About the App
"What is my current IP address?" "Is my VPN working correctly?"
Verify your network connection status with a single tap.
『IP Checker』 is a diagnostic tool that displays your current global IP address, hostname, and connection region without any complex steps.
Beyond simple information display, it features proxy/VPN detection and network privacy audits.
Key Features
- Detailed IP Info: Check Global IPv4/IPv6, hostname, and ISP (Internet Service Provider) at a glance.
- Proxy & VPN Detection: Automatically detects if your connection is routed through an intermediary server. Perfect for verifying VPN operation.
- Estimated Location: Displays an approximate connection location (city level) based on your IP address, integrated with maps.
- Privacy Audit: Evaluates information leakage risks and security based on your network configuration.
- Connection History: Automatically logs past IP address changes so you can track network fluctuations.
- Network Metrics: Quality checks including latency (ping) and MTU size.
Developer's Vision
I wanted to recreate the experience of using "Check IP" web services on a mobile device, but with more power and convenience.
In today's internet landscape, knowing your connection status—whether it's verifying public Wi-Fi security or confirming a VPN connection for remote work—is more important than ever.
My goal is to provide detailed data that satisfies everyone from tech-savvy engineers to general users, all within a simple interface.
