Understanding IP Subnetting

Subnetting is the practice of dividing a network into two or more smaller networks. It increases routing efficiency, enhances network security, and reduces the size of the broadcast domain.

Key Concepts

Why Calculate Subnets?

Network Design

Engineers need to know how many usable IPs are available in a block to ensure they can connect all required devices (servers, printers, workstations).

Troubleshooting

Knowing the correct gateway and broadcast address is essential for configuring routers and firewalls correctly.

Frequently Asked Questions

Everything you need to know about using this free online tool.

CIDR stands for Classless Inter-Domain Routing. It is a method for allocating IP addresses and IP routing. The /24 notation indicates the number of bits used for the network prefix.
In every subnet, the first address is the Network Address (identifies the subnet) and the last address is the Broadcast Address (used to communicate with all hosts). Neither can be assigned to a specific device.
