possible and avoid waste; 2. Improve network performance; 3 , can ensure the security of the network; 4. It is easy to expand the geographical scope and helps cover large geographical areas.

What is the role of subnetting?

Subnet division definition:

Internet organizations define five types of IP addresses, including A, B, Class C address. There are 126 Class A networks, and each Class A network may have 16,777,214 hosts, which are in the same broadcast domain. It is impossible to have so many nodes in the same broadcast domain. The network will be saturated due to broadcast communication. As a result, most of the 16777214 addresses are not allocated.

The IP network based on each class can be further divided into smaller networks. Each subnet is defined by the router and assigned a new subnet network address. The subnet address is a host that borrows the network address based on each class. Partially created. After dividing the subnet, the subnet is hidden by using a mask so that the network does not change when viewed from the outside. This is the subnet mask.

By subnetting, we can divide the network into small networks according to our needs. This also helps reduce traffic and hide network complexity.

The role of subnetting

1. It can save IP addresses and avoid waste

The address ranges of categories A, B, and C are relatively large , causing a serious waste of IP addresses. In order to improve the utilization of IP addresses, the addresses of the three categories ABC are divided into finer network segments using masks to save the waste of IP addresses as much as possible!

2. Improve network performance

3. Can ensure network security

4. Easy to expand geographical scope and help cover large geographical areas.
