diverdale/ipam repository overview

⁠diverdale/ipam

A lightweight IP Address Manager for home labs. Single container, no external database — SQLite-backed Go backend with a React frontend.

⁠Features

• Subnet management (add/edit/delete CIDRs)
• Ping scan with live progress via SSE
• Reverse DNS hostname discovery
• ARP MAC address discovery
• Host tracking (active/offline status, last seen)

⁠Quick Start

Create a docker-compose.yml:

services:
  ipam:
    image: diverdale/ipam:latest
    container_name: ipam
    restart: unless-stopped
    network_mode: host
    volumes:
      - ./config:/config

Then run:

docker compose up -d

Open http://<host-ip>:8080 in your browser.

⁠Notes

• Config and SQLite database are stored in ./config/ on the host
• Scans run inside the host network namespace so the ARP table is fully visible
• Hostname discovery uses reverse DNS (PTR records) — results depend on your DNS setup
