Quickly calculate CIDR, subnet mask, network address, and usable IP range.
About This Tool
The CIDR Calculator is a comprehensive tool for network engineers and developers. It calculates network address, broadcast address, subnet mask, wildcard mask, IP class (A/B/C), and usable host range/count based on IP and CIDR mask. It features binary and hexadecimal visualizations to help understand IP addressing and subnetting principles.
