MyIP (branded as IPCheck.ing) is an open-source IP toolbox that provides browser- and server-based network diagnostics. It detects local and public IPs, shows geolocation/ASN details, and bundles utilities for availability, DNS and WebRTC testing.

Key Features

• Detects and displays local and public IPv4/IPv6 addresses and associated metadata (country, region, ASN, geolocation).
• IP search and detailed IP information lookup with geolocation and ASN data.
• DNS Leak Test that reports DNS endpoints to evaluate VPN/proxy DNS leakage risk.
• WebRTC connection detection to reveal IPs exposed via browser peer connections.
• Network tests: speed test, global latency tests, ping, and MTR from multiple edge locations.
• Availability/Censorship checks to verify whether major sites or a specific domain are reachable from different regions.
• DNS resolver comparison across multiple sources to help identify DNS contamination or propagation issues.
• Proxy rule testing to validate proxy configuration rules and behavior.
• Whois search and MAC lookup utilities.
• Browser fingerprinting options, keyboard shortcuts, dark/minimalist modes, PWA support and multi-language UI.

Use Cases

• System administrators and security engineers diagnosing VPN, DNS or routing issues and checking for DNS leaks or WebRTC exposure.
• Network-savvy users validating ISP-assigned IPs, performing speed/latency tests, and checking regional availability or censorship of services.
• Operators who want a packaged set of IP/network diagnostics (whois, DNS, MTR, ping, traceroute-like tests) for troubleshooting and reporting.

Limitations and Considerations

• Some features depend on browser capabilities (e.g., WebRTC detection and certain fingerprinting methods) and may not work in all browsers or when restrictive privacy extensions are active.
• Geolocation and ASN accuracy depend on third-party IP/data providers; results may vary by region and provider freshness.
• Map display requires a provider API key configuration for full map functionality; out-of-the-box deployments may show limited or no map view until configured.

MyIP (IPCheck.ing) provides a comprehensive, ready-to-deploy set of IP and network diagnostic tools intended for troubleshooting and investigation. It bundles multiple practical tests and utilities in a single open-source project suitable for both individual and operational use.
