Overview

IPInfoDB offers free geolocation lookups that map IP addresses to country, region, city, and time zone data. Registration is required but free, and the service provides simple RESTful endpoints with JSON or XML output. It is a reliable choice for projects that need basic IP-to-location functionality without a high budget.

💡
