๐Ÿ‘€ Main Features

๐Ÿ“• 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:

npm install && npm run build

Run:

npm 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

๐Ÿ“š Environment Variable

Variables marked Yes below must be set for the backend to function correctly. The MaxMind credentials in particular are required โ€” read the setup notes in the next subsection before filling in the table.

MaxMind Databases (Required)

MyIP relies on the free GeoLite2 databases from MaxMind (City + ASN) for IP geolocation, ASN / organization lookup, and the country-code badges that appear throughout the app (IP cards, WebRTC ICE candidates, and more). A working MaxMind setup is required for the backend to serve a complete experience.

The .mmdb files are not checked into this repository because MaxMind's GeoLite2 license does not allow redistribution. You need to provide them yourself. There are two paths:

Option A โ€” Automatic (recommended, required for Docker)

  1. Create a free account at maxmind.com/en/geolite2/signup.
  2. Generate a license key from your account's "Manage License Keys" page.
  3. Set these three environment variables:
    MAXMIND_ACCOUNT_ID="your-account-id"
    MAXMIND_LICENSE_KEY="your-license-key"
    MAXMIND_AUTO_UPDATE="true"
    
  4. Start the backend. Within about 60 seconds of the first startup, the updater will download both databases. They are then refreshed every 24 hours automatically.

โš ๏ธ Docker deployers must use Option A. A fresh container ships with an empty common/maxmind-db/ directory โ€” without the three variables above the backend starts, but the MaxMind-powered IP source and WebRTC country badges will not work, and you'll see MaxMind API will return 503... in the logs on every boot.

Option B โ€” Manual (for air-gapped or non-Docker setups)

Download GeoLite2-City.mmdb and GeoLite2-ASN.mmdb from your MaxMind account and drop them into common/maxmind-db/ before starting the backend. With this approach MAXMIND_AUTO_UPDATE can stay "false", but you'll need to refresh the files manually as MaxMind publishes new versions.

Environment variables list

Variable Name Required Default Value Description
MAXMIND_ACCOUNT_ID Yes "" MaxMind account ID, paired with MAXMIND_LICENSE_KEY to download GeoLite2 databases. See the MaxMind section above.
MAXMIND_LICENSE_KEY Yes "" MaxMind license key, paired with MAXMIND_ACCOUNT_ID. See the MaxMind section above.
MAXMIND_AUTO_UPDATE Yes "false" Set to "true" to auto-download GeoLite2 databases ~60s after startup and refresh every 24h. Required for Docker. Can stay "false" only if you've pre-seeded the .mmdb files manually.
VITE_GOOGLE_ANALYTICS_ID Yes "" Google Analytics ID, used to track user behavior
BACKEND_PORT No "11966" The running port of the backend part of the program
FRONTEND_PORT No "18966" The running port of the frontend part of the program
SECURITY_RATE_LIMIT No "0" Controls the number of requests an IP can make to the backend server every 60 minutes (set to 0 for no limit)
SECURITY_DELAY_AFTER No "0" Controls the first X requests from an IP every 20 minutes that are not subject to speed limits, and after X requests, the delay will increase
SECURITY_BLACKLIST_LOG_FILE_PATH No "logs/blacklist-ip.log" Path setting. Records the list of IPs that triggered the limit after SECURITY_RATE_LIMIT is enabled
LOG_LEVEL No "info" Minimum log level (debug / info / warn / error). Lower-level messages are suppressed.
LOG_FORMAT No pretty Set to "json" to emit one JSON event per line (for log aggregators / jq). Any other value (or unset) keeps the colored pretty output used in dev and pm2 log tails.
LOG_HTTP No "false" Set to "true" to enable per-request HTTP logging on /api/* (method, URL, status, response time). Off by default to keep pm2 logs lean. Handler-level 4xx/5xx errors are always logged regardless of this flag.
ALLOWED_DOMAINS No "" Allowed domains for access, separated by commas, used to prevent misuse of the backend API
GOOGLE_MAP_API_KEY No "" API Key for Google Maps, used to display the location of the IP on a map
IPCHECKING_API_ENDPOINT No "" API endpoint for IPCheck.ing database, used to obtain accurate IP geolocation information
IPCHECKING_API_KEY No "" API Key for IPCheck.ing database, used to obtain accurate IP geolocation information
IPINFO_API_TOKEN No "" API Token for IPInfo.io, used to obtain IP geolocation information through IPInfo.io
IPAPIIS_API_KEY No "" API Key for IPAPI.is, used to obtain IP geolocation information through IPAPI.is
IP2LOCATION_API_KEY No "" API Key for IP2Location.io, used to obtain IP geolocation information through IP2Location.io
CLOUDFLARE_API No "" API Key for Cloudflare, used to obtain AS system information through Cloudflare
MAC_LOOKUP_API_KEY No "" API Key for MAC Lookup, used to obtain MAC address information
VITE_CURL_IPV4_DOMAIN No "" Provides the IPv4 domain for the CURL API to users
VITE_CURL_IPV6_DOMAIN No "" Provides the IPv6 domain for the CURL API to users
VITE_CURL_IPV64_DOMAIN No "" Provides the dual-stack domain for the CURL API to users

Note that if any of the CURL series environment variables are missing, the CURL API will not be enabled.

Using Environment Variables in a Node Environment

Create environment variables:

cp .env.example .env

Modify .env, and for example, add the following:

BACKEND_PORT=11966
FRONTEND_PORT=18966
MAXMIND_ACCOUNT_ID="YOUR_ACCOUNT_ID"
MAXMIND_LICENSE_KEY="YOUR_LICENSE_KEY"
MAXMIND_AUTO_UPDATE="true"
GOOGLE_MAP_API_KEY="YOUR_KEY_HERE"
ALLOWED_DOMAINS="example.com"

Then restart the backend service.

Using Environment Variables in Docker

You can add environment variables when running Docker, for example:

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 GOOGLE_MAP_API_KEY="YOUR_KEY_HERE" \
  -e ALLOWED_DOMAINS="example.com" \
  --name myip \
  jason5ng32/myip:latest

๐Ÿ‘ฉ๐Ÿปโ€๐Ÿ’ป 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

๐Ÿ˜ถโ€๐ŸŒซ๏ธ Additional Notes

When version 2.0 was released, I said that 70% of the code for this program was not written by me, but by AI. After about 90 interactions, plus some minor manual adjustments, the entire codebase was completed.

Of course, the architecture and UI still required my own design.

With the release of version 3.0 and subsequent versions, the proportion of code written with the help of AI has gradually decreased, now estimated to be between 40% and 50%. On the contrary, in this process, I went from having no knowledge of JavaScript and Vue to being able to understand most of the JS code, and I can now write some on my own.

Thanks to AI, it has given me, an unemployed product manager, a rapid opportunity to learn programming.
