MyIP

A simple, high-performance, and scalable API that returns a client's public IP address. Built with Go and the Fiber web framework, it's designed to handle extremely high traffic with minimal resource usage.

This service correctly identifies the visitor's real IP address, even when behind a reverse proxy or CDN like Cloudflare.

Live Version

A public and rate-limit-free version of this service is deployed and maintained by DynX.

• IPv4 & IPv6: https://myip.dynx.pro
• IPv4 Only: https://ipv4.myip.dynx.pro
• IPv6 Only: https://ipv6.myip.dynx.pro

Features

• ✅ Returns the visitor's public IP address in plain text.
• 🚀 Blazing fast and lightweight, thanks to Go and Fibe.
• ⚙️ Optimized for high-concurrency environments with Fiber's Prefork feature.
• 🌐 Listens on both IPv4 and IPv6.
• 🔒 Reliably detects the real client IP behind proxies.

Performance

The MyIP service demonstrates high-performance capabilities for handling concurrent HTTP requests. As shown in the benchmark above, the application is capable of processing over 60,000 requests per second with low latency (~21 ms average) under heavy load.

This test was performed from an 8-core server to a 2-core server (host: myip.dynx.pro) using wrk with 8 threads and 1000 concurrent connections over a 15-second duration. The results highlight the efficiency of the server in returning simple plaintext responses, making it ideal for low-latency, high-throughput scenarios.

Installation & Usage

Prerequisites

You need to have Go installed on your server.

Steps

1. Clone the repository

   git clone https://github.com/MrDevAnony/MyIP.git
   cd MyIP

2. Edit .env file This command opens the .env configuration file in the nano text editor, allowing you to modify its contents.

   nano .env

3. Build the application This command compiles the source code into a single executable binary named MyIP.

   go mod init MyIP && go mod tidy && go build -o MyIP main.go

4. Run the application The server will start and listen on port 3000.

   ./myip

5. Test it You can now get your IP by making a request to the server. IPv4:

   curl http://(IPv4 or IPv6):3000/

Running as a Systemd Service

To ensure the application runs continuously in the background, automatically starts at boot, and restarts if it fails, you can set it up as a systemd service.

1. Create the Service File Open a new service file with a text editor like nano:

   sudo nano /etc/systemd/system/MyIP.service

2. Add the Configuration Copy and paste the following content into the file. Important: Make sure the ExecStart and WorkingDirectory paths match the location where you built your application. The example below assumes your project is in /root/MyIP.

   [Unit]
   Description=MyIP Service
   After=network.target
   
   [Service]
   ExecStart=/root/MyIP/MyIP
   WorkingDirectory=/root/MyIP
   Restart=always
   User=root
   Group=root
   
   [Install]
   WantedBy=multi-user.target

3. Enable and Start the Service Run the following commands to reload the systemd manager, enable your service to start on boot, and start it immediately.

   # Reload the systemd daemon to recognize the new service
   sudo systemctl daemon-reload
   
   # Enable the service to start automatically on boot
   sudo systemctl enable MyIP.service
   
   # Start the service right away
   sudo systemctl start MyIP.service

4. Check the Status You can verify that the service is running correctly with the following command:

   sudo systemctl status MyIP.service
