# mmdbresolve(1)

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

## 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
```
