Netsleuth

Netsleuth is a command-line utility for Linux designed to calculate IP subnets. It assists network administrators and system operators in performing subnet calculations, determining network ranges, and analyzing IP addressing schemes directly from the terminal. The tool processes standard IPv4 and IPv6 notation to yield detailed network parameters without requiring manual arithmetic.

Operating as a specialized utility, Netsleuth takes CIDR blocks or IP addresses with netmasks as input and outputs relevant data such as network addresses, broadcast addresses, usable host ranges, and total host counts. Its focused scope makes it suitable for scripting and quick reference during network configuration tasks on supported Linux systems.
