The range of network addresses refers to the allocation range of IP addresses used to identify different networks. According to the IPv4 protocol, IP addresses are divided into three classes: A, B, and C. Each class has its own network address range and host address range. Here is a detailed explanation of the network address ranges for class A, B, and C:

Class A Network Address Range

Network address range: 1.0.0.0 to 126.0.0.0

Subnet mask: default is 255.0.0.0

Host address range: 1.0.0.1 to 126.0.0.254

Class B Network Address Range

Network address range: 128.0.0.0 to 192.0.0.0

Subnet mask: default is 255.255.0.0

Host address range: 128.0.0.1 to 192.0.0.254

Class C Network Address Range

Network address range: 192.0.0.0 to 223.255.255.0

Subnet mask: default is 255.255.255.0

Host address range: 192.0.0.1 to 223.255.255.254

Configuration Options

When configuring a network, it is necessary to choose the appropriate network class based on actual needs. Here are some common configuration options:

It's important to note that the host portion of class A and B networks can be further divided into subnets to achieve finer network segmentation and management. Class C networks are typically used for small-scale local area networks or individual devices.
