IP9

A dead simple Golang program that returns your IP address and country.

Country detection uses ip2region, a free and open-source offline IP geolocation library (Apache 2.0). No API keys or external services are required at runtime.

Example response:

203.0.113.42
Australia (AU)

Build and run with docker-compose:

docker compose up -d

For local development, download the ip2region databases first:

sh scripts/download-data.sh
go run .

Alias

Add a convenient alias to your ~/.bashrc or ~/.zshrc:

alias ip9='curl ip9.ir'

Then reload your shell config:

source ~/.bashrc  # or source ~/.zshrc

Now you can simply run ip9 in your terminal to get your IP address:
