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

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

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 datbase and of mmdbresolve itself.


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

To resolve a single address:

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

Example output

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