## What it is
The Go source code powering ipify, a free public API service that returns a client's public IP address, serving billions of requests per month. It builds into a single static binary designed for Heroku but deployable on any web host.

## Use cases
- get my public IP address programmatically
- find the outbound IP of a cloud server during provisioning
- self-host my own public IP lookup API
- configure DNS records with the server's external IP
- check public IP from shell scripts and CI pipelines

## When to choose
- you need a fast, reliable public IP echo endpoint
- you want to self-host an IP lookup service with a single static binary
- you need an extremely high-traffic IP API with millisecond response times

## When to avoid
- you need geolocation or ISP metadata about the IP, not just the address
- you need IPv6-only or advanced filtering features not supported by the service
- you want a managed service without deploying anything yourself

## Facets
- artifact type: service
- maturity: stable
- function: http-server, api-framework, networking
- domain: networking, apis, developer-tools, self-hosted
- platform: go, self-hosted
- tags: public-ip, ip-address-api, ipify, heroku, linux, web-server
