About:
mmdbinspect is a command-line utility designed to query one or more MaxMind MMDB databases for IP address or network information. It allows users to perform batch lookups against multiple database files simultaneously, outputting results in a structured JSON format. This tool simplifies the process of inspecting and correlating geolocation, ISP, or threat intelligence data stored in MMDB format.
Key Features:
  • Batch processing of IP/network lookups
  • Support for multiple MMDB database files in a single query
  • Structured JSON output for easy parsing and integration
  • Command-line interface for scripting and automation
Use Cases:
  • Debugging geolocation or ISP data discrepancies by inspecting raw MMDB records
  • Automated enrichment of network logs with threat intelligence or location data
  • Validating custom or updated MaxMind database files before deployment
Alternatives:
  • mmdblookup – Part of libmaxminddb; mmdbinspect offers easier batch queries and JSON output
  • geoiplookup – Legacy tool for GeoIP legacy (dat) files; not compatible with MMDB format
