NAME

       mmdbresolve - Read IPv4 and IPv6 addresses and print their IP geolocation information.

SYNOPSIS

       mmdbresolve [ -v ]

       mmdbresolve [ -h ]

       mmdbresolve -f <dbfile> [ -f <dbfile> ] ...

DESCRIPTION

       mmdbresolve reads IPv4 and IPv6 addresses on stdin and prints their IP geolocation information on stdout.
       Each input line must contain exactly one address. Output is in INI format, with a section delimiter named
       after the query address followed by a set of "key: value" pairs. A comment beginning with "# End" is
       appended to each section.

       At startup an "[init]" section is printed that shows the status of each database and of mmdbresolve
       itself.

OPTIONS

       -v
           Print version information and exit.

       -h
           Print help information and exit.

       -f
           Path to a MaxMind Database file. Multiple databases may be specified.

EXAMPLES

       To resolve a single address:

           echo 4.4.4.4 | mmdbresolve -f /usr/share/GeoIP/GeoLite2-City.mmdb

       Example output

           [init]
           db.0.path: /usr/share/GeoIP/GeoLite2-City.mmdb
           db.0.status: OK
           mmdbresolve.status: true
           # End init
           [4.4.4.4]
           # GeoLite2-City
           country.iso_code: US
           country.names.en: United States
           location.latitude: 37.751000
           location.longitude: -97.822000
           # End 4.4.4.4
