LAN subnet —

LAN Subnet



If you're setting up a Local Area Network (LAN), one of the things you'll need to consider is how you're going to allocate the IP addresses to devices on the network. One common way to do this is to divide the network into subnets, with each subnet having its own range of IP addresses.



A subnet is a portion of a network that shares a common addressing scheme. Typically, a subnet will consist of a range of IP addresses that all share a common network prefix. This prefix is used to identify the network portion of the address, while the remaining bits are used to identify individual devices on the network.



By dividing your network into subnets, you can gain several benefits. For example, you can reduce network traffic by limiting the number of devices that need to communicate with each other. You can also improve security by separating devices into different subnets with different access controls.



To create a subnet, you'll need to choose a subnet mask that defines the range of IP addresses that will be assigned to devices on the network. This mask is typically expressed as four numbers separated by dots, such as 255.255.255.0. The numbers indicate how many bits of the IP address are used to identify the network portion of the address.



Overall, setting up a LAN subnet can be a bit technical, but it can offer several benefits for your network. With careful planning and attention to detail, you can create a subnet that is both efficient and secure.
