📕 How to Use

Deploying in a Node Environment

Make sure you have Node.js installed.

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.

Using Docker

Click the 'Deploy to Docker' button at the top to complete the deployment. Or, use the following shell:

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

📖 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

⚙️ Configuration

Two settings matter before anything else:

• MaxMind GeoLite2 (required) — free credentials that power IP geolocation and ASN lookups. Without them, the MaxMind source returns 503. → MaxMind Setup
• ALLOWED_DOMAINS (required on a real domain) — 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.

👩🏻‍💻 Advanced Usage

If you're using a proxy for internet access, consider adding this rule to your proxy configuration (modify it according to your client). This setup lets you check both your real IP and the IP when using the proxy:

# IP Testing
IP-CIDR,1.0.0.2/32,Proxy,no-resolve
IP-CIDR6,2606:4700:4700::1111/128,Proxy,no-resolve
DOMAIN,4.ipcheck.ing,DIRECT
DOMAIN,6.ipcheck.ing,DIRECT
# Rule Testing
DOMAIN,ptest-1.ipcheck.ing,Proxy1
DOMAIN,ptest-2.ipcheck.ing,Proxy2
DOMAIN,ptest-3.ipcheck.ing,Proxy3
DOMAIN,ptest-4.ipcheck.ing,Proxy4
DOMAIN,ptest-5.ipcheck.ing,Proxy5
DOMAIN,ptest-6.ipcheck.ing,Proxy6
DOMAIN,ptest-7.ipcheck.ing,Proxy7
DOMAIN,ptest-8.ipcheck.ing,Proxy8
