MyIP

MyIP is a self-hosted web-based toolbox for checking your IP address, geolocation, and running network diagnostics including DNS leak tests, speed tests, WebRTC detection, and proxy rule validation. Built in Vue with Node.js backend, it supports Docker deployment and PWA installation.

What MyIP is

Vue 3 frontend with Node.js backend providing IP geolocation via MaxMind GeoLite2 databases, DNS resolution from multiple sources, latency/MTR testing to regional servers, WebRTC candidate analysis, and speed testing. Requires explicit MaxMind credentials (free tier available) and supports environment-driven configuration for rate limiting, logging, and analytics.

Quickstart

Get the MyIP source

Clone the repository and explore it locally.

terminalbash

1git clone https://github.com/jason5ng32/MyIP.git2cd MyIP3# follow the project's README for install & configuration

Best use cases

Self-hosted IP diagnostics platform

Organizations needing on-premise IP lookup, DNS leak detection, and network diagnostics without external service dependencies or data sharing concerns.

VPN/proxy testing and validation

Teams validating proxy rules, detecting WebRTC leaks, and verifying DNS endpoint behavior before deploying to users.

Network troubleshooting and monitoring

Technical users performing MTR tests, latency checks across global regions, and website availability validation from a single interface.

Implementation considerations

MaxMind GeoLite2 setup is mandatory—requires free account creation and license key management (Option A for Docker) or manual .mmdb file seeding (Option B for air-gapped environments).
Environment variables for Google Analytics, rate limiting, and logging levels must be configured before deployment; defaults are permissive and may need hardening.
CAIDA dataset auto-update is optional but recommended for accurate ASN topology and org-name lookups; manual refresh required if disabled.
Rate limiting and request delay controls are configurable but disabled by default; assess traffic patterns and set SECURITY_RATE_LIMIT and SECURITY_DELAY_AFTER accordingly.
Supports both Node.js and Docker; choose Docker if you want automatic MaxMind database updates; Node.js deployment requires manual database provisioning.

When to avoid it — and what to weigh

Managed SaaS preferred — If you require a fully managed service with zero infrastructure overhead, this requires deployment and maintenance of both frontend and backend.
Offline-first requirements — The application requires internet connectivity to reach external IP sources, test remote servers, and download MaxMind databases.
Enterprise audit/compliance mandates — While MIT-licensed, internal security review and validation of third-party data sources (MaxMind, CAIDA) will likely be required before enterprise use.
Real-time streaming analytics — Designed as a manual diagnostic tool; not intended for high-frequency automated monitoring or real-time data pipeline integration.

License & commercial use

MIT License (Expat variant). Permissive open-source license allowing use, modification, and distribution in commercial and proprietary contexts, provided copyright and license text are included.

MIT License permits commercial use without explicit permission or fees. However, verify compliance with MaxMind GeoLite2 and CAIDA terms separately—MaxMind explicitly prohibits redistribution of .mmdb files, and CAIDA datasets have their own licensing. Internal commercial deployment of MyIP itself faces no license barrier, but bundling or distributing the application with pre-loaded geolocation data requires independent review of upstream data licenses.

Security considerations

Application enables optional rate limiting and request-delay controls (SECURITY_RATE_LIMIT, SECURITY_DELAY_AFTER) to mitigate abuse. Logs can be emitted as JSON for aggregation (LOG_FORMAT=json). CodeQL workflow indicates static analysis scanning. Data sourcing includes third-party IP geolocation (MaxMind), DNS resolvers, and external latency/MTR servers; review the privacy and security posture of these dependencies. No explicit HTTPS/TLS enforcement in the documentation; reverse proxy is recommended for production. Google Analytics integration should be reviewed for privacy compliance.

Alternatives to consider

IPQualityScore / IP2Location (SaaS)

Managed services offering IP geolocation, threat scoring, and abuse detection without infrastructure overhead; requires API key and ongoing costs.

Shodan or Censys (CLI tools / APIs)

Specialized for security research and threat hunting; broader internet-wide scanning scope but steeper learning curve and commercial pricing.

mtr / traceroute / dig (CLI utilities)

Lightweight, built-in Unix tools for latency and DNS testing; no UI, requires command-line expertise, and no geolocation or browser fingerprint features.

MyIP FAQ

Do I need to pay for MaxMind to use MyIP?

No. MaxMind GeoLite2 is free for non-commercial use. You register for a free account, generate a license key, and configure MyIP with MAXMIND_ACCOUNT_ID and MAXMIND_LICENSE_KEY. Commercial use of MyIP itself is allowed under MIT, but verify MaxMind's GeoLite2 commercial terms separately.

Can I run MyIP behind a reverse proxy or on a subdomain?

Yes. Both frontend and backend ports are independently configurable via environment variables (FRONTEND_PORT and BACKEND_PORT). Configure your reverse proxy to forward requests appropriately and ensure CORS or same-origin setup is correct.

What happens if MaxMind databases fail to download or expire?

If MAXMIND_AUTO_UPDATE is enabled, the backend will attempt to re-download on the next 24-hour cycle. If auto-update is disabled (Option B), you must manually replace the .mmdb files. Meanwhile, the MaxMind-dependent IP source will return 503 or incomplete data; other features (DNS, latency, WebRTC detection) remain unaffected.

Is there an SLA or enterprise support?

Unknown. MyIP is a community open-source project maintained by a single developer. No commercial support, SLA, or warranty is documented. For production use, evaluate your tolerance for self-managed troubleshooting and potential downtime.
