Subnet Chart

Subnetting is a fundamental building block of any IPv4 network. It allows you to divide an entire network into smaller, more specific parts so they can be managed effectively. There are many benefits to subnets, including increased efficiency when it comes to managing them.

The perfect way to keep your office running smoothly is by creating a network of subnets. Subnetworks provide the connectivity within one branch or office, which means that all devices connected will be able to communicate with each other easily. Access control lists (ACLs) can be applied at the routing layer to control which devices on which subnets can communicate with other devices on other subnets.

To help make subnet calculations extremely simple, we are giving you two free resources - a subnet chart, which you can download and save or print for reference, an online subnet calculator, which you can use on your computer or phone to quickly calculate all the relevant details for a subnet, and a subnet API, which you can use to calculate subnets directly from the command line.
