🧰 MyIP - A Better IP Toolbox

👀 Features

🪪 Your IP & Identity

• 🛜 IP Cards: Detects your IPv4 and IPv6 from multiple independent sources side by side — country, region, city, ASN, organization, and the IP's local time zone.
• 🔍 Query IP: Looks up the same detailed information for any IP address you're curious about.
• 🧾 IP History: Keeps a local record of the IPs you've been seen with, filterable by type and country — stored in your browser only.
• 🖥️ Browser Fingerprint: Calculates your browser fingerprint in multiple ways and shows what makes you identifiable.

🕵️ Leaks & Privacy

• 🚥 WebRTC Detection: Reveals the IP address exposed during WebRTC connections — including whether your browser's privacy hardening is on.
• 🛑 DNS Leak Test: Shows which DNS endpoints resolve your queries, to evaluate the risk of DNS leaks when using VPNs or proxies.
• 📋 Security Checklist: A 258-item personal cybersecurity checklist across 12 areas, with progress saved in your browser.

📡 Network Tests

• 🚦 Connectivity Check: Tests the reachability of up to 60 sites of your choice, with multi-round minimum-latency results — plus curated import lists, from country packs to AI, social, streaming, gaming, developer, and more. Based on the results, it signals whether global internet access is currently feasible for you.
• 🚀 Speed Test: Measures your download, upload, and latency against edge networks.
• ⏱️ Global Latency Test: Pings your target from probes all over the world — pick countries from all available Globalping probes, grouped by continent.
• 🚉 MTR Test: Runs MTR from globally distributed probes to see the route packets actually take.
• 🚧 Censorship Check: Shows where a website is blocked worldwide — and by what means.
• 🚏 Proxy Rule Test: Verifies that your proxy software's rule configuration works the way you intended.

🔦 Lookup & Infrastructure

• 📟 DNS Resolver: Resolves a domain through multiple resolvers at once, grouped by country — an easy way to spot hijacking or contamination.
• 📓 Whois Search: Performs Whois lookups for domain names and IP addresses.
• 🗄️ MAC Lookup: Identifies the vendor and details behind a physical address.
• 🛰️ ASN Info & Upstream Topology: Shows AS details, historical announcements for an IP prefix, and the upstream paths from an ASN to the Tier 1 backbone.
• 📶 Service Status: Live availability of well-known services — Claude, OpenAI, GitHub, Cloudflare, and more — from their official status pages, with recent incidents.

✨ Platform

• 📤 Shareable Reports: Turn your test results into a diagnostic report — a read-only link with auto-expiry, AI-ready Markdown, or JSON.
• ⌨️ Curl API: Get your IP from the terminal with a single curl command.
• 🌍 Earth Online: A panel broadcasting global internet outage events as they happen.
• 🌗 Dark Mode: Follows your system automatically, with a manual toggle.
• 📲 PWA: Installable as an app on your phone and as a Chrome app on your desktop.
• ⚡ Keyboard Shortcuts: Every function has one — press ? to see the list.
• 🔤 Multiple Languages: The UI ships in 6 languages, and adding yours takes one locale pack.

📕 How to Use

Using Docker

One command and you're up:

docker run -d -p 18966:18966 --name myip --restart always jason5ng32/myip:latest

Or click the "Deploy with Docker" button at the top of this page.

Deploying in a Node Environment

Make sure you have Node.js installed, then clone the code:

git clone https://github.com/jason5ng32/MyIP.git

Install and build. This project uses pnpm — if you don't have it, install it first (npm ships with Node, so this command always works):

npm install -g pnpm
pnpm install && pnpm run build

Run:

pnpm start

The program will run on port 18966.

⚙️ Configuration

[!IMPORTANT] MaxMind GeoLite2 credentials are required. They power IP geolocation and ASN lookups — without them, the MaxMind source returns 503. They're free: → MaxMind Setup

[!WARNING] ALLOWED_DOMAINS is required on a real domain. It's the hostname allowlist for the backend API — without it, every request from a non-localhost domain gets 403. → Reverse Proxy & Domains

docker run -d -p 18966:18966 \
  -e MAXMIND_ACCOUNT_ID="YOUR_ACCOUNT_ID" \
  -e MAXMIND_LICENSE_KEY="YOUR_LICENSE_KEY" \
  -e MAXMIND_AUTO_UPDATE="true" \
  -e ALLOWED_DOMAINS="your-domain.com" \
  --name myip --restart always \
  jason5ng32/myip:latest

Everything else — optional API keys, security & rate limiting, logging, Sentry, the curl API domains — is documented in the Environment Variables reference.

📖 Documentation

Full guides live in the MyIP Docs Center: docs.ipcheck.ing

• Developer Guide — deployment, configuration, architecture, and contributing
• Knowledge Base — how to use every tool, step-by-step network diagnosis, and networking concepts

🤝 Contributing

Contributions are welcome! We keep a curated set of beginner-friendly tasks — each with exact file paths, acceptance criteria, and tests that guide you to a green build:

• 🏷️ Good first issues — add a DNS resolver from your country, add curated site lists, translate the README into your language, polish translations, and more
• 🌐 TRANSLATING.md — bring the UI to your language: a locale pack plus one registry line, and a partial translation is a welcome first PR
• 📄 CONTRIBUTING.md — setup, conventions, and how PRs flow (target the dev branch)
