echoip is a simple IP address lookup service written in Go.

The tool solves the problem of quickly determining IP address information and geolocation. It works by accepting IP address queries and returning details such as geographic location, ASN, and other network metadata. The service can be queried via HTTP requests and returns results in multiple formats including JSON and plain text, making it easy to integrate into scripts and applications.

The project suits developers who need a lightweight, self-hosted alternative to commercial IP lookup services. It works well for applications requiring IP geolocation without external API dependencies, and for those who want to run the service on their own infrastructure. The tool is particularly useful for system administrators and developers building tools that need to resolve IP addresses to geographic or network information.

The project shows consistent maintenance with regular updates addressing bugs and adding incremental improvements. Development activity demonstrates responsiveness to issues and pull requests, with fixes and enhancements being merged steadily. The codebase remains focused on its core functionality without significant feature bloat, reflecting a pragmatic approach to maintenance.
