Subnet Calcv1.0.0

Network engineers plan and allocate IP ranges for new office branches or data center expansions. They use subnet-calc to calculate subnet masks, host ranges, and broadcast addresses to ensure efficient IP utilization and avoid overlaps.

DevOps engineers automate VPC and subnet creation in cloud platforms. They integrate subnet-calc to validate CIDR blocks before provisioning, ensuring they fit within existing network topology without conflicts.

Security analysts check if IPs from threat feeds fall within internal network ranges. Using the --contains flag, they quickly identify whether an IP is part of a known corporate subnet for incident response.

ISPs manage large CIDR blocks and split them into customer allocations. Subnet-calc with --split helps partition a /22 block into /24 subnets for different clients, outputting JSON for integration with billing systems.

Instructors demonstrate subnetting concepts with real-time calculations. They use the plain output format to show binary representations and explain how masks work, aiding student understanding.

Offer a free CLI version for basic calculations and a premium API/cloud service with batch processing, collaboration, and advanced reporting for network teams.

License subnet-calc as a module for existing network management or provisioning software, enabling in-app subnet calculations without external tools.

Package subnet-calc with interactive tutorials, quizzes, and study materials for network certification. Sell as a standalone product or bundled with courses.
