MMDBRESOLVE(1)                                             MMDBRESOLVE(1)

NAME         top

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

SYNOPSIS         top

       mmdbresolve [ -v ]

       mmdbresolve [ -h ]

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

DESCRIPTION         top

       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         top

       -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         top

       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
