IPv4 Subnet

An IPv4 subnet is a specific range of IP addresses that is divided into multiple parts by routers. These parts are called address blocks and are assigned to devices connected to the network.

An IPv4 subnet consists of the following parts:

Network address: The address of the network itself, which is usually the first few bits.
Broadcast address: The address that is used by the network itself and all devices on the network.
Number of usable addresses: The number of addresses available in the subnet.
Number of assigned addresses: The number of addresses assigned to devices on the subnet.

For example:

Network address: 192.168.1.0
Broadcast address: 192.168.1.255
Number of usable addresses: 254
Number of assigned addresses: 254

Note: The subnet mask is used to determine which addresses are assigned to devices on the network. The subnet mask consists of 32 bits, where each bit represents a network or host bit.

Benefits of Subnetting:

Increased security: Subnetting can be used to create isolated networks that are more difficult for unauthorized users to access.
Improved performance: Subnetting can improve performance by allowing the operating system to allocate memory and resources more efficiently.
Flexibility: Subnetting allows you to adjust the size of your network as needed
