About:
mmdbctl is a command-line interface tool designed for comprehensive management of MaxMind MMDB database files. It enables users to inspect, create, modify, and validate MMDB files without requiring a database server. The tool serves as an essential utility for developers working with GeoIP data, offering capabilities to convert formats and efficiently handle large datasets.
Key Features:
  • Inspect and query MMDB database files
  • Create new MMDB databases from various input formats
  • Merge multiple MMDB files into a single database
  • Validate and verify database integrity
  • Convert between different database formats
Use Cases:
  • Managing custom GeoIP databases for network security applications
  • Converting IP address data from CSV or other formats into MMDB for application integration
  • Validating and debugging MMDB files before deployment in production environments
Alternatives:
  • mmdbinspect – Part of the maxminddb package, offers read-only inspection with fewer management features
  • maxminddb-golang – Library for programmatic access rather than a comprehensive CLI management tool
