Azure Network Calculator

Offline Azure network planning tool. Calculates CIDRs, detects overlaps, analyzes VNet utilization, plans AKS networking, and generates Terraform-ready output. Zero external dependencies — uses Python stdlib only.

Quick Start

# What CIDR do I need for 500 hosts?
python3 scripts/network-calc.py calculate --from-hosts 500

# Analyze current VNet
python3 scripts/network-calc.py analyze --from-tfvars terraform/terraform.tfvars

# Validate for overlaps (pre-commit compatible)
python3 scripts/network-calc.py validate --from-tfvars terraform/terraform.tfvars
