IPMG — IP Management & Ping Monitoring Tool

Scan and monitor IP networks from the command line — or from a local web dashboard. IPMG pings hosts in parallel, resolves hostnames, and exports results as Excel, CSV, JSON, or Markdown reports.

Security note: only scan networks you are authorized to scan. Unauthorized scanning may violate your organization's policies or the law.

Install

pip install ipmg

Check that it works:

ipmg --version

uv tool install git+https://github.com/sameeralam3127/ipmg.git

curl -sSL https://raw.githubusercontent.com/sameeralam3127/ipmg/main/install.sh | bash

git clone https://github.com/sameeralam3127/ipmg.git
cd ipmg
pip install -e .

Quick start

# Scan your local subnet automatically
ipmg --discover

# Scan a single host
ipmg --input 8.8.8.8

# Scan a CIDR range
ipmg --input 192.168.1.0/24

# Scan an IP range
ipmg --input 10.0.0.1-10.0.0.50

# Scan targets from a file (xlsx, csv, txt, or list)
ipmg --input targets.txt

# Resolve hostnames and export CSV + a readable Markdown report
ipmg --input targets.txt --resolve --formats md csv

# Scan and report what changed since the previous scan
ipmg --input targets.txt --compare

# List stored scans, then compare any two of them
ipmg history
ipmg diff 12 14

# Open the local web dashboard
ipmg dashboard

Running plain ipmg uses ip_list.xlsx as input and creates a sample file if it does not exist.

Change detection

Every scan is stored in a local SQLite history (~/.ipmg/dashboard.db), shared by the CLI and the dashboard. IPMG can then tell you what moved between any two scans.

ipmg --input targets.txt --compare                   # compare with the previous scan
ipmg diff                                            # compare the two latest scans
ipmg diff 14                                         # compare scan 14 with the one before it
ipmg diff 12 14                                      # compare two specific scans
ipmg diff --diff-formats md json                     # export the change summary
ipmg diff --fail-on-change                           # exit 2 when anything changed (CI)
ipmg history --limit 10                              # list stored scans

Detected changes:

A latency change is only reported when it clears both --latency-threshold (default 5 ms) and --latency-pct (default 25%), which keeps normal jitter out of the report.

By default a scan is compared against the previous scan of the same target source, so file-based and --discover runs do not get mixed up.

Web dashboard

ipmg dashboard          # starts http://127.0.0.1:8080 and opens your browser

A modern browser UI that shares the CLI's scanning engine and runs fully offline — every stylesheet and script is bundled with the package, nothing is loaded from a CDN. It gives you:

• Dashboard — status donut, latency trend, and recent scan overview
• New Scan — upload Excel/CSV/text/JSON target files or type IPs, CIDR blocks, and ranges; configure threads, timeout, and DNS options
• Live Monitor — real-time progress and results over WebSockets
• History — every scan stored locally in SQLite (~/.ipmg/dashboard.db), searchable and downloadable as XLSX/CSV/JSON/Markdown
• Changes — pick any two scans and see new/offline hosts, IP and hostname moves, and latency shifts; export the summary as Markdown/JSON/CSV
• Inventory — every host seen across scans, with last status and export

ipmg web is an alias for ipmg dashboard.

Options

Exit codes: 0 success, 1 error, 2 changes detected (ipmg diff --fail-on-change), 130 interrupted.

Input formats

• Excel / CSV — must contain an IP Address column:

  IP Address
  192.168.1.1
  10.0.1.0/30

• Text file — one IP or CIDR per line; blank lines and # comments are ignored:

  # Production DNS
  8.8.8.8
  192.168.1.0/30
  

• Command line — a literal IP (8.8.8.8), CIDR block (10.0.0.0/24), or IP range (10.0.0.1-10.0.0.200)

Duplicate targets are removed automatically, and one scan expands to at most 65,536 hosts — larger CIDR blocks or ranges are rejected up front.

Output

  ipmg 1.8.1  ·  scan
  ICMP probes only — scan only networks you are authorized to scan.

  Source   targets.txt
  Targets  3 hosts

Colors follow NO_COLOR, the progress bar is hidden when output is piped, and the symbols fall back to ASCII on terminals that cannot render them.

Result files (e.g. results_20260628_120000.xlsx) contain one row per host:

Status values: Active, Inactive, Timeout, Unreachable, Invalid IP, Error.

The md format produces a shareable Markdown report with a status summary table — handy for tickets, handoffs, and incident timelines.

Security

IPMG is built for scanning networks you are authorized to scan, and the tool itself is hardened accordingly:

• Pings run as a direct process call (no shell), and every target is validated as an IP address first
• The dashboard binds to 127.0.0.1 by default and serves everything locally — no CDN assets, no outbound requests
• WebSocket connections are origin-checked, so a web page you happen to visit cannot connect to the local dashboard and read your scan results
• Uploads are capped at 5 MB and one scan expands to at most 65,536 hosts, so a bad input file cannot exhaust memory
• All database access uses parameterized SQL

If you bind to a non-local address with --host, anyone who can reach that interface can start scans and read results — put a reverse proxy with authentication in front of it.

Found a vulnerability? See SECURITY.md for how to report it.

Troubleshooting

• command not found: ipmg — make sure pip's script directory is on your PATH, or reinstall with pip install ipmg.
• Hostname shows Unresolvable — the host has no DNS PTR record.
• Input file rejected — check the extension is supported and that spreadsheets/CSVs include an IP Address column.

Development

pip install -e ".[dev]"
PYTEST_DISABLE_PLUGIN_AUTOLOAD=1 pytest -q

Releases are automated: merging a conventional commit (feat: ..., fix: ...) to main triggers GitHub Actions to run tests, create a semantic-release tag, and publish to PyPI.

GitHub Pages demo

The dashboard also has a static, interactive demonstration at sameeralam3127.github.io/ipmg. GitHub Pages cannot run the Python scanner or access a local SQLite database, so this version transparently uses realistic seeded network inventory and scan history. Search, filters, comparison, exports, theme switching, and a manual demo scan all work in the browser. The local ipmg dashboard command always uses the real FastAPI API and scan engine instead.

The Deploy dashboard demo to GitHub Pages workflow publishes src/ipmg/web/static after changes to main. In repository settings, select GitHub Actions as the GitHub Pages source once; no secrets are required.

To review the static experience locally, run any static web server from src/ipmg/web/static and open it with ?demo=1:

cd src/ipmg/web/static
python3 -m http.server 4173
# http://127.0.0.1:4173/?demo=1
