In infrastructure projects — especially within Kubernetes, on-prem networks, or bare-metal environments — proper IP address management is essential. That’s why I developed ipam, a lightweight and reliable tool for managing IP allocation in modern environments.
What is ipam? Link to heading
ipam (short for IP Address Management) is a minimalistic tool for managing IP ranges and allocating free addresses. Unlike full-featured network systems, this tool focuses on simplicity, clarity, and automation-friendliness, making it a great fit for DevOps engineers and SREs who automate infrastructure at scale.
Key Features Link to heading
- Define IP pools using CIDR notation (e.g.
192.168.100.0/24) - Allocate the first available IP in a given pool
- Mark IPs as reserved or used
- Simple CLI interface — easily scriptable in CI/CD or Ansible workflows
- JSON-based storage — no need for an external database
Use Cases Link to heading
- IP allocation during deployment of services or VMs
- Reserving static IPs for specific hosts in bare-metal environments
- Checking whether a specific IP is free or in use
- Integrating with automation tools like Ansible, Terraform, or simple Bash scripts
Getting Started Link to heading
First, clone the project and build the binary:
git clone https://github.com/hoseinmontazer/ipam
cd ipam
go build -o ipam .
In many real-world projects, there’s no need to spin up complex systems like Infoblox or NetBox. Sometimes you just need a small tool that can help you allocate and track IPs — fast, lightweight, and dependency-free.
This project is open source, and contributions are welcome! If you have a feature request or found a bug, feel free to open an issue or submit a pull request.
