🤔 Frequently Asked Questions (FAQ)

What is a subnet?

A subnet is a subdivision of an IP network that allows better segmentation and organization of connected devices, improving efficiency and network security.

How does subnet calculation work?

The calculator converts the CIDR into the corresponding subnet mask, identifies the network IP, the broadcast address, and the available host range.

What does CIDR mean?

CIDR (Classless Inter-Domain Routing) is a method of allocating IP addresses that uses a decimal suffix to define network size. Example: 192.168.0.0/24.
